Abstract 

An earlier molecular study demonstrated the monophyly of the Hyptidinae and most of the genera within it. However, 

the largest genus, Hyptis, is paraphyletic and all other genera seem to be derived from a Hyptis ancestor. Most of the 

different lineages which comprise Hyptis are already established sections, some of which are now raised to generic rank, 

augmenting the subtribe to 19 genera and with a greatly reduced but monophyletic Hyptis, in which the genus Peltodon is 

included as a section. The sections Mesosphaeria and Polydesmia are also shown not to be monophyletic, making it 

necessary to reassign some species from the former to the latter, and then raising the two sections to generic rank as 

Mesosphaerum and Cantinoa respectively, the latter a new genus name. A new genus Oocephalus is also created from 

two former subsections of Hyptis sect. Polydesmia. The genus Condea, formed from three former sections of Hyptis, is 

itself divided into two sections. A key to all recognized genera is included, together with a generic conspectus, with brief 

distributional data, differentiating the new genera and listing their component species. The necessary nomenclatural 

changes comprise 142 new combinations, 30 new or replacement lectotypifications, four neotypes, 23 new synonymies, 

eight stat. nov., six newly coined generic names, five new epitypes and four new names. 

Key words: generic key, Hyptis, molecular data, morphology, new genera, taxonomy 

Introduction 

The Lamiaceae have recently undergone major changes of both delimitation and reorganization of constituent 

taxa, as a result of morphological and molecular phylogenetic studies (e.g., Cantino 1992a, 1992b, Wagstaff et 

al. 1995, 1998), with many genera, formerly placed in Verbenaceae, being incorporated (Harley et al. 2004). 

Accepted by Hajo Esser: 18 Jun. 2012; published online in PDF: 27 Jun. 2012 1

Currently, the family comprises about 7200 species, the largest within the order Lamiales, with 240 

genera, divided among seven subfamilies (Harley et al. 2004), of which subfam. Nepetoideae contains over 

50% of all species. Molecular studies on various groups of Nepetoideae have been published, in particular on 

Mentheae by Bräuchler et al. (2010), on Ocimeae by Paton et al. (2004) and more recently by Zhong et al. 

(2010) on the phylogeny of Isodon (Schrad. ex Benth.) Spach (Ocimeae) and allies, suggesting a close link 

between Hyptidinae and Hanceolinae. All these studies are causing a re-evaluation of morphological and 

other non-molecular characters, as well as advancing our understanding of probable evolutionary lines and 

past geographical dispersion. The Ocimeae, distributed through tropical regions, are characterized by having 

stamens declinate above the anterior corolla lip. Although with a largely Old World distribution, one subtribe, 

the Hyptidinae, which forms the subject of this paper, is almost exclusively neotropical, occurring throughout 

tropical and subtropical America, with perhaps two species extending their natural range to Africa, as well as 

several weedy species which are introduced into the Palaeotropics (Harley et al. 2004). Most species are to be 

found in a wide range of primarily savanna habitats, often in upland areas. The Hyptidinae are characterized 

by flowers arranged in variously modified bracteolate cymes, with corollas bearing stamens decurrent and 

held within the hinged anterior corolla lobe, which provides an explosive pollination mechanism (Harley 

1971), and by the possession of nutlets with an expanded areole (Paton & Ryding 1988). 

Taxonomic History of Hyptis and relations 

Bentham (1833), who published the first detailed account of the Labiatae, recognized four genera in the 

group: Peltodon Pohl, Marsypianthes Mart. ex Benth., Hyptis Jacq. and Eriope Humb. & Bonpl. ex Benth., 

considering it a natural group, although the name Hyptidinae did not receive formal recognition until it was 

proposed by Endlicher (1838). The largest of the genera is Hyptis, currently with about 280 species, of which 

Bentham wrote: “it would be more convenient to divide it into a number of genera”, but he was unable to find 

a satisfactory means of separating the wide range in inflorescence form that he encountered. Instead he treated 

the various groups he recognized as sections, later amplifying these in De Candolle’s Prodromus (Bentham 

1848). Also at this time, Schauer (1844) separated a fifth genus, the monotypic Rhaphiodon Schauer, treated 

by Bentham as a species of Hyptis. Kuntze (1891), in the Revisio Genera Plantarum, having discovered an 

earlier name for Hyptis, published a very large number of new combinations under, the generic name of 

Mesosphaerum P.Browne (1756). These however were not generally accepted, leading to Hyptis Jacq. being 

made a conserved name (see McNeill et al. 2006) and considerably adding to the synonymy. No further 

generic additions were made, until Epling (1932) further dismembered Hyptis by publishing the Central 

American genus Asterohyptis Epling, with three species, characterized by the much reduced corollas and 

lacking the explosive pollination mechanism. This was followed by the recognition of Eriopidion Harley 

(1976), a monotypic genus, removed from Eriope, and the subsequent creation of Hyptidendron Harley and 

Hypenia (Mart. ex Benth.) Harley (Harley 1988), removing three sections from Hyptis to raise the number of 

generic taxa in the Hyptidinae to nine. Eight of these were accepted in the most recent account (Harley et al. 

2004), although Atkinson (1999, unpublished thesis) suggested placing all species of Hypenia within Eriope, 

a change not justified according to Pastore et al. (2011) and not followed in the present paper. 

Up to the mid-20 th century, undoubtedly the most important contributions to the taxonomy of New World 

Labiatae were made by Carl Epling, those dealing with the Hyptidinae being particularly relevant here. Two 

publications, A Synopsis of South American Labiatae (Epling 1935, 1936a, 1936b, 1937) and the Revisión 

del género Hyptis (Labiatae) (Epling 1949), remain standard works, and established the infrageneric 

classification in Hyptis (see below). The most recent overview of the group (Harley et al. 2004) recognizes 

eight genera: Hyptidendron, Eriope, Hypenia, Marsypianthes, Hyptis, Peltodon, Rhaphiodon and 

Asterohyptis. Eriopidion was here placed in the synonymy of Eriope.

Infrageneric classification of Hyptis 

Bentham (1833) recognized 19 sections within Hyptis (Table 1), further dividing sect. Cephalohyptis Benth. 

into a number of subsections. Subsequently, he modified this system and recognized 20 sections (Bentham 

1848), further dividing six of these into a series of subsections. Many of these taxa are still in current use. A 

number of minor changes were made by Schmidt (1858) in an account of Labiatae for the Flora Brasiliensis. 

He also introduced an entirely new infrageneric classification for Hyptis, based on inflorescence structure, 

which has been ignored by later workers. John Briquet, from Geneva, published an extensive series of papers 

on Labiatae, mostly in the latter half of the 19 th century, which included many new taxa of Hyptidinae, 

especially from Paraguay. He also extensively revised infrageneric classifications, especially of Hyptis (Table 

1), in Engler & Prantl’s Pflanzenfamilien (Briquet 1897b). Epling (1933, 1935, 1936a, 1936b, 1937) further 

modified the infrageneric classification of Hyptis, basing his system mainly on Bentham, but with some 

changes proposed by Briquet. Later, in his revision of the genus (Epling 1949), he recognized a total of 26 

sections, of which 15 had originally been proposed by Bentham and one by Briquet (1897), although 

subsequent changes had resulted in very different sectional delimitations (Table 1). Changes included Hyptis 

sects. Spicaria Benth. and Pectinaria Benth. being treated as subsections under H. sect. Mesosphaeria Benth.; 

Hyptis sect. Oocephalus Benth. became a subsection under H. sect. Polydesmia Benth.; Hyptis sect. 

Xanthiophoea Benth. was removed, with the three constituent species placed elsewhere: one becoming the 

type of the genus Rhaphiodon, another one, Hyptis lagenaria A.St.-Hil. ex Benth., being placed in H. sect. 

Cyrta Benth., and the third, Hyptis lobata A.St.-Hil. ex Benth., becoming the only representative of a new 

section, H. sect. Hilaria Epling; Hyptis sect. Turbinaria Benth. was placed in synonymy of Hyptis sect. 

Umbellaria Benth. [= Hyptidendron sect. Umbellaria (Benth.) Harley], H. sect. Siagonarrhen Mart. ex Benth. 

subsect. Cymosae Benth. in synonymy of sect. Buddleioides Benth., and H. sect. Siagonarrhen subsect. 

Nudiflorae Benth. into synonymy of Hyptis sect. Hypenia subsect. Densiflorae Benth. Epling (1933, 1936, 

1937) also created 10 new sections (Table 1). He also raised H. sect. Cephalohyptis Benth. subsect. 

Xylodontes Benth. to sectional rank as H. sect. Xylodontes (Benth) Epling. 

In the introduction to his monograph of the genus Hyptis, Epling (1949) followed Bentham in suggesting 

that a case could perhaps be made for the further division of Hyptis into a greater number of genera. While he 

felt at that time that this revolutionary step was not justified, increased knowledge, based on vastly increased 

collections, has now indicated that the idea was not without foundation. 

Harley (1976) also made a number of changes, including the change of the name of the section which 

contains the generic type, H. sect. Cephalohyptis, to H. sect. Hyptis to conform to ICBN rules (see McNeill et 

al. 2006). Five sections accepted by Epling were placed in synonymy or received a change of status. Harley 

transferred the only species of Hyptis sect. Mixtae Epling to Eriope (Harley 1976). In the same publication he 

also removed the species of Hyptis sect. Siagonarrhen subsect. Nudiflorae, including its type, Hyptis latifolia 

Mart. ex Benth., into the synonymy of Eriope. Later, Hyptis sect. Pachyphyllae (Epling) Harley, based on H. 

sect. Eriosphaeria subsect. Pachyphyllae Epling, was created (Harley 1986b). He also transferred H. sect. 

Umbellaria and H. sect. Buddleoides to the genus Hyptidendron, the former as a subsection and the latter in 

synonymy, and, in the same paper, raised H. sect. Hypenia to generic rank (Harley 1988). For a summary of 

these changes see Table 1. As a result of all these taxonomic changes, the number of accepted sections 

currently stands at 24. Most of these taxa had been defined by characters of the inflorescence and floral 

structure, and many form well-defined groups. 

Concurrently with the taxonomy, a series of other studies has substantially contributed to our 

understanding of the interrelationships with the Hyptidinae. Among these are a series of anatomical studies by 

Rudall (1979, 1980, 1981b, 1981c), a brief palynological survey (Rudall 1981a), which now suggests a more 

detailed study would provide significant data to support the new taxonomy, and a survey of chromosome 

numbers (Harley & Heywood 1992) in which some possible relationships were discussed. More recently, 

Pastore et al. (2011) published a molecular phylogenetic analysis of the Hyptidinae, using nuclear sequences 

from the ITS and ETS regions, complemented by sampling four plastid regions (trnL-F, matK, trnS-G, trnD-

T). The sample included all genera of Hyptidinae, 22 of the 24 sections of Hyptis and totalled up to 180 

species. Most of the large number of subsections recognized by Epling were also sampled, only a very few of 

these being unobtainable. 

TABLE 1. Changes in the classification of Hyptidinae. 

Hyptis sections are in normal type and genera are in bold-face. The arrows indicate the changes made. 

The analyses demonstrate the monophyly of the Hyptidinae and of its constituent genera except for 

Hyptis, provided that Hypenia vitifolia (Pohl ex Benth.) Harley is excluded from Hypenia, Eriope simplex 

(A.St.-Hil. ex Benth.) Harley is transferred to Hypenia and Hyptis eximia Epling is transferred to 

Hyptidendron. These taxonomic changes are supported by the morphology. Indeed, for some time, the 

removal of Hyptis vitifolia from Hypenia had been considered by the senior author on purely morphological 

grounds. Hyptis, meanwhile, is shown to be highly polyphyletic, and represented by nine different lineages, 

often composed of single former sections of Hyptis. Two sections, H. sect. Mesosphaeria and H. sect.

Polydesmia, require some relocation of species, while H. sect. Minthidium Benth., H. sect. Polydesmia 

subsect. Oocephalus and H. sect. Laniflorae Epling are grouped to form a clade. The recognition of these at 

the generic level would leave Hyptis monophyletic but still very diverse. At the same time, the former genus 

Peltodon could now only be recognized at sectional level within Hyptis. There is however a need for much 

wider sampling within Hyptis sensu stricto, to resolve its internal sectional structure. 

Materials and Methods 

Taxonomic studies of a large taxon such as the subtribe Hyptidinae, requires a synthesis of data obtained from 

a wide range of disciplines, summarized above, especially detailed studies of herbarium material 

representative of the taxa studied. Over many years, the senior author has been studying this group, both in the 

field and in the herbaria listed here: AAU, ALCB, B, BM, BR, C, CEN, CEPEC, COL, CTES, E, F, FLOR, G, 

HAL, HBR, HUEFS, INPA, IPA, IS, JBSD, JE, K, LE, LINN, M, MA, MANCH, MBM, MG, MO, MS, NY, 

OXF, P, R, RB, S, SP, SPF, TEPB, UB, UC, UEC, UFG, US, W, Z, ZT, with a view to preparing accounts for 

Flora Neotropica. Detailed morphological studies have provided an insight into their relationships, which with 

the new data from molecular studies enables us to set out a new classification. For the purposes of this paper, 

the original bibliography has been examined wherever possible, to check dates of publication, protologues 

and typification, and the volumes of Taxonomic Literature by Stafleu & Cowan published between 1976 and 

1988 have been frequently consulted. 

Conclusions 

The results from the molecular studies (Pastore et al. 2011) clearly require major changes to be made to the 

current classification of the Hyptidinae. One solution would be to reduce all other genera, including 

Marsypianthes and Eriope, to synonymy under Hyptis. This would leave a genus of over 400 species with a 

range of morphology, both vegetative and reproductive which would transcend that found in possibly any 

other genus of Angiosperms. The other alternative, chosen here, is to reorganize groupings along cladistic 

lines, redefining groupings where indicated, and recognizing a much larger number of genera, which would be 

morphologically more homogeneous, more narrowly defined and justified also on morphological, and in 

many cases by chromosomal and anatomical evidence also. A diagram displaying the phylogenetic 

relationships between the genera recognized here is displayed in Fig. 5. Nevertheless, these changes leave an 

open field for more detailed studies on a range of characters, often not previously considered significant, 

which will hopefully provide further support for the taxonomic changes now proposed. 

The decision to erect a substantial number of new genera has resulted in a careful assessment of names 

already available, and names which need to be created. Hyptis was conserved against both Condea Adans. and 

Mesosphaerum P.Browne, which are earlier names (McNeill et al. 2006). Both of these now become 

available, as their types no longer fall within Hyptis as defined in this paper. Only two of the appropriate 

sectional names in Hyptis can be raised to generic rank: Cyanocephalus Benth. and Gymneia Benth., the 

others being already occupied. Apart from the large number of changes proposed for many New World 

species, there are also a number of weedy species introduced into the Old World tropics which are affected: 

Hyptis suaveolens (L.) Poit. and Hyptis pectinata (L.) Poit. become Mesosphaerum suaveolens (L.) Kuntze 

and M. pectinatum (L.) Kuntze respectively, and Hyptis mutabilis (Rich.) Briq. becomes Cantinoa mutabilis 

(Rich.) Harley & J.F.B.Pastore. Hyptis spicigera Lam. takes up the earlier Aublet epithet, which could not be 

used under Hyptis, to become Cantinoa americana (Aubl.) Harley & J.F.B.Pastore. Other species, such as 

Hyptis brevipes Poit., H. lanceolata Poir. and H. capitata Jacq., remain unchanged. 

The following text provides a provisional key to genera, a conspectus of Hyptidinae, with descriptions 

and new combinations, where needed. The establishment of the new classification and nomenclature is a 



priority and opens up the need for a more detailed search for characters which may prove to be diagnostic of 

the newly recognized genera, beyond those already used. Also, a number of species, which have been difficult 

to obtain, still require analysis to confirm their taxonomic position, although their absence does not affect the 

overall taxonomy and these are listed in the conspectus as “unplaced”. Within Hyptis (sensu stricto) much 

wider sampling is still required to evaluate infrageneric groupings and this is a task for the future. A list of 

Hyptidinae, with original names, the pre-1950 taxa as recognized by Epling, with their new taxonomic 

position, is provided (Appendix 1). Bibliographic references indicate where accepted names were published, 

if these occurred prior to this paper, and names which contain a new epithet are also listed. Epithet changes 

which only involve a change of gender are not provided.

† Note on the capitulum: In Hyptidinae, the flowers are arranged in a diverse array of forms. Especially in Hyptis sensu 

stricto, the flowers form a spherical or hemispherical capitulum. The flowers are sessile or almost so (pedicel less than 

0.5 mm) and borne on a slightly swollen receptacle and surrounded by an involucre of linear to ovate bracteoles, which 

are not associated with the individual flowers. Some other groups, such as in the genus Cantinoa, the flowers are often in 

congested cymes or capituliform heads, usually fewer-flowered and with a numerical relationship between flowers and 

bracteoles, but the heads are not spherical or hemispherical in form. See other note on capitulum structure, under 

Cyanocephalus. 



Conspectus of Hyptidinae with new classification including new combinations, synonyms and 

typifications 

Asterohyptis Epling (1932: 17). Type:—Asterohyptis stellulata (Benth.) Epling (1932: 17) ≡ Hyptis stellulata 

Bentham (1833: 129). 

This genus, which is the only one of the tribe which does not occur in South America, has the flowers 

arranged in elongate, spike-like inflorescences, composed of few-flowered verticillasters, in axils of reduced 

bracts. The calyx lobes are subulate or filamentous, often rigid, spreading, corollas small, white, weakly 2lipped 

with 5 subequal lobes and lacking the explosive pollination mechanism, with the thickened hinge at 

base of anterior corolla lip. The three or possibly four species (Turner 2011) extend from Mexico to Central 

America, in dry, open habitats. See Fig. 2B.

This subsectional name is illegitimate, being a superfluous name for Hyptis subsection Vulgares. Epling 

(1933) mentions it only in his account of N American Hyptis, subsequently ignoring the name.

J.F.B.Pastore]. 

Cantinoa is a genus composed of herbs, subshrubs or shrubs with often aromatic, mesomorphic leaves, 

sessile to long-petiolate. The flowers are borne in congested 12−26-flowered, ± ovoid cymes (cymules), not 

forming hemispherical or spherical capitula, the flowers subsessile and surrounded by rather slender to ovate, 

sometimes scarious bracteoles apparently equal in number to the flowers and sometimes investing them to 

form an involucre. The calyx has a straight tube with five usually subequal ± subulate lobes, these rarely 

absent or reduced, the corolla with well-developed, spreading limb. Gynoecium without stylopodium. The 

cymules often form branched synflorescences or may be congested to form ± oblong, terminal spikes. There 

are 23 species currently recognized, extending from SE United States to the Caribbean and S America as far 

as Argentina, and occurring in a variety of mostly mesophytic habitats. Two species are widespread and have 

been introduced into the Old World: Cantinoa americana (Aubl.) Harley & J.F.B.Pastore is frequent in the 

tropics as a weed of cultivation, and C. mutabilis (Rich.) Harley & J.F.B.Pastore has been recorded from S 

Africa. See Fig. 2D. 

Epling (1949) recognized five subsections under Hyptis sect. Polydesmia. Of these, Hyptis subsects. 

Oocephalus and Glomeratae have here been placed in another genus, Oocephalus (Benth.) Harley & 

J.F.B.Pastore. Hyptis subsect. Malvastra, was erected by Epling (1936b) solely on the basis of the presence of 

dendroid hairs, but it can no longer be upheld, as these have now been found to occur in other species, e.g. C. 

carpinifolia (Benth.) Harley & J.F.B.Pastore (of subsect. Rigidae Benth.). Hybrids have now been recognized 

involving C. mutabilis (H. subsect. Vulgares) with both C. carpinifolia (H. subsect. Rigidae) and C. 


HARLEY & PASTORE

althaeifolia (Pohl ex Benth.) Harley & J.F.B.Pastore (H. subsect. Malvastra). As a result there now seems 

little justification in maintaining these subsections at any rank. 

The genus is named in honour of Dr Philip Cantino, Ohio, whose researches on Lamiaceae, especially the 

delimitation of its suprageneric taxa and his studies on the distinguishing characters between this family and 

the Verbenaceae, have greatly advanced our understanding of the group.

The original Aublet specimen, presumably from French Guiana, has not been found. However he cites the 

above polynomial and plate from the earlier Plumier volume, which enables the choice of Plumier’s plate as 

lectotype, although this was an illustration of a specimen from the Antilles, without further indication of 

provenance. To assist identification of the name we also propose an epitype, designated here: MEXICO.

In the protologue, after the species epithet, Bentham (1833) added “Martius MSS” in parenthesis, and he 

clearly referred to a specimen he saw in Munich (only). Epling (1936b) lectotypified Hyptis racemulosa with 



the Martius duplicate at Kew (Epling 1936b: 243), saying that he could find no specimen either at M nor in the

The genus Condea is characterized by an often spiciform or raceme-like thyrse of pedunculate or sessile 

cymes in which the intercalary cyme-axes are contracted. When cymes pedunculate, the flowers, which often 


HARLEY & PASTORE

ear long pedicels, appear subumbellate, or appear fasciculate when peduncle absent. Flowers usually small, 

gynoecium without stylopodium. There are 26 species, ranging from North America (One species in the 

western United States) and Central America to the Caribbean and South America. 

The genus is divided into two sections here, which correspond to three sections recognized by Epling 

under Hyptis (1949). Condea sect. Condea is exactly equivalent to H. sect. Minthidium, while H. sect. 

Umbellatae Epling is placed in synonymy under C. sect. Laniflorae (Epling) Harley & J.F.B.Pastore.

Condea section Condea is characterized by an indumentum of simple trichomes and with flowers solitary 

or in fascicles, in the axils of reduced or leaf-like bracts. In some species, the nutlets bear a swollen, corky 

swelling, which may act as a flotation device to aid dispersal. There are 16 species, centred in the Caribbean 

and in South America, with one species, Condea verticillata, more widespread, occurring in the Caribbean, 

Central America and western South America. See Fig. 1K.

Condea undulata (Schrank) Harley & J.F.B.Pastore, comb. nov. ≡ Hyptis undulata Schrank (1822: 51−52). 

Type:—BRAZIL. A plant formerly cultivated in the Munich Botanical Garden, now apparently lost. Neotype 

designated here: BRAZIL. São Paulo: Parque do Estado, Instituto de Botânica, 26 March 2004, Cordeiro & 

Harley 2805 (HUEFS!). 

Schrank cultivated Hyptis undulata from seeds collected by Martius in Brazil, but apparently failed to 

keep a herbarium specimen. The name was included by Bentham, in the synonymy of the protologue of 

Hyptis fasciculata, with a question mark, and the short description fairly clearly indicates its 

identity.Unfortunately this means a change from the well-known name of this species. 

= Hypothronia undata Schrank (1824: 85). Type:—NOT LOCALIZED. Neotype designated here: BRAZIL. 

Santa Catarina: Garuva, 2 May 2008, Harley 55879 (HUEFS!). 

The generic name Hypothronia was treated as doubtful by Bentham (who used the spelling Hippothronia) 

and by Epling, both of whom placed it in synonymy. The generic name is based on Hypothronia undata, 

which was published simultaneously. (It is possible that this is a misprint for Hyptis undulata Schrank, 

published a few years earlier). As is the case with many Schrank names, H. undata was probably based on a 


HARLEY & PASTORE

cultivated specimen, and no type material has ever been located. The description given by Schrank is difficult 

to relate to any particular taxon, although both Bentham (1833: 130) and Epling (1949: 156) place this 

tentatively in the synonymy of Hyptis fasciculata [= Condea undulata]. Following their opinion, we accept 

that Hypothronia undata Schrank, may well be this, and have chosen a neotype to that effect. 

= Clinopodium verticillatum Vellozo (1829: 242) [nec Condea verticillata (Jacq.) Harley & J.F.B.Pastore]. 

Type:—BRAZIL. Rio de Janeiro: Fl. Flumin. Icon. 6: t. 4. (1831), lectotype designated here [the original plate 

on parchment of "Flora Fluminensis" is in the Manuscript Section of the Biblioteca Nacional of Rio de 

Janeiro]. Epitype designated here: BRAZIL. Santa Catarina: Garuva, Sol Nascente, 9 May 1981, Hatschbach 

43874 (MBM; isoepitypes C!, K!, MU). 

The epitype is to establish the identity of Vellozo’s name as Condea undulata. It is impossible to 

determine which species was intended from the illustration, which could equally well have been either C. 

undulata or C. fastigiata. 

= Hyptis fasciculata Bentham (1833: 130), syn. ≡ nov. Mesosphaerum fasciculatum (Benth.) Kuntze (1891: 

516).�Type:—BRAZIL. "Brasilia meridionalis", Sellow 2030 (holotype B†; lectotype K!, designated here). 

Bentham published this name in the protologue as: “174. H. FASCICULATA (Benth: in Herb. Mus. Reg. 

Berol. MSS.)” Bentham travelled widely in Europe and visited many herbaria, annotating specimens. The 

holotype, now destroyed, was therefore in Berlin. 

= Hyptis fasciculata Benth. var. tomentella Bentham (1848: ≡ 129) Hyptis fasciculata var. tomentosa Schmidt 

(1858: 142). Type:—BRAZIL. Minas Gerais: “circa João Gomes”, Pohl 3768 (holotype W!). 

Bentham apparently indicated a specimen from Minas Gerais for this variety by putting the words: 

“specimina magis tomentosa” after it. The same reference can be found also in his earlier work (Bentham 

1833: 130), in which he cites the full locality, but without providing a name.

Condea urbanii Harley & J.F.B.Pastore, nom. nov. ≡ Hyptis escobilla Urban 1919: 143, nom. illeg. (excl. syn. 

Satureja americana Poir.). Type:—DOMINICAN REPUBLIC. Santo Domingo: Puerto Plata, 16 April 1887, 

Eggers 1545 (lectotype K!, designated here; isolectotypes BM!, G!, M!, P!). 

Although Hyptis escobilla Urb. is an illegitimate and superfluous name because the protologue included 

Satureja americana Poir. in synonymy, it is not typified by the type of S. americana (≡ Condea americana) 

because Urban designated a different type (Art. 7.5 of the Vienna Code, McNeill et al. 2006). Moreover 

Urban’s description as well as the type appears to belong to a previously undescried taxon, which now 

requires a new name. The specimen of Hyptis escobilla in Urban’s own herbarium at B was obviosuly 

destroyed, and so we have selected a lectotype from K. 

In spite of Urban’s description, the apparent lack of ripe fruit, both in the type material and other 

collections cited by Epling, raises the possibility that this might be a hybrid with Condea americana as one of 

the parents.

Type:—MEXICO. Guaymas: without locality, 1885, Palmer 278 (holotype GH; isotypes BM!, C!, K!, US!). 

Epling (1949) cited as type of Hyptis emoryi an early Emory collection, now in the NY herbarium, from 

the same general locality (near Yuma), but this does not accord with the protologue. In an earlier paper, Torrey 

(1858) had erroneously named the Emory material Hyptis lanata, citing Bentham (1844a: 42). This must be 

an error for Hyptis laniflora Benth., which is the only Hyptis species from Baja California mentioned in that 

publication. Although the Emory collection is actually H. emoryi, the specimen cited in the protologue is the 

Newberry specimen, as given above. Hyptis lanata Pohl ex Bentham (1833) is an earlier legitimate name for a 

Brazilian species.

Epling clearly intended that Hyptis rugosa Benth. should be the type of this subsection (Epling 1936b). 

However the subsectional name was published three years earlier (Epling 1933) with only one species cited: 

the Cuban Hyptis pedalipes, which therefore automatically becomes the type.

Benth. [= Cyanocephalus lippioides (Pohl ex Benth.) Harley & J.F.B.Pastore]. 

Cyanocephalus is composed of herbs and subshrubs, often strongly aromatic, with usually small leaves, 

entire or toothed to deeply pinnatifid. It is distinguished by its pedunculate capitula, globose even when 

immature, with narrowly linear, soft bracteoles (see note), which form an involucre, inconspicuous at anthesis, 

the calyx with linear, usually clavate lobes, with an oblique throat and tube usually down-curved to deflexed, 

above the middle. Gynoecium without stylopodium, style capitate, with stigmatic branches usually reduced. 

The sectional classification presented by Epling (1949) has proved unusable (Harley, 2006). There are 25 

species currently recognized, mainly found in the cerrados of central Brazil, extending to eastern Paraguay 

and Bolivia. The type species is endemic to Cuba. See Fig. 1D, F. 

Note:—The bracteolar nature of the involucres of the Hyptidinae capitulum can be demonstrated by a 

study of the structure of congested inflorescences in a number of species with less compact inflorescence 

units, where the flowers and bracteoles subtending them become reoriented, the flowers moving to an upper 

position related to the inflorescence axis, and the bracteole to a lower position, with foreshortening of the axes 

separating them (cincinnus or drepanium).

In the protologue Bentham does not mention a specimen at K, as he normally did. In this case he merely 

states: “Hab. in Brasilia: in campis desertorum ad Rio Parahybuna provinciae Minas Gerais, Pohl! (v.s.sp. in 

herb. Mus. Caes. Reg. Bras. Vind.)”. Bentham travelled widely in Europe, visiting many herbaria, whose 

specimens he annotated, and sometimes received duplicates of material at a later date.

As indicated by the extensive synonymy and the number of varieties which have been recognized, the 

species is morphologically extremely diverse. Epling (1949) recognized three varieties, but subsequent 

collections make these of doubtful value. A full study is required to determine the status of these forms.

Eplingiella Harley & J.F.B.Pastore, gen. nov. Hyptidendro similis sed gynoecio sine stylopodio, et corollis 

forma propria lobis patentibus azureo-violaceis coloratis, et ab omnibus generibus Hyptidinarum 

combinatione foliiorum parvorum xeromorphorum et floribus brevemente pedicillatis in cymulis plusminusve 

paucifloribus bracteolatis, bracteolis parveolis inconspicuis, calycibus fructificantibus aut actinomorphis lobis 

curtis fauce barbato trichomatibus albis aut zygomorphis tubo ad medium deflexo, fauce non barbato, lobis 

subulatis haud clavatis differt. Type:—Eplingiella fruticosa (Salzm. ex Benth.) Harley & J.F.B.Pastore [= 

Hyptis fruticosa Salzm. ex Benth]. 

This genus is characterized by its shrubby habit, with small xeromorphic leaves, the flowers in 2−18flowered 

pedunculate cymes, subtended by bracts similar to leaves, of shortly pedicellate flowers with small, 

inconspicuous, narrowly linear bracteoles. Corolla characteristic, with spreading lobes, blue to violet-blue. 

Fruiting calyx variable, that of E. cuniloides actinomorphic with short lobes and with dense white trichomes 

in throat and E. fruticosa zygomorphic, with mid-tube strongly curved and lobes subulate, not clavate and 

throat not bearded. Gynoecium without a stylopodium, style capitate or with stigmatic lobes very short. 

Nutlets narrowly ellipsoid, dark brown, strongly mucilaginous when wet. 



There are two species at present recognized, from semi-arid, sandy areas in the upland interior of Northeast 

Brazil, the type species descending to coastal sands and the other endemic to Morro do Chapéu, Chapada 

Diamantina, Bahia. See Fig. 3C. 

Both species of Eplingiella were originally included by Epling (1936b) in Hyptis sect. Umbellaria, 

together with a group of other species, later removed to Hyptidendron sect. Umbellaria (Harley 1988), and 

characterized by the possession of a well developed stylopodium. Lacking this feature, the two species 

mentioned above remained unranked for a number of years, as they did not appear to fit in any of the sections 

of Hyptis recognized at that time. The molecular analysis, presented by Pastore et al. (2011), has shown that 

they form a distinct clade and justifies their recognition at generic level. The genus is named in honour of Carl 

Epling, whose contribution to the study of the New World Lamiaceae is immense.

Trees, shrubs or subshrubs, often aromatic; stems often geoxylic, sometimes virgate, often with 

conspicuous white, spreading setose hairs and a few species as in Hypenia with pruinose, fistulose internodes 

below inflorescence. Inflorescence elongate, raceme-like, simple or branched, with 1-flowered pedunculate 

cymes from the axils of caducous bracts, the peduncle appearing as a pedicel (pseudo-pedicel), but with a pair 

of usually inconspicuous bracteoles at its apex, at base of calyx. Calyx turbinate to campanulate, 5-lobed, the 

posterior lobes often becoming connate and indistinct in fruit, when throat closed by dense white hairs in 

many species; corolla strongly 2-lipped, violet or pink and often yellowish in bud, tube widening above and 

sometimes dorsally gibbous, usually constricted near base, posterior lip internally with dark striae and a 

whitish area at base. Gynoecium with conspicuous persistent stylopodium overtopping ovary. Nutlets slightly 

flattened to ovoid, rarely narrowly winged. 

There are over 30 species occurring in savannas, especially cerrados of Central Brazil and in campo 

rupestre in mountain areas of Eastern Brazil, and in campinas in Amazonia, with a few species extending into 

neighbouring countries. See Fig. 2E. 

Harley (1976) revised the genus, raising the number of species recognized by Epling (1936) from 18 to 

20, by various taxonomic changes, reducing several to synonymy, describing four new species and 

transferring three species from Hyptis. Later (Harley 1992) further changes and additions were made. 

Eriopidion Harley (1976: 103) ≡ Eriope sect. Tubiflorae Epling (1936a: 190). Type:— Eriopidion strictum 

(Benth.) Harley [= Eriope stricta Bentham (1848: 142)]. 

The only species is a low perennial herb, sometimes slightly woody at base, strongly aromatic. It shares 

many of the characters found in species of Eriope, including the slender raceme-like inflorescence composed 

of 1-flowered cymes, but differs in the persistent bracts, the narrowly campanulate calyx with a broad 

hygroscopic posterior lobe, which folds when dry to close mouth of calyx, a gynoecium with stylopodium 

absent and with ±triquetrous nutlets. 


HARLEY & PASTORE

A monotypic genus (Harley 1976), with Eriopidion strictum a rare plant of dry, sandy areas within the

Gymneia is composed of herbs or subshrubs, characterized by terminal inflorescences of elongate, 

congested or interrupted spikes, with flowers arranged in ± globose verticillasters in the axils of reduced 

bracts, the verticillasters formed of strongly congested cincinni with filiform bracteoles. Flowers with corollas 

small, fruiting calyx with strongly curved tube and oblique mouth, gynoecium without stylopodium, style ± 

capitates, stigma lobes much reduced. A very homogeneous genus of at least six species, occurring in the 

cerrados of central Brazil, with one species occurring in waste places in the caatingas of NE Brazil and 

disjunctly in eastern Bolivia, where it may have been introduced. See Figs. 2A, 3A.

Hypenia (Mart. ex Benth.) Harley (1988: 91) ≡ Hyptis sect. Hypenia Mart. ex Bentham (1833: 136). 

Type:—Hypenia reticulata (Mart. ex Benth.) Benth. [= Hyptis reticulata Mart. ex Benth., lectotype designated 

by Epling 1936b]. 

The genus is composed of shrubs or subshrubs of virgate habit, usually slightly aromatic, with erect, 

virgate stems and with at least the upper internodes pruinose, fistulose and sometimes slightly inflated, lower 

stems often with conspicuous white, spreading setose hairs. The inflorescence lax or congested and composed 

of 1-flowered cymes, rarely 3-flowered, the peduncle appearing as a pedicel, but with a pair of narrow and 



inconspicuous or broad, persistent bracteoles at base of calyx. In many species the peduncles are elongate and 

very slender, while others have short peduncles and congested inflorescences. Calyx subactinomorphic, 

campanulate to tubular and distinctly 5-lobed with subequal lobes; corollas pale blue, lilac, red or yellow, 

small with short tube, to large, and then with elongate tube, tube usually contracted near base and with 

relatively short lobes; gynoecium with a very short stylopodium, much shorter than the ovary; nutlets ovoid. 

The species with a lax inflorescence of large red corollas, many of which have resupinate flowers (Atkinson, 

unpublished thesis), appear to be adapted to bird pollination, and are often visited by humming-birds. 

The genus, with ca. 23 species, is typical of the upland lateritic savannas or cerrados and the shallow 

sandy soils of the campo rupestres in Goiás and the Serra do Espinhaço range of Eastern Brazil, extending to 

eastern Paraguay and Bolivia, with one species widespread in the caatingas of NE Brazil and with records 

from the Guayana Highlands of Venezuela. See Figs. 4C, E. 

Harley (1988) erroneously published the combination Hypenia durifolia (Epling) Harley. The correct 

name should be based on the earlier Hyptis sclerophylla Epling, which is illegitimate under that genus.

The molecular data (Pastore et al. 2011) place this species as sister to the rest of Hypenia. This position is 

confirmed by an examination of the gynoecium structure, where the stylopodium is very small or absent, as in 

Hypenia and unlike that in Eriope where it overtops the nutlets. The species was originally removed from 

Hyptis to Eriope (Harley 1988), due to the similarity of its corolla, which bears a remarkable likeness to those 

of the latter genus.

= Hyptis sect. Siagonarrhen Mart. ex Bentham (1833: ≡ 133) Hyptis sect. Siagonarrhen subsect.�Cymosae 

Bentham (1848: 133). Type:—Hyptis scabra Benth., lectotype designated by Epling 1936b [= Hyptidendron 

canum (Benth.) Harley]. 

= Hyptis sect. Latiflorae Epling (1936a: 224), syn. nov. Type:—Hyptis eximia Epling. 

The genus is composed of trees, shrubs or subshrubs, of varied habit, with an indumentum on leaves and 

stems of simple to in some species dendroid hairs, and with small to often large, coriaceous, sometimes 

aromatic leaves. The inflorescence is composed of thyrsoid, often paniculate flowers arranged in dichasial or 

monochasial cymes in the axils of usually foliar bracts, these sometimes conspicuous with white or purplish 

hairs. The pedicellate flowers have inconspicuous bracteoles, and an actinomorphic to weakly zygomorphic 

calyx with tube cylindrical to infundibuliform, straight, 5-lobed with subequal lobes; corollas bluish purple to 

lilac or rarely white, the tube cylindrical to infundibuliform; gynoecium with stylopodium overtopping ovary; 

nutlets ovoid to slightly flattened or narrowly winged. 

The genus contains about 18 species, all occurring in S America from the Guayana Highlands and the 

Andes to Central Brazil, Bolivia and Paraguay. Several species are small trees or shrubs in the cerrados of 

Central Brazil (Harley 1988), and H. arboreum Benth.) Harley can grow up to 20 m high in relictual montane 

forests in Northern and Western S America. See Figs. 1C, E. 


HARLEY & PASTORE

Molecular studies (Pastore et al. 2011) indicate that Hyptis eximia Epling, placed by Epling in a 

monotypic section Latiflorae, falls within this genus, making the following new combination necessary. The 

molecular data shows some conflict with the subsections recognized by Harley (1988). Until fuller data are 

available, it is proposed not to recognize them here. 

Hyptidendron eximium (Epling) Harley & J.F.B.Pastore, comb. nov. ≡ Hyptis eximia Epling (1936a: 223). 

Type:—BRAZIL. Mato Grosso: Barão de Melgaço, June 1918, Kuhlmann 2279 (holotype UC!). 

Hyptis Jacquin (1787a: 101), nom. cons. (Briquet 1906). Type:—Hyptis capitata Jacq., typ. cons. (lectotype 

designated by Green 1929: 107). 

Hyptis Jacq. was conserved against Condea Adans. and Mesosphaerum P.Browne. However the types of these 

two genera no longer fall within our concept of Hyptis, so the names again become available. 

A genus of annual or perennial herbs, subshrubs, or shrubs, of variable habit, with flowers in pedunculate 

to sessile, cymose capitula with an involucre of bracteoles, and borne singly in the axils of foliaceous or 

reduced bracts and sometimes forming complex synflorescences. Flowers usually small, with narrow, 

cylindrical calyx, often accrescent in fruit, usually with subequal lobes; corolla small often white or 

occasionally lilac and with spotted posterior lip, tube cylindrical; Nutlets ovoid or narrowly ellipsoid. 

A genus of around 144 species, distributed in tropical and subtropical zones from North America to the 

Caribbean and southward to Argentina and Peru, often occurring in humid savannas. A few species extend to 

the Old World tropics, mainly as weeds. See Figs. 1H, 2C, 3B, 3D, 4G. 

The molecular studies (Pastore et al. 2011) on which the taxonomic changes provided in this paper are 

largely based, require a much reduced genus Hyptis. Of the 26 sections previously recognized by Epling 

(1949), only ten remain, with a few, such as Hyptis sections Induratae and Pachyphyllae now shown to fall 

within H. sect. Eriosphaeria Benth. Hyptis sect. Polydesmia, partially dismembered, and a sister group to the 

reduced Hyptis clade, is now treated at generic level as Cantinoa and includes several species formerly in H. 

sect. Mesosphaeria. The genus Peltodon is shown to be grouped within Hyptis. There are still questions to be 

answered with respect to inter-relationships within this remodelled Hyptis, but it is hoped that future studies, 

with much wider sampling, will enable a reevaluation of its infrageneric classification. The ten sections of 

Hyptis remaining, which need further investigation, are: Hyptis sect Hyptis, H. sect. Pusillae Epling, H. sect. 

Hilaria, H. sect. Cyrta, H. sect. Plagiotis Benth., H. sect. Myriocephala Benth., H. sect. Muellerohyptis Briq., 

H. sect. Xylodontes, H. sect. Apodotes Benth. and H. sect. Eriosphaeria. The only changes we propose at this 

time are as follows: 

Hyptis section Peltodon (Pohl) Harley & J.F.B.Pastore, comb. & stat. nov. ≡ Peltodon Pohl (1827: 66). 

Type:—Peltodon radicans Pohl, lectotype designated by Epling 1936b [= Hyptis radicans (Pohl) Harley & 

J.F.B.Pastore]. 

Epling (1936b) wrote: “A genus scarcely separate from Hyptis and coordinate with its sections”—a 

comment confirmed by the molecular data (Pastore et al. 2011). 

Hyptis sect. Peltodon is easily recognized by the small, spreading, foliaceous appendage at the apex of 

each calyx lobe. The flowers are arranged in robust, subglobose capitula, with a conspicuous involucre of 

broad, often coloured bracteoles. 

Five species are known, mainly occurring in cerrado or other similar savanna formations or in margins of 

Atlantic forest, in eastern and southern Brazil extending into eastern Paraguay and Argentina. See Fig. 1H.

lectotype designated by Epling 1936b [= Leptohyptis macrostachys (Benth.) Harley & J.F.B.Pastore]. 

An easily recognized genus, of slender shrubs bearing elongate, slender spikes of sessile cymes, 

distinguished especially by the delicate triangular scale in the sinus between each lobe of the calyx, and by the 

slender, tubular corollas with short lobes. 

There are five species, mostly restricted to drier montane areas of NE Brazil, in Bahia, Pernambuco and 

Minas Gerais. See Figs. 1L, 4D. 

Leptohyptis calida (Mart. ex Benth.) Harley & J.F.B.Pastore, comb. nov. ≡ Hyptis calida Mart. ex Bentham

Marsypianthes Mart. ex Bentham (1833: 64). Type —Marsypianthes hyptoides Mart. ex Bentham (1833: 64), 

nom. illeg. [= Marsypianthes chamaedrys (Vahl) Kuntze]. 

Subshrubs or perennial herbs, glandular-viscid, sometimes geoxylic with membranous leaves and axillary, 

few- to many-flowered cymes from the axils of foliar bracts, cymes either pedunculate with a lax sub-globose 

cluster of many flowers subtended by elliptic-lanceolate to linear bracteoles or sessile and 1- to few-flowered. 

Flowers pedicellate, calyx actinomorphic, broadly infundibuliform, with equal ±deltate to lanceolate lobes, 

connivent to erect at first, often becoming spreading to strongly reflexed in fruit; corolla bluish lilac or pale 

yellow, with tube cylindrical and with anterior lobe much shorter than the others; gynoecium with a persistent, 

thickened and angled stylopodium which is fused throughout its length to the inner face of the four ovary 

lobes; on ripening, the four mericarps (nutlets) break free and have a domed outer surface and a concave inner 

surface with a thin laciniate involute margin. The gynoecial structure is unique within the family, the shed 

nutlets strongly resembling minute tortoises! 

Marsypianthes contains about five species, primarily in cerrado, in Central, West and Northeast Brazil, 

extending to Paraguay and Argentina. M. chamaedrys (Vahl) Kuntze is a very polymorphic herb or subshrub, 

mainly of disturbed ground extending from Mexico and the Caribbean, southwards to Peru, Bolivia and N 

Argentina. Species limits in the genus still remain to be clearly defined. See Fig. 3F. 

Martianthus Harley & J.F.B.Pastore, nom.et stat. nov. ≡ Hyptis sect. Leucocephala Bentham (1848: 89) [non 

Leucocephala Roxburgh (1832: 612): Eriocaulaceae]. Type:— Martianthus leucocephalus (Mart. ex Benth.) 

Harley & J.F.B.Pastore [= Hyptis leucocephala Mart. ex Benth.]. 

The genus Martianthus bears flowers in compact, globose, pedunculate capitula with an involucre of 

narrowly linear, membranous bracteoles, obscured when the capitulum matures. The fruiting calyx tube is 

usually curved downward, from the middle, and the gynoecium has no stylopodium. These same 

morphological characters are shared with Cyanocephalus. Martianthus differs from the latter genus, in its 

non-clavate calyx lobes, the corolla lobes are usually very dark vinaceous or purple, sometimes dark pink, 

especially at the apex, with a paler tube and the stigma is usually distinctly lobed, rather than capitate. There 

are four species, three restricted to the caatingas or dry montane semi-arid areas of Northeast Brazil, with an 

outlying species in similar semi-arid conditions in Huarochi, coastal Peru. (On the other hand, the genus 

Cyanocephalus is a characteristic component of cerrado, a seasonal vegetation type centred in Central Brazil). 

See Fig. 4B.

[= Medusantha crinita (Benth.) Harley & J.F.B.Pastore]. 

Medusantha is a small, rather homogeneous group, easily recognized by the flowers in globose capitula, 

with an involucre of soft, filiform bracteoles and the flowers with calyx tube straight, and long filiform calyx 

lobes (hence “medusoid”—Epling 1936b), a very slender corolla tube and a gynoecium without a 

stylopodium, style capitate with stigmatic branches reduced. Butterflies are strongly attracted to at least some 

of the species. There are eight species, mostly occurring in the cerrados of central Brazil. Medusantha 

martiusii is a characteristic shrub of the caatinga vegetation in semi-arid areas of the Brazilian North-east. See 

Fig. 4A.

There are two Sellow specimens of Medusantha crinita in K. Epling erroneously annotated the wrong 

specimen as isotype of Hyptis crinita, as this sheet clearly says “Hyptis crinita ß Benth.” in Bentham’s hand. 

This refers to Hyptis crinita var. ß polycephala Benth., foliis minoribus magis tomentosis, capitulis numerosis. 

The specimen clearly matches this description and is here taken as holotype of this variety. It is the other 

Sellow specimen in K, which is here designated as a replacement lectotype of the typical variety.

Bentham (1833: 127). Type:—Hyptis pectinata (L.) Poit. [= Mesosphaerum pectinatum (L.) Kuntze]. 

Bentham (1833) included only one species, H. pectinata, in his Hyptis section Pectinaria, which was 

reduced to a subsection of sect. Mesosphaeria by Epling (1936b), with seven other species and later expanded 

to 14 (Epling 1949). 

= Hyptis sect. Mesosphaeria subsect. Eriocephalae Epling (1936b: 246). Type:—Hyptis eriocephala Benth. 

[= Mesosphaerum eriocephalum (Benth.) Harley & J.F.B.Pastore]. 



Mesosphaerum, as delimited in this paper, is characterized by an inflorescence with several to many 

flowers usually in lax or more congested cincinnate, pedunculate, sometimes weakly capitate cymes, flowers 

shortly pedicellate, subtended by small bracteoles not forming an involucre, and with a subactinomorphic 

calyx, often with white hairs in the throat, and the gynoecium without a stylopodium. There are about 25 

species, with a primarily Andean distribution, extending also into the mountains of Central America and 

Mexico. Mesosphaerum sidifolium (including Hyptis umbrosa Salzm. ex Benth.) has a wider distribution, 

extending also into eastern Brazil, while M. irwinii is endemic to the mountains of Bahia, Northeast Brazil. 

Two species, M. pectinatum and M. suaveolens, have become common weeds, widespread in the tropics and 

extending into the Old World. See Fig. 2F. 

Epling (1949) originally recognized 32 species in Hyptis sect. Mesosphaeria, divided into five 

subsections: Eriocephalae Epling (14 species) largely Andean, Spicaria (Benth.) Epling (two species), 

Pectinaria (Benth.) Epling (c. 14 species, including two pantropical weeds. H. pectinata (L.) Poit. and H. 

suaveolens (L.) Poit.), and two monotypic subsections Ocimoideae Epling and Plectranthodon Epling. The 

molecular evidence (Pastore et al. 2011) demonstrates that sect. Mesosphaeria is polyphyletic, comprising at 

least two different lineages. One of these, composed of species of Hyptis sect. Mesosphaeria subsect. 

Pectinaria pro parte, subsect. Spicaria and subsect. Plectranthodon has now been included here in the newly 

recognized genus Cantinoa, along with former members of Hyptis sect. Polydesmia. Cantinoa is shown from 

molecular studies to be sister to Hyptis sensu stricto. The other lineage, which comprises Hyptis sect. 

Mesosphaeria subsect. Pectinaria pro parte, including H. pectinata and H. suaveolens, and Hyptis sect 

Mesosphaeria subsect. Eriocephalae, is here recognized as the genus: Mesosphaerum P. Browne. No attempt 

at this stage, has been made to recognize sections within Mesosphaerum, especially as there is still doubt how 

these will eventually be disposed. Indeed the monotypic Hyptis subsect. Ocimoideae remains to be analysed. 

Wider sampling of the constituent species is needed. 

In the list below, we have included all species considered definitely to belong to the genus Mesosphaerum. 

The necessary combination for twelve of the species had already been made by Kuntze (1891).

The specimen at K is numbered 44, but appears to be the same collection. Epling (1933, 1949) gives 

Volcan Viejo as from Costa Rica, but this is erroneous, as Oersted refers to Nicaragua in the protologue. There

There is a specimen of Mesosphaerum pectinatum at M, possibly collected by Martius, which might 

represent the living plant from which H. nepetoides was described, which was said to have come originally 

from Brazil. There is, however, insufficient information available on the sheet. Schrank often did not preserve 

dried material of the cultivated plants to which he gave names, and therefore many of these have not been 

unequivocally identified. It is therefore necessary to choose a neotype.

HARLEY & PASTORE

This species is extremely variable especially in leaf morphology and indumentum. Fernández-Alonso 

(1995) has placed Hyptis silvestris in synonymy of “Hyptis sidifolia”, as it differs primarily in leaf 

indumentum and peduncle length, and after careful study we have accepted this, as these characters occur 

individually in material from other parts of the range of H. sidifolia. For fuller details on synonymy of this 

species see Harley (2006).

Oocephalus oppositiflorus (Schrank) Harley & J.F.B.Pastore [= Hyptis glomerata Mart. ex Schrank, lectotype 

designated by Epling 1936b]. 

Shrubs or subshrubs, rarely herbs with usually small or medium-sized leaves, sessile or shortly petiolate, 

distinguished by the possession of an inflorescence of congested, pedunculate or sessile cymes, few- to manyflowered, 

not forming a globose or semi-globose capitulum, but ± ovoid in form, enveloped by an involucre of 

usually broad, ovate or lanceolate bracteoles, especially in bud, rarely narrower and not enveloping the cymes. 

Flowers sessile or subsessile, corollas with an elongate tube, lobes usually short. Gynoecium without 

stylopodium. 14 species are recognized here, typically in campo rupestre of the Serra do Espinhaço of Minas 

Gerais and Bahia and in similar habitats in Goiás. One species, O. oppositiflorus, is spreading through Brazil 

into disturbed habitats and has a wider distribution, extending into eastern Bolivia. Further research is needed 

to define more clearly the characters of the genus. See Figs. 1A, 4H.

The bracteoles of this species are atypical for the genus, in being very slender and not enveloping the 

flowers. However Rudall (pers. com. in Harley 1986a) has demonstrated the very characteristic leaf anatomy 

which places this species unequivocally with the genus Oocephalus, confirmed by the molecular results.

The type locality has not been traced. The greater part of the the Rio Tocantins is in Tocantins State 

(formerly a part of Goiás) though a part of the upper reaches of the river extend into Goiás State. The only 

extant population known is in the Chapada dos Veadeiros, Goiás.

Unfortunately, the earliest name for this species is that of Schrank, which supersedes the well-known 

epithet of “glomerata”. The cultivated plant on which the current name is based was grown from seed 

collected in Brazil by Martius, but no specimen appears to exist. 

Oocephalus pauciflorus (Harley) Harley & J.F.B.Pastore, comb. & stat. nov. ≡ Hyptis halimifolia Mart. ex

NY!, SPF!, U!, UEC!, US!). 

Field observations and study of the substantial number of collections of both this taxon and of Oocephalus 

halimifolius indicate that they are morphologically quite distinct and have differing altitudinal ranges and 

ecological requirements and are therefore best treated as distinct species.

instructis et basi calycis bracteolis binatis destituto differt. Type:—Physominthe vitifolia (Pohl ex Benth.) 

Harley & J.F.B.Pastore [= Hyptis vitifolia Pohl ex Benth]. 

Shrubs or subshrubs, often aromatic; stems virgate, erect, upper internodes glabrous, pruinose, usually 

strongly fistulose and inflated, nodes and lower stems often with long, rigid setose hairs; leaves lobed, 

sometimes weakly so; inflorescence thyrsoid, lax, formed of pedunculate, subumbellate, few-flowered cymes 

(with intercalary axes reduced), 3- to 6-flowered, flowers shortly pedicellate from the axils of minute, 

subulate bracts; flowers small with calyx ± actinomorphic, turbinate at anthesis, becoming ± campanulate in 

fruit, bracteoles reduced, when present borne near base of cyme, never paired at base of calyx, style deciduous 

from below nutlets, stylopodium absent. 

Similar, in its virgate habit with upper internodes inflated, glabrous and pruinose, to Hypenia, in which it 

was formerly included, and some species of Eriope, and differing from all species of both these genera in 

lacking a pair of bracteoles at base of calyx. Chromosome number 2n = 28, differing from numbers found in 

Eriope (2n = 20) and Hypenia (2n = 20, 12). See Harley & Heywood (1992). The genus is restricted to upland 

cerrado areas of Bahia, Minas Gerais, Goiás and São Paulo. One species so far described with another 

awaiting publication. See Figs. 1B, 3E.

= Hyptis sect. Xanthiophaea Bentham (1833: 70. Type:—Hyptis sideritis Mart. ex Benth., lectotype 

designated by Epling (1936a: 186). 

Epling excluded two of the three species which Bentham recognized in Hyptis Sect. Xanthiophaea. 

However he misspelt the genus as Raphiodon, a name frequently encountered in herbaria. 

Rhaphiodon is a monotypic genus, with R. echinus the only species. It is a prostrate, aromatic herb, with 

flowers in long-pedunculate spherical heads, with spinose involucral bracteoles and the calyx with lobes 

composed of up to ca 11 spines, corolla long-tubular, bright purple, the spinose fruiting head, with only one 

nutlet per flower, falling as a unit. It occurs in seasonally damp, disturbed areas, especially along roadsides in 

the caatingas of Northeast Brazil extending southwards to N Minas Gerais State. See Figs. 1G, 3G. 

Sections unplaced to genus 

Hyptis sect. Rhytidea Epling (1933: 80), with two species, H. rhytidea Bentham (1839: 21) and H. 

pseudolantana Epling (1941: 553), may possibly belong in Condea Adans. Hyptis rhytidea was shown to be 

sister to the Condea clade (Pastore et al. 2011). Further studies are needed to explore this relationship. 

Hyptis sect. Hilaria Epling (1936b: 280). Type:—Hyptis lobata A.St.-Hil. ex Bentham (1833: 97). A 

monotypic section, which is only known from the type: BRAZIL. São Paulo: São José dos Campos? [São 

Jozé], Saint-Hilaire 664 (holotype P!; isotype F!). This species may well be related to Hyptis lagenaria A.St.- 

Hil. ex Bentham (1833: 98), in Hyptis sect. Cyrta, but further material is needed to establish its correct 

position.

(CAPES, PDEE) for financial support for the second author’s Doctoral programme and also the staff of the 

Departamento de Ciências Biológicas of the Universidade Estadual de Feira de Santana (UEFS), Brazil and 

the Keeper and staff of the Herbarium and Library of the Royal Botanic Gardens, Kew, UK for providing 

facilities and much assistance. We would also like to thank the staff of the many herbaria, cited in the text 

above, and visited mostly by the senior author over many years, for permission to use their facilities, their 

welcome and assistance. Thanks are especially due, in RBG Kew, to Alan Paton, Gemma Bramley, Lesley 

Walsingham for constant help or advice, and to the staff of the IPNI office, especially Irina Belyaeva, and also 

to Dick Brummitt, for guidance over nomenclatural matters. We particularly wish to acknowledge the great 

help given to us by John McNeill over Condea urbanii, which caused us quite a few headaches. We also wish 

to thank Alan Paton, Henrique Moreira, Domingos Cardoso and Sergio Bordignon for permission to use some 


HARLEY & PASTORE

of their images of Hyptidinae. Those not acknowledged were taken by the authors. The study visit by the 

senior author to the University Herbarium of Copenhagen helped resolve a number of problems. Support was 

made available by the European Community–Research Infrastructure Action under the FP6 Structuring the 

European Research Area Programme (grant DK-TAF-1865). We would like to thank Hajo Esser, of the 

Botanische Staatssammlung, Munich, for editorial guidance and valuable advice, on Roxburgh’s Clinopodium 

repens and many other matters. Also we should like to thank the two reviewers who, with their constructive 

criticism, ensured a much better final product, and finally we thank especially Ana Maria Giulietti for 

constant advice, encouragement and support at all stages of the preparation of this paper.
