Ab stra ct : Gemmabryum J.R.Spence & H.P.Ramsay is considered to be congeneric with two
monotypic South American moss genera, Neobryum R.S.Williams and Osculatia De Not., of which
the latter has priority. It is the earliest available generic name for one of the largest segregates
of the broadly conceived genus Bryum Hedw. which consists of some 44 species disposed in three
sections that have a worldwide distribution. Traditionally, they were all placed in Bryum or
Brachymenium Schwägr. and the relevant transfers to Osculatia are effected in the present account.

Introduction
Along with Mnium Hedw., Phascum Hedw., Splachnum Hedw., Sphagnum L. and Hypnum
Hedw., Bryum Hedw. is a generic name known from antiquity. It comes from a Greek
designation for moss which was used by Dioscorides for some cryptogams and subsequently
applied by Dillenius (1741) to this genus and its relatives. It was the largest moss genus
recognised by this author who placed in it some 83 species which were given polynomial names.
The name Bryum was widely used in all botanical works in the eighteenth century and it was
accepted by Linnaeus (1753) in his Species plantarum, an opus which for nearly 160 years
served as a starting point for the nomenclature of mosses. It was changed at the Third
International Botanical Congress, held in 1910 in Brussels, when Hedwig’s (1801) Species
muscorum frondosorum was accepted as a new starting point for Musci (except Sphagnaceae)
(Briquet 1912).
Hedwig (1801) validated the generic name Bryum and published 11 binomials for various
species which are considered to be only distantly related in modern classifications of mosses.
In the subsequent four decades Bryum served as an all-encompassing genus in which various
acrocarpous species had been placed, often not having much in common with this genus in its
present circumscription. Conversely, for some species which have later been considered to be
incontestable members of Bryum, separate genera had been established, including
Ptychostomum Hornsch. (Hornschuch 1822) and Cladodium Brid. and Hemisynapsium Brid.
(Bridel 1826) but they have not gained acceptance and have fallen into obsolescence.
The first attempt to refine the concept of the genus Bryum was undertaken by Bruch et al.
(1839) in Bryologia europaea, but in its species composition it corresponded rather to the family Bryaceae in its widely accepted circumscription. The modern concept of Bryum was
outlined by Schimper (1856) in Corollarium Bryologiae europaeae and developed in his
Synopsis muscorum europaeorum (Schimper 1860). It was generally accepted by bryologists,
with some minor modifications in subsequent decades when some species placed in this genus
were split off into separate small genera, including Anomobryum Schimp. (Schimper 1860),
Epipterygium Lindb. and Plagiobryum Lindb. (Lindberg 1863), Argyro-bryum Hampe (Hampe
1876), Argyrobryum (Müll.Hal.) Kindb. (Kindberg 1882, 1883) and Rhodobryum (Schimp.)
Limpr. (Limpricht 1892). Most of these segregates have gained wide acceptance and have been
universally used in Floras, checklists and catalogues of mosses.
71
In its traditional circumscription Bryum is one of the largest and morphologically diverse
of moss genera. Brotherus (1924) included in it about 800 species distributed worldwide but
this number has been significantly reduced as a result of revisionary taxonomic studies.
Nonetheless, there exists a remarkable discrepancy among various researchers regarding
the current number of Bryum species. Ochi (1992) stated that approximately 150 species are
still residual in this genus, whilst according to Spence’s (2014) calculations this number is about
twice as large.
As is the case with many large and heterogeneous moss genera, Bryum has been divided
into numerous infrageneric taxa which often pose various nomenclatural problems (Ochi 1992;
Isoviita 1992). In the last two decades, the tendency to divide large and heterogeneous moss
genera is clearly marked, the traditionally understood genus Bryum being split into a number
of segregates on the basis of morphological (Spence 1996, 2005, 2007, 2009a, b; Pedersen
2000; Spence & Ramsay 2005, 2006) and molecular data (Pedersen 2000; Pedersen & Hedenäs
2002, 2003, 2005; Pedersen et al. 2003, 2007; Holyoak & Pedersen 2007). Accordingly,
the forgotten genus Ptychostomum was resurrected from obsolescence (Spence 2005a) and
some new segregates have been recognised, namely Leptostomopsis J.R.Spence & H.P.Ramsay
and Plagiobryoides J.R.Spence (Spence 2005a), Gemmabryum J.R.Spence & H.P.Ramsay and
Ochiobryum J.R.Spence & H.P.Ramsay (Spence 2005b), and Imbribryum N.Pedersen
(Pedersen & Hedenäs 2005; Pedersen 2005).
There are no fewer than four neglected names which were used for exotic monotypic genera
of the Bryoideae, including Peromnion Schwägr., Streblopilum Ångstr., Osculatia De Not. and
Neobryum R.S.Williams. We have evaluated their availability as potential candidates for older
correct names of the aforementioned segregates of Bryum.
Taxonomic history of Peromnion and Streblopilum
The oldest of these forgotten generic names is Peromnion Schwägr. which was used for
a genus erected by Schwägrichen (1828) for the Brazilian species P. radiculosum Schwägr. This
genus was subsequently accepted by Hornschuch (1840) but Mitten (1869) reduced it to
a section of the then all-encompassing genus Bryum in which he placed four South American
species. A year later Hampe (1870) transferred Peromnion radiculosum to the genus
Brachymenium Schwägr. as B. radiculosum (Schwägr.) Hampe and he repeated this taxonomic
concept in his subsequent paper on Brazilian mosses (Hampe 1879). Additionally, he reduced
Peromnion to an unranked subdivision of the genus Brachymenium Schwägr. This taxonomic
concept of Peromnion was accepted by Brotherus (1903, 1924) who recognised Peromnion as
one of four sections of Brachymenium, B. sect. Peromnion (Schwägr.) Broth. which is obviously
typified by Brachymenium radiculosum (Peromnion radiculosum), the type of the monotypic
genus Peromnion (Art. 7.3 of the current Code) (Turland et al. 2018).
Ochi (1980) introduced serious confusion in the infrageneric classification of Brachymenium because he placed B. radiculosum in the type section of the genus, while for sect.
Peromnion he designated B. jamesonii Taylor [=B. speciosum (Hook.f. & Wilson) Steere] as
a lectotype. From the nomenclatural point of view this operation cannot be accepted because
the transfer of the type species of sect. Peromnion automatically makes this section name
a heterotypic synonym of the type section. For the emended sect. Peromnion in which Ochi
(1980) placed five neotropical species, a new name should be devised. This group is certainly
not homogeneous and, as Spence (2014) rightly noted, it is similar to some species of
Gemmabryum. Indeed, three species placed in sect. Peromnion sensu Ochi (1980) are actually
members of the latter genus. However, sect. Peromnion in the strict sense, typified by
Brachymenium radiculosum, has nothing in common with this genus but its type is a typical
representative of Brachymenium.
72
It is characterised by its rosulate, not comose and gemmiform stem with subfloral
innovations, spathulate leaves twisted and appressed to the stem on drying, long-excurrent costa
as a smooth arista, and clavate, obloid-clavate to cylindrical capsules with a short, slender neck,
over 3 mm long, and a short conical and bluntly apiculate to hemispherical operculum.
The genus Streblopilum Ångstr. was established by Ångström (1876) to accommodate
a single Brazilian species, Brachymenium regnellii Hampe. The author considered it to be
closely related to and intermediate between Brachymenium and Peromnion, but no definite
diagnostic characters were provided. This monotypic genus can be well diagnosed by the traits
of the type species, which is charactectised by its erect, cylindrical, elongate capsule, about
5 mm long, with a long-beaked and blunt operculum and a costa which vanishes well below
the leaf apex in the lower leaves and is percurrent to short-excurrent in the upper leaves.
The overall appearance of the plants and leaves fits the genus Brachymenium well, so Streblopilum does not deserve recognition as a genus in its own right. Bescherelle (1891) described
Brachymenium spirale Besch. from Paraguay and indicated its close similarity to B. regnellii.
In fact he placed this species in an unranked infrageneric taxon Streblopilum. Although no
description of this taxon is given, B. regnellii, the generitype of Streblopilum, is mentioned in
the discussion and according to Art. 41.3 of the ICN (Turland et al. 2018) it may be considered
as an implicit reference to the genus Streblopilum and Bescherele’s (1891) parenthetic citation
of Streblopilum within Brachymenium may be accepted as a new combination. Thus, Streblopilum cannot be considered a candidate for a name of any aforementioned segregate of Bryum,
but it is worth noting that this name could be used for sect. Peromnion sensu Ochi (1980) if it
truly deserves taxonomic recognition.
Taxonomic history of Osculatia and Neobryum
Osculatia is the third neglected and obscure genus of the exotic bryalean mosses. It was
described by De Notaris (1859) from the specimen collected by Gaetano Osculati (18081894),
an Italian naturalist and traveller, in the drainage basin of the Napo River in northern South
America. The paper in which De Notaris (1859) described and illustrated a number of new
species from the collection of Osculati was carefully analysed by Steere (1988) who found it
puzzling in some points. It proved that most probably it had appeared as a preprint in 1858, as
such a copy is available in the Mertz Library in the New York Botanical Garden. Additionally,
due to the lack of detailed locality data, it is impossible to indicate the exact loci classici
of the newly described taxa which apparently originated either from Ecuador or Peru.
De Notaris (1859) placed the newly erected genus Osculatia in the Meesiaceae on account
of the overall similarity of the capsules and leaves of its only species O. columbica De Not. to
those of Catoscopium Brid. This refers especially to the nearly horizontal spherical capsules
with a hemispherical and nearly conical operculum and rigid lanceolate leaves with a salient
costa excurrent as a short arista. Osculatia columbica and other species described by De Notaris
(1859) were ignored by Mitten (1869) and the species was only listed by Jaeger (1875) and
Jaeger and Sauerbeck (1879) in Adumbratio florae muscorum and later by Paris (1896) in Index
bryologicus.
Salmon (1902) was the first to re-examine the type of Osculatia columbica and he found
this species to be conspecific with Bryum globosum Mitt., a species described by Mitten (1869)
from the Andes of Ecuador. He paid special attention to the peristome of this species and pointed
out that it perfectly matches the peristome of Brachymenium which he considered as a section
of the broadly conceived Bryum. This concept was subsequently accepted by Brotherus (1903,
1924) who placed Osculatia in synonymy with Brachymenium and classified B. columbicum
(De Not.) Broth. in the sect. Dicranobryum (Müll.Hal.) Broth.
Ochi (1980) was not aware of Salmon’s (1902) study but he examined the type of Bryum
globosum Mitt., which is an illegitimate later homonym of B. globosum Lindb. and in
73
Brachymenium it bears the name Brachymenium globosum A.Jaeger. He established a separate
section, Brachymenium sect. Globosa Ochi, for this species and he placed, with a question
mark, Osculatia columbica in synonymy with Brachymenium globosum, mainly because he had
not studied any original material of that taxon. According to Ochi (1980) this species may be
a link between Pohlia Hedw. and Brachymenium and a characteristic feature of it is the presence
of bulbous, yellow axillary gemmae. This is a medium-sized plant with well-spaced, longdecurrent, imbricate-flexuose leaves which are very variable in shape, ranging from ovate or
ovate-lanceolate to elongate-triangular. The leaf margins are entire to obscurely crenulate and
are usually weakly bordered by 1-2 rows of narrow, elongate cells. The costa is strong, reddish
and excurrent as a stout cusp. The capsules are globose and the peristome has highly modified
segments and cilia. The true segments are actually absent, as in most other species of Brachymenium, but the cilia are fully united and on either side fused with portions of segments and
this entire structure is positioned opposite the exostome teeth (Shaw 1984). This is a remarkable
expression of peristome morphology, yet it is a fundamentally bryoid one and in terms of other
characters Brachymenium columbicum is quite firmly rooted in that genus in its classical
circumscription.
Brachymenium columbicum is a widespread neotropical species and its geographical range
extends from southern Mexico (Campeche and Tabasco) (Ochi 1994) and the Caribbean (Cuba,
Dominican Republic and Puerto Rico) (Delgadillo et al. 1995), through Central America
(Guatemala, Costa Rica and Panama) (Allen 2002) to South America (Colombia, Venezuela,
Ecuador, Peru, Bolivia, Brazil) including the Galapagos Islands (Delgadillo et al. 1995). In this
wide range it was described several times as a separate species (see Robinson 1967; Ochi 1992,
1994; Allen 2002 for synonyms). One of its synonymous names is Neobryum costatum
R.S.Williams, a species described from Colombia (Williams 1925). It was erected on the basis
of its peristome which is typical of B. columbicum as described above, otherwise Neobryum is
a genus close to Bryum. Therefore Robinson (1967) considered Neobryum and Osculatia
congeneric.
Because gametophytically, especially in its vegetative propagation by axillary gemmae,
Brachymenium columbicum matches well the concept of the genus Gemmabryum, in our
opinion Osculatia is the oldest generic name for this segregate of the broadly conceived Bryum.
Accordingly, Gemmabryum is considered congeneric with Osculatia.
