Enlarging the Madagascan genus Fenerivia

INTRODUCTION
The genus Polyalthia Blume (Annonaceae) was first estab-
lished by Blume (1830) following the transfer of species names
from Unona L. f. and Guatteria Ruiz & Pav. Although only five
species were initially recognised in the genus, over 300 species
names have subsequently been published within the genus (In-
ternational Plant Names Index, IPNI: http://www.ipni.org/), of
which approximately 150 names are currently accepted (Global
Index of Annonaceae Names: http://herbarium.botanik.univie.
ac.at/annonaceae/listTax.php). Polyalthia is therefore currently
one of the largest genera in Annonaceae.
Polyalthia has been described as a “default genus which is
defined only by the absence of conspicuous synapomorphies”
(Johnson & Murray, 1999), and this has resulted in it effec-
tively becoming a “dustbin” genus for many Palaeotropical
Annonaceae taxa of uncertain affinities. The inevitable mor-
phological heterogeneity resulting from this prompted several
authors to suggest that the genus is likely to be paraphyletic or
polyphyletic (Rogstad & Le Thomas, 1989; Van Setten & Koek-
Noorman, 1992; Doyle & Le Thomas, 1994, 1996; Doyle & al.,
2000). The polyphyletic status of the genus has since been
confirmed by Mols & al. (2004a, b), who used combined matK,
rbcL, and trnL-F sequence data to show that Polyalthia species
occur in at least five distinct clades. These clades furthermore
included (or were ambiguously related to) species belonging
to several smaller genera (Enicosanthum Becc., Haplostichan-
thus F. Muell., Marsypopetalum Scheff.), implying that these
genera also need to be incorporated in taxonomic reassessments
of Polyalthia. The unresolved phylogenetic status of the genus
Polyalthia is argu ably the most sig nif icant cu rrent impediment
to Annonaceae systematics research.
Hooker & Thomson (1872) recognised 25 species of Poly-
althia, which they classified in three sections, sect. Polyalthia
(as “Eupolyalthia”), sect. Monoon (Miq.) Hook. f. & Thomson,
and sect. Trivalvaria (Miq.) Hook. f. & Thomson. The latter two
sectional names were based on genera established by Miquel
(1865). Another section, sect. Afropolyalthia Engl. & Diels,
was subsequently added to the genus by Engler & Diels (1901)
for two African species. The taxonomic scope of Polyalthia
was later reduced following: (1) the reinstatement of Trival-
varia (Miq.) Miq. as a distinct genus (Sinclair, 1951; see also
subsequent revision by Van Heusden, 1996); (2) the separa-
tion of Polyalthia sect. Afropolyalthia as the distinct genus
Greenwayodendron Verdc. (Verdcourt, 1969); (3) the transfer
of several Polyalthia species characterized by pollen octads to
Disepalum Hook. f. (Sinclair, 1955) and Enicosanthellum Bân
(Bân, 1975; species subsequently transferred to Disepalum by
Johnson, 1989); (4) the removal of the Southeast Asian “Poly-
althia hypoleuca complex” (sensu Rogstad, 1989, 1990, 1994;
Rogstad & Le Thomas, 1989) as the new genus Maasia Mols
& al. (Mols & al., 2008); and (5) the recent transfer of several
Polyalthia species to Marsypopetalum (Xue & al., 2011).
Although Polyalthia is poorly represented in continental
Africa, the genus appears to be considerably more diverse in
Madagascar. Schatz & Le Thomas (1990) recognized 18 Poly-
althia species in Madagascar, which they classified into five
in formal groups (refer red to as groups A– E). Species in groups
B and C are characterized by sulcate pollen with a columellar
exine (Schatz & Le Thomas, 1990), typical of the “malmeoid”

Abstract
The genus Polyalthia (Annonaceae) has been demonstrated to be polyphylet ic, with the Asian specie s with columellar-
sulcate pollen recently segregated to form a new genus, Maasia. The phylogenetic affinities of the other Polyalthia species
with colu mell ar-sulc at e pollen, which occur in Madagascar, are investiga te d using ma xi mu m parsimony, ma xi mu m likeli ho od
and Bayesian phylogenetic analyses of three chloroplast DNA markers (trnL-F, matK, rbcL). The species are shown to form
a well-supported clade which warrants taxonomic recognition as a distinct genus. The name Fenerivia is adopted, consider-
ably expanding the application of this formerly monotypic name, with nine new nomenclatural combinations validated. The
genus is hypothesised to have undergone a homeotic mutation in which the outermost whorl of stamens develop as inner petals
(presumed andropetals), and the calyx is reduced to a vestigial flange.

Enlarging the Madagascan genus Fenerivia
clade (Doyle & Le Thomas, 1996). In contrast, species in
groups A, D, and E are characterized by inaperturate pollen
with a non-columellar exine (Schatz & Le Thomas, 1990),
typical of many members of the “miliusoid” clade (Doyle & Le
Thomas, 1996). It is noteworthy, however, that some of the mil-
iusoid taxa previously regarded as inaperturate, including Tri-
valvaria (Walker, 1971) and Marsypopetalum s.l. (Mols & al.,
2004a), are now known to be disulculate (Xue & al., 2011), and
that such pollen may be widespread within the mil iu soid clade
(Waha & Hesse, 1988; Waha & Morawetz, 1988; Chaowasku
& al., 2008). The contrasting pollen characteristics of the dif-
ferent Madagascan representatives of Polyalthia suggest that
they are unlikely to be congeneric and that those in groups B
and C may share a closer phylogenetic affinity with Maasia,
which comprises species formerly included in the Polyalthia
hypoleuca complex (Mols & al., 2008). The present research
clarifies the phylogenetic and taxonomic relationships between
Maasia and the Madagascan Polyalthia species with columel-
lar-sulcate pollen, and is based on extensive sampling of spe-
cies from group B (P. angustielliptica Schatz & Le Thomas,
P. chapelieri Baill., P. emarginata Diels, P. madagascarien-
sis Cavaco & Keraudren) and group C (P. capuronii Cavaco
& Keraudren, P. ghesquiereana Cavaco & Keruadren, P. het-
eropetala (Diels) Gesq., P. humbertii Cavaco & Keraudren,
P. oligosperma (Danguy) Diels, P. richardiana Baill.).
Polyalthia heteropetala, a member of group C, was origi-
nally described as the sole representative of the genus Fenerivia
Diels (Diels, 1925). This taxonomically isolated position was
proposed because of the aberrant floral morphology evident in
the only known flowering specimen: unlike the flowers of the
great majority of Annonaceae species, which have a perianth
of nine organs in three whorls (three sepals, three outer petals,
three inner petals), Polyalthia (Fenerivia) heteropetala has a
perianth of 12 organs. The homology of the latter organs has
been the source of some discussion (Diels, 1925; Ghesquière,
1939; Schatz & Le Thomas, 1990; Deroin, 2007), but was inter-
preted by Saunders (2010) to be the result of a disruption to the
homeotic control of organ identity during floral development.
Molecular phylogenetic data is used in the present research to
reassess putative homologies in the floral structure of P. het-
eropetala and related species with columellar-sulcate pollen.
MATERIALS AND METHODS
Taxon sampling. —
The data matrix comprised a total of
123 species of Annonaceae representing all major clades in
the family. The dataset was based on three chloroplast DNA
regions: trnL-F, matK, and rbcL. Novel sequences were gener-
ated for the additional species from Madagascar, including all
Madagascan species of Polyalthia belonging to groups B and
C (sensu Schatz & Le Thomas, 1990), together with additional
Maasia species. The samples, localities, and GenBank acces-
sion numbers are given in the Appendix.
DNA extraction, amplification, and sequencing. —
Total
genomic DNA was extracted from herbarium leaf samples us-
ing a modified cetyl trimethyl ammonium bromide (CTAB)
method (Doyle & Doyle, 1987; Erkens & al., 2008; Su & al.,
2008), with DNA purified using the Wizard PCR Preps DNA
Purification System (Promega, Madison, Wisconsin, U.S.A.),
and eluted with 50 µl preheated TE (Tris-EDTA) buffer.
The following primers were used for amplification: trnL-
F (trnL intron and trnL-trnF intergenic spacer)—primers
trnLF-12F/433R, trnLF-147F/508R, trnLF-413F/724R, and
trnLF-597F/960R (Su & al., 2008); matK gene—primers
matK-13F/515R , matK-424F/788R, and matK-449F/824R (Su
& al., 2008); and rbcL gene—primers rbcL-7F/429R, rbcL-
127F/734R , rbcL-656F/1100R, and rbcL-984F/1381R (Su & al.,
2008).
All PCR reactions were performed in a total volume of
50 µl using 1× PCR buffer, ca. 10 ng DNA, 3 mM MgCl
2
,
0.2 mM dNTP, 0.3 µM of each primer, 2 U Taq DNA poly-
merase (Promega), and 0.5 µg/µl BSA (Promega). The PCR
conditions consisted of 3 min at 94°C, followed by 35 cycles
of 45 s at 94°C denaturation; 30 s at 49°C annealing for trnL-F,
52°C–55°C annealing for matK and rbcL; and 2 min extension
at 72°C; and an additional final extension of 7 min at 74°C. Suc-
cessfully amplified products were purified with the QIAquick
PCR purification kit (Qiagen, Valencia, California, U.S.A.)
following the manufacturer’s instructions.
Sequencing reactions were carried out for both forward and
reverse strands using the same PCR primers, and the BigDye
Terminator v.3.1 cycle sequencing kit (Applied Biosystems,
Foster City, California, U.S.A.). Purified sequencing reactions
were run commercially on an Applied Biosystems 3730XL
DNA Analyzer.
Phylogenetic analyses. —
Sequences were edited and
assembled in SeqMan Pro using DNAStar Lasergene 8.0
(DNAStar, Madison, Wisconsin, U.S.A.), and aligned manually
using BioEdit v.7.0.9 (Hall, 1999) and Se-Al v.2.0a11 (Ram-
baut, 1996). The combined three-region dataset consisted of
3186 aligned characters (trnL-F: 1054 bp; matK: 789 bp; rbcL:
1343 bp) following the removal of 65 bp ambiguously aligned
positions in trnL-F.
Maximum parsimony (MP) analyses of the three com-
bined datasets were conducted using PAUP* v.4.0b10 (Swof-
ford, 2003). All characters were weighted equally and indels
were treated as missing data. The most pa rsimonious trees were
obtained with heuristic searches of 1000 replicates of random-
addition-sequence, tree bisection-reconnection (TBR) branch
swapping, and saving 10 trees from each random sequence
addition. Bootstrap support (BS) values for the nodes were
estimated using 1000 random-addition-sequence replicates
with TBR branch swapping, and 10 trees saved per replicate.
Maximum likelihood (ML) analyses were conducted for
the three-gene dataset using GARLI v.0.95 that implements
a full heuristic tree search (Zwickl, 2006). The best-fitting
nucleotide substitution model was determined by the Akaike
In formation Criterion (AIC) using the MrModelTest v.2.3 (Ny-
lander, 2004). The analyses were performed using a random
starting tree and the ML bootstrap (BS) values were estimated
from 200 bootstrap replicates in GARLI.
Partitioned Bayesian analyses were performed on the
three-gene combined dataset using MrBayes v.3.1.2 (Ronquist

60 (5) • October 2011: 1407–1416
& Huelsenbeck, 2003). Separate models of molecular evolu-
tion for individual gene partitions were determined by Mr-
ModelTest v.2.3 (Nylander, 2004). Four Metropolis-coupled
Markov Chain Monte Carlo (MCMC) runs, each with five
heated chains and one cold chain, were run for 5 million
generations with trees sampled every 100 generations. The
final average standard deviation of the split frequencies was
< 0.01, indicating that the sampling of the posterior distribu-
tion was adequate. The convergence of the MCMC runs was
also compared and checked using the online program AWTY
(Nylander & al., 2008). The output AWTY plot displaying
the posterior probabilities of splits between runs was linear,
indicating that the runs had reached convergence. Effective
sampling size (ESS) and burn-in were estimated using Tracer
v.1.5 (Rambaut & Drummond, 2009); all parameters had ESS
values above 200 and the first 10% of the sampled trees was
discarded. The remaining trees were used to generate a 50%
major ity-rule consensus tree and calculate the posterior prob-
abilities (PP). A more distant outgroup, Anaxagorea silvatica,
was used to root the tree.
RES ULTS
Of the 3186 included characters, 376 bp (11.8%) were
variable but parsimony-uninformative and 438 (13.7%) were
parsimony-informative. Parsimony analysis of the combined
regions yielded 2310 most parsimonious trees of 1463 steps
(consistency index, CI = 0.645; retention index, RI = 0.784;
rescaled retention index, RC = 0.506). For the combined ML
analyses, GTR + I + G was selected as the best-fitting model.
Model parameter values were estimated as follows: base fre-
quencies: A = 0.2885, C = 0.1946, G = 0.2125, T = 0.3043; rate
matrix: A–C = 1.3785, A–G = 2.8460, A–T = 0.6622, C–G
= 0.8091, C–T = 3.4410, G–T = 1.0; proportion of invariable
sites (I) = 0.4708; and gamma shape parameter = 0.9649. The
likelihood score of the optimal ML tree, −InL, was 14,622.2148.
For the mixed-model Bayesian analyses, the best-fit model of
sequence evolution for each gene partition was selected by AIC,
as follows: GTR + G for trnL-F and matK, and GTR + I + G for
rbcL data.
Parsimony, maximum likelihood, and Bayesian analyses
of the combined cpDNA regions consistently recognized four
Polyalthia clades (clades I–IV in Figs 1–2). Clade IV includes
10 Polyalthia species (viz.: P. chapelieri, P. heteropetala,
P. madagascariensis, P. angustielliptica, P. oligosperma,
P. richardiana, P. humbertii, P. ghesquiereana, P. emargi-
nata, P. capuronii). This clade received very strong statisti-
cal support (MP BS = 100%, ML BS = 100%, PP = 1.00;
Fig. 1). Maasia is furthermore shown to form a well-supported
clade (MP BS = 97%, ML BS = 97%, PP = 1.00). Clade IV
shows a relatively rapid average rate of molecular evolution
(Fig. 2), with 0.1533 substitutions per site; this is approxi-
mately 6 times faster than that of clade I (0.024 substitutions
per site) and 2.5 times faster than clade II (0.060 substitutions
per site), but is similar to that of clade III (0.1383 substitutions
per site).
DISCUSSION
The results of the phylogenetic analyses presented here
(Figs 1–2) reveal that the “Polyalthia columellar-sulcate group”
(sensu Doyle & Le Thomas, 1994, 1995, 1996) is represented
by two distinct and well-supported clades: an Asian clade
with five Maasia species; and a Madagascan clade with all 10
Polyalthia species belonging to groups B and C (sensu Schatz
& Le Thomas, 1990). Significantly, the latter clade has never
been recovered in previous molecular phylogenetic analyses of
the family. The phylogenetic relationships of these two “col-
umellar-sulcate” clades are obscured, however, due to lack of
adequate resolution and support. Only one other Madagascan
Polyalthia species was included in the analysis: P. pendula
Capuron ex Schatz & Le Thomas, belonging to group E (sensu
Schatz & Le Thomas, 1990), is shown to be nested within Pol-
yalthia clade III (Fig. 1), together with P. cerasoides (from
Asia), P. stuhlmannii (from continental Africa), and P. korinti
(from Asia). Although Polyalthia species in groups A and D
and those occurring in East Africa were not included in the
present analyses, they are known to be related to species in
Polyalthia clade III based on palynological and macromor-
phological resemblances (Verdcourt, 1969; Vollesen, 1980a,
b; Schatz & Le Thomas, 1990).
It is evident that the newly identified Madagascan clade
of Polyalthia species (clade IV in Figs 1–2) is not congeneric
with Polyalthia s.str. (represented by clade II), and the species
therefore need to be reclassified. The species in Polyalthia
clade IV are furthermore not congeneric with either of the other
Polyalthia clades (I or III), nor any of the other genera which
include species formerly classified in Polyalthia.
One of the species in clade IV, P. heteropetala, was origi-
nally described by Diels (1925) as the type of the monotypic
genus Fenerivia. The name Fenerivia heteropetala was sub-
sequently transferred to Polyalthia (Ghesquière, 1939), and
although this approach was adopted in most later taxonomic
treatments (Cavaco & Keraudren, 1957, 1958; Schatz & Le
Thomas, 1990), others have maintained Fenerivia as a distinct
genus (e.g., Fries, 1959; Van Heusden, 1992; Keßler, 1993).
The recognition of Fenerivia as a distinct genus has recently
received support based on interpretation of floral anatomy
(Deroin, 2007). As the earliest generic name associated with
the species in clade IV, Fenerivia is shown here to be the cor-
rect name for all species in this clade. Nine new nomenclatu-
ral combinations are consequently validated in this paper (see
“Taxonomic treatment” section, below).
Diels (1925) originally segregated F. heteropetala from the
Madagascan Polyalthia species because of its extraordinary
floral structure, with what he interpreted as a highly reduced
calyx of three vestigial sepals, and a corolla consisting of three
broadly ovate outer petals and nine linear inner petals (Fig. 3).
Ghesquière (1939) questioned this interpretation, however,
suggesting that the “calyx” represents an extra-floral nectary,
that the “outer petals” represent the true calyx, and that the
nine “inner petals” actually represent both the inner and outer
whorls of petals (with duplication of one of the whorls). Schatz
& Le Thomas (1990) similarly doubted Diels’ interpretation of

floral structure, but suggested that the calyx (sensu Diels) was
merely an artefact resulting from dehydration of the receptacle.
Deroin (2007) published a detailed anatomical study of
F. heteropetala and argued that Diels’ original interpretation
was correct. He demonstrated that the nine linear petals are of
two types: three bracteopetals, homologous with the inner pet-
als of other Annonaceae species; and six andropetals, derived
from stamens. This was interpreted by Saunders (2010) to be
the result of a substantial disruption of the homeotic control of
floral organ identity during development, with a centrifugal
shift so that the outermost whorl of six stamens develop as inner
petals, the inner petals develop as outer petals, the outer petals
develop to be sepal-like, and the sepals fail to develop sig-
nificantly. Only one f lowering specimen of F. heteropetala is
known (the holotype, H. Perrier de la Bâthie 4942, P) and there-
fore it is not known whether the homeotic mutation occurred
only in this individual (perhaps encouraging de la Bâthie to
collect the sample) or whether the mutation has become fixed
as a characteristic of the species as a whole.
The highly reduced calyx of three vestigial sepals (sensu
Diels) is apparent in all species in the Fenerivia clade, and is
visible in both living plants (Fig. 4A, E) and dried herbarium
specimens, and is noticeably persistent in fruiting material
(Fig. 4B, F). This feature is therefore a valuable character
for distinguishing Fenerivia from other Annonaceae genera
and is a clear synapomorphy for the genus. Deroin (2007)
demonstrated that the flange in F. heteropetala has a va scular
system that is consistent with its interpretation as a calyx,
hence confirming Diels’ view of the flange as a reduced ca-
lyx. Other species transferred here to Fenerivia superficially
have the standard number of petals and sepals for the family
(Fig. 4C, E; Cavaco & Keraudren, 1958) but also possess
the outermost “calyx” flange. Although the homology of the
flange in F. heteropetala and other Fenerivia species has yet
to be unequivocally demonstrated by examining the vascular
supply in the latter, it seems likely that the structures are
equivalent. If this interpretation is correct, the linear petals
of species such as F. angustielliptica (Fig. 4C–E) would pos-
sibly represent two distinct whorls, of mixed bracteopetal
and andropetal origin, consistent with the hypothesis of a
disruption to the homeotic control of organ identity during
floral development; unequivocal interpretation would require
detailed anatomical research to reveal the vascular supply of
the petals, however.

Enlarging the Madagascan genus Fenerivia
On morphological grounds Maasia seems to be the clos-
est relative of Fenerivia, although the relationships revealed
by molecular data remain obscure due to lack of informative
characters. Both genera share a number of characters, including
inconspicuous leaf venation, axillary flowers, ovaries generally
with a single ovule, seeds with a rib-like raphe and spiniform
endosperm rumination, and monosulcate pollen grains with
psilate-perforate ornamentation (Rogstad, 1989; Rogstad & Le
Thomas, 1989; Schatz & Le Thomas, 1990; Mols & al., 2008).
In addition to the presence of the calyx flange as described
above, Fenerivia differs from Maasia in lacking a glaucous
appearance on the abaxial surface of the leaves and in having
significantly larger petals.
The polyphyletic genus Polyalthia has been significantly
reduced in scope in recent years as a result of molecular phy-
logenetic analyses, with the transfer of six species to Maasia
(Mols & al., 2008) and five species to Marsypopetalum (Xue
& al., 2011). The transfer of nine Madagascan Polyalthia spe-
cies to Fenerivia, as proposed here, further reduces the size of
Polyalthia, although it does not render the genus monophyletic.
Further research remains to address the status of Haplostichan-
thus species (associated with the “true” Polyalthia clade II,
inclusive of the type species, P. subcordata) and also the
Polyalthia species associated with Enicosanthum and Miliusa
(clades I and III, respectively).
