Four new species, M. anomalocarpa, M. chiangraiensis, M. gardneri, and M. maxiflora, are described. Meiogyne anomalocarpa has the widest distribution of any Meiogyne species in Thailand, but the other three species are narrowly distributed. Meiogyne anomalocarpa and M. maxiflora have the axillary inflorescences typical of the genus, but in M. chiangraiensis and M. gardneri the inflorescences are flagelliform and arise from the lower trunk, a morphology previously unreported from members of this genus. The presence of M. chiangraiensis in northern Thailand extends the range of the genus significantly northward. Meiogyne caudata is reported as new to the flora of Thailand. Several Meiogyne specimens from southernmost Thailand previously identified as M. virgata in the past by various workers were found to be more similar to M. kanthanensis, recently described from Perak, Peninsular Malaysia. A key is provided for the eight species currently recognized as occurring in the country.

SP - 106659 KW - Annonaceae KW - diversification rates KW - Liana KW - Pollination trap KW - Seed dispersal KW - Traits AB - A major goal of phylogenetic systematics is to understand both the patterns of diversification and the processes by which these patterns are formed. Few studies have focused on the ancient, species-rich Magnoliales clade and its diversification pattern. Within Magnoliales, the pantropically distributed Annonaceae are by far the most genus-rich and species-rich family-level clade, with c. 110 genera and c. 2,400 species. We investigated the diversification patterns across Annonaceae and identified traits that show varied associations with diversification rates using a time-calibrated phylogeny of 835 species (34.6% sampling) and 11,211 aligned bases from eight regions of the plastid genome (rbcL, matK, ndhF, psbA-trnH, trnL-F, atpB-rbcL, trnS-G, and ycf1). Twelve rate shifts were identified using BAMM: in Annona, Artabotrys, Asimina, Drepananthus, Duguetia, Goniothalamus, Guatteria, Uvaria, Xylopia, the tribes Miliuseae and Malmeeae, and the Desmos-Dasymaschalon-Friesodielsia-Monanthotaxis clade. TurboMEDUSA and method-of-moments estimator analyses showed largely congruent results. A positive relationship between species richness and diversification rate is revealed using PGLS. Our results show that the high species richness in Annonaceae is likely the result of recent increased diversification rather than the steady accumulation of species via the ‘museum model’. We further explore the possible role of selected traits (habit, pollinator trapping, floral sex expression, pollen dispersal unit, anther septation, and seed dispersal unit) in shaping diversification patterns, based on inferences of BiSSE, MuSSE, HiSSE, and FiSSE analyses. Our results suggest that the liana habit, the presence of circadian pollinator trapping, androdioecy, and the dispersal of seeds as single-seeded monocarp fragments are closely correlated with higher diversification rates; pollen aggregation and anther septation, in contrast, are associated with lower diversification rates.

A molecular phylogenetic analysis of this group was undertaken using maximum parsimony, maximum likelihood and Bayesian methods based on four chloroplast DNA regions (matK, psbA-trnH spacer, rbcL and trnL-F). The resultant trees were moderately well resolved with significant statistical support for most nodes. Uvaria is shown unequivocally to be paraphyletic, with all representatives of the other five genera nested within it. The distinguishing morphological characteristics of the related genera are re-evaluated, and interpreted as no more than specialised adaptations of the basic Uvari structure. The generic names Anomianthus, Cyathostemma, Ellipeia, Ellipeiopsis and Rauwenhoffia are accordingly reduced to synonymy with Uvaria, necessitating 11 new nomenclatural combinations and four replacement names.

Although Polyalthia has recently been reduced in taxonomic scope, the remaining species in the genus still form a phylogenetically disparate and morphologically heterogeneous assemblage. We use maximum parsimony, maximum likelihood and Bayesian phylogenetic reconstructions based on chloroplast DNA sequence data (matK, rbcL, trnL-F) to show that the remaining Polyalthia species segregate into three clades: a clade sister to Miliusa; a clade that also includes all Enicosanthum and Woodiellantha species sampled, sister to Neo-uvaria; and a clade that also includes all Haplostichanthus species sampled, inferred (based on previous research) to be sister to Popowia. Diagnostic morphological and anatomical characters are evaluated for the latter two clades, and diagnostic leaf and seed characters identified. Based on these results, the generic name Monoon is resurrected for the clade that includes Enicosanthum and Woodiellantha, following the transfer of 37 species from Polyalthia s.l., 18 species from Enicosanthum and the single Woodiellantha species. The generic name Haplostichanthus is furthermore synonymised with Polyalthia s.str., necessitating nine nomenclatural changes, including six new combinations and three replacement names.

The undigested part forms a central binder holding the four microspores of the tetrad together. This process causes the microspores to rotate 180 degrees. In this paper we describe pollen formation in another annonaceous genus, Cymbopetalum, in which the pollen is shed in octads, through use of light microscopy, epifluorescence microscopy, and TEM. In Cymbopetalum, two meiocytes, connected by abundant cytomictic channels, are produced in each sporangium. Octad pollen formation in Cymbopetalum is shown to be comparable to the synchronized formation of two connected Annona tetrads, which then integrate into a single octad. Unique features of Annona polyad formation, e.g. special binding between the callose-cellulose envelopes and microspores, incomplete callose digestion, and microspore rotation, also occur in Cymbopetalum. In addition, formation of the Cymbopetalum octad involves development of a cushion-like structure that binds the distal pronexine of all eight microspores, and there is the production of intine protrusions. The evolutionary origin of the callose-cellulose binding mechanism within the family is discussed. VL - 263 SN - 0378-2697 JO - Pl. Syst Evol.

We present a detailed discussion of morphological characters used in a combined morphological and molecular phylogenetic analysis of Anaxagorea, along with implications of the analysis for character evolution in the genus. In spite of a high level of homoplasy in stamen and leaf venation characters, their removal results in loss of resolution in the trees obtained. The distributions of characters on trees confirm assumptions that several distinctive similarities between Anaxagorea and other Magnoliales are primitive retentions (e.g., the presence of an arlaxial plate of xylem in the midrib, nonpeltate stamen connectives, inner staminodes, and several leaf architectural characters). However, lateral extensions of the "laminar" stamens, though possibly ancestral in Anaxagorca, are convergent with those in other Magnoliales. A number of morphological synapomorphies have been identified for a clade containing most Central American species and another comprising all Asian species (e.g., conical bud shape and reduced inner petals for the Central American clade, and arlaxial cuticular striations and capitate stigma shape for the Asian clade).

MECOCARPUS KW - GUATTERIELLA KW - GUATTERIOPSIS KW - Neotropics AB - This paper deals with a group of species of the Neotropical genus Guatteria (Annonaceae) which are characterized by leaves with tiny warts (verruculae) on both surfaces and by elongate and short-stipitate monocarps (i.e., the length of the monocarp body surpassing the length of the stipe). These species were placed by Fries in Guatteria sect. Mecocarpus (Fries 1939) (the name derives from Ancient Greek μηκων = Poppy and καρπος = fruit: fruit resembling that of Papaver species). All occur in South America, none having been found elsewhere so far. Although there is much doubt nowadays about the taxonomic significance of Fries's sections, we maintain sect. Mecocarpus at present for convenience's sake. Additionally, the former genus Guatteriopsis, united with Guatteria a short time ago (Erkens & Maas 2008b), is now also included in sect. Mecocarpus. The same applies to one of the two species attributed to Guatteriella (also merged with Guatteria by Erkens & Maas 2008b), namely Guatteriella tomentosa R.E.Fr. (not Guatteria tomentosa Rusby) which is put into synonymy with Guatteria trichocarpa Erkens & Maas. One new species is described, namely Guatteria griseifolia Maas & Westra. The two species complexes of G. guianensis and G. decurrens are now treated each as a single polymorphic species. The present study falls within the framework of a planned monograph of the whole genus Guatteria.

Examples are given of species pollinated by beetles (cantharophily), which is the predominant mode of the majority of species worldwide, by small or large beetles (both groups having either diurnal or nocturnal flowers with or without thermogenesis), species pollinated by thrips (Thysanoptera), flies (myiophily and sapromyiophily), cockroaches and even bees (melittophily). Adaptational features of floral structures are compared with the behaviour of flower visitors, emphasizing floral rhythm, flower size, petal thickness, stamen structure and odour production. Anaxagorea, the earliest divergent surviving genus in Annonaceae, exhibits floral characters thought to be basal for the family: tissue-rich thick petals that form a pollination chamber; several Anaxagorea spp. exhibit thermogenesis, emit a fruit-like odour and attract small beetles as pollinators. As cantharophily is plesiomorphic in Anaxagorea and in Annonaceae, characters associated with beetle pollination appear imprinted in members of the whole family. Even non-cantharophilous species retain one or more characteristic features of beetle-pollinated species, such as thick petals, flattened and sclerified connective shields or protogynous dichogamy. © 2012 The Linnean Society of London, Botanical Journal of the Linnean Society, 2012, 169, 245–261.

Phylogenetic analyses of eight chloroplast regions (matK, ndhF, ndhF-rpl32, psbA-trnH, rbcL, rpl32-trnL, trnL-F, and ycf1; ca. 9.2 kb, 66 taxa) unambiguously placed D. saccopetaloides in a subclade of tribe Miliuseae, nested among the genera Monoon, Neo-uvaria, Phaeanthus, Sageraea, and Stelechocarpus. This relationship was also supported by endosperm rumination patterns in the seed; other morphological characters furthermore indicated that D. saccopetaloides has closer affinities with Monoon, Neo-uvaria, and Phaeanthus rather than either Sageraea or Stelechocarpus. Desmos saccopetaloides is distinguished from these genera by its leaf-opposed inflorescences, sepaloid outer petals, saccate inner petals with basal glandular tissue, moniliform monocarps with uniseriate seeds, and rectangular disulculate pollen with two “cryptoapertures”. On the basis of the combined molecular phylogenetic and morphological data, we propose a new genus, Wangia, to accommodate D. saccopetaloides. The molecular phylogenetic analyses furthermore indicated that Desmos yunnanensis belongs to the genus Dasymaschalon: examination of the type collections revealed that it is conspecific with Dasymaschalon obtusipetalum, although the combination Dasymaschalon yunnanense has nomenclatural priority.

Guatteria (Annonaceae) is, with 265 species, the third largest genus of Neotropical trees after Inga (Fabaceae) and Ocotea (Lauraceae), and its widespread distribution and frequent occurrence makes the genus an excellent model taxon to study diversification patterns. This study reconstructed the phylogeny of Guatteria and inferred three major biogeographical events in the history of the genus: (1) a trans-oceanic Miocene migration from Central into South America before the closing of the Isthmus of Panama; (2) a major diversification of the lineage within South America; and (3) several migrations of South American lineages back into Central America via the closed Panamanian land bridge. Therefore, Guatteria is not an Amazonian centred-genus sensu Gentry but a major Miocene diversification that followed its dispersal into South America. This study provides further evidence that migration into the Neotropics was an important factor in the historical assembly of its biodiversity. Furthermore, it is shown that phylogenetic patterns are comparable to those found in Ocotea and Inga and that a closer comparison of these genera is desirable.

SP - 133 EP - 159 KW - Annonaceae KW - cladistics KW - EVOLUTION KW - GENERA KW - Magnoliales KW - palynology KW - phylogeny KW - SYSTEMATICS KW - ULTRASTRUCTURE AB - Phylogenetic analyses based on morphology place Anaxagorea and other taxa with granular monosulcate pollen, as in other Magnoliales, at the base of Annonaceae. Taxa with columellar tetrads, granular tetrads, and inaperturate monads form a derived clade. To test the systematic importance of palynology, we analyzed the data set with pollen characters removed. The result was lower resolution and a different rooting of the family, between Uvariopsis and other groups with columellar tetrads. Anaxagorea and other monosulcates are higher in the tree, implying that granular monosulcate pollen, laminar stamens, and irregular endosperm ruminations are reversals. This rooting is highly unparsimonious when pollen characters are included, and only weakly supported over the Anaxagorea rooting when pollen is excluded. Together with preliminary molecular analyses, these experiments confirm the special value of palynology in systematics of Annonaceae. VL - 206 JO - Pl. Syst Evol.

Examples are given of species pollinated by beetles (cantharophily), which is the predominant mode of the majority of species worldwide, by small or large beetles (both groups having either diurnal or nocturnal flowers with or without thermogenesis), species pollinated by thrips (Thysanoptera), flies (myiophily and sapromyiophily), cockroaches and even bees (melittophily). Adaptational features of floral structures are compared with the behaviour of flower visitors, emphasizing floral rhythm, flower size, petal thickness, stamen structure and odour production. Anaxagorea, the earliest divergent surviving genus in Annonaceae, exhibits floral characters thought to be basal for the family: tissue-rich thick petals that form a pollination chamber; several Anaxagorea spp. exhibit thermogenesis, emit a fruit-like odour and attract small beetles as pollinators. As cantharophily is plesiomorphic in Anaxagorea and in Annonaceae, characters associated with beetle pollination appear imprinted in members of the whole family. Even non-cantharophilous species retain one or more characteristic features of beetle-pollinated species, such as thick petals, flattened and sclerified connective shields or protogynous dichogamy. © 2012 The Linnean Society of London, Botanical Journal of the Linnean Society, 2012, 169, 245–261.

A molecular phylogenetic analysis of this group was undertaken using maximum parsimony, maximum likelihood and Bayesian methods based on four chloroplast DNA regions (matK, psbA-trnH spacer, rbcL and trnL-F). The resultant trees were moderately well resolved with significant statistical support for most nodes. Uvaria is shown unequivocally to be paraphyletic, with all representatives of the other five genera nested within it. The distinguishing morphological characteristics of the related genera are re-evaluated, and interpreted as no more than specialised adaptations of the basic Uvari structure. The generic names Anomianthus, Cyathostemma, Ellipeia, Ellipeiopsis and Rauwenhoffia are accordingly reduced to synonymy with Uvaria, necessitating 11 new nomenclatural combinations and four replacement names.

Very few studies have however been conducted in important tropical centers of plant biodiversity like the African rainforests. The phylogeography of a tree species widespread in Central African mature forests, Greenwayodendron suaveolens subsp. suaveolens (Annonaceae), was investigated in the Lower Guinea phytogeographic domain (essentially Gabon and Cameroon) by sequencing an intergenic spacer of the chloroplast genome (trnC-petN1R). A total of 11 polymorphic sites, including nine single nucleotide polymorphisms (SNPs), two insertions/deletions and two inversions, defined 12 haplotypes. The taxon is represented by two sympatric varieties (var. suaveolens and var. gabonica) that carried distinct and relatively divergent haplotypes. These varieties, also well distinguishable morphologically, might therefore represent true biological species. The variety suaveolens, more common and more widespread than the variety gabonica, was represented by ten haplotypes. This taxon showed a weak but statistically significant phylogeographic structure, indicating that two sets of related haplotypes essentially occurred respectively in the northern and the southern hemispheres. These results suggest that the distribution of Greenwayodendron suaveolens subsp. suaveolens, which is currently continuous in the Lower Guinea domain, might have been more fragmented in the past, possibly in relation with Pleistocene forest fragmentation.
