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).}, keywords = {adaxial plate, Anaxagorea, Annonaceae, DIVERSITY, HISTORICAL BIOGEOGRAPHY, leaf architecture, Magnoliales, MOLECULES, morphology, PHYLOGENETIC ANALYSIS, PLANTS, stamens, SYSTEMATICS}, author = {Scharaschkin, T. and Doyle, J.

Fourteen species are recognized, including six endemics that are described as new to science (G. acehensis, G. alatus, G. dewildei, G. loerzingii, G. longistaminus and G. miquelianus). In addition, two species are newly recorded from Sumatra, viz. G. parallelivenius Ridl. (previously reported from Borneo), and G. wrayi King (previously reported from Peninsular Malaysia). The extensive nomenclatural confusion regarding the application of the names G. costulatus Miq. and G. opacus Bakh. f. is clarified: the names are shown to be synonymous, with the former having nomenclatural priority. The utility of specific taxonomic characters are also discussed, with particular emphasis on petal indumentum, staminal connective shape, ovary indumentum, stigma shape, monocarp size and shape, and seed indumentum. Biogeographical relationships in the genus are discussed, and the significance of the Barisan mountain range and the Quaternary volcanic tuffs around Lake Toba are highlighted as potential ecological barriers limiting dispersal.

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.

Optimization of pollen characters on a molecular tree confirms that granular monosulcate pollen, as in Anaxagorea and subfamily Ambavioideae, was ancestral in the family. However, granular structure is derived for angiosperms as a whole, and exine characters are highly homoplastic in Annonaceae. Because columellar taxa (Annickia, Bocageeae) diverged earlier than previously thought, columellae may have re-originated in the common ancestor of Malmeoideae and Annonoideae, which make up most of the family, with several later reversals to granular structure. In Malmeoideae, loss of the sulcus and origin of a verrucate tectum occurred in the tribe Miliuseae, followed by an uncertain number of origins of disulculate pollen. Tetrads arose several times in Annonoideae, but reverted to monads in Isolona and probably Uvarieae. Recognition that microspores rotate during development in Annona and Cymbopetalum suggests that the proximal thin area in these taxa is a modified distal sulcus, but rotation does not occur in all tetrad groups; a broader survey is needed to evaluate this phenomenon.~{\textcopyright} 2012 The Linnean Society of London, Botanical Journal of the Linnean Society, 2012, 169, 190{\textendash}221.}, keywords = {angiosperms, Magnoliales, morphology, palynology, phylogeny, SYSTEMATICS}, isbn = {1095-8339}, url = {http://dx.doi.org/10.1111/j.1095-8339.2012.01241.x}, author = {Doyle, James A. and Le Thomas, Annick} } @article {600, title = {Molecular phylogenetics of Uvaria (Annonaceae): relationships with Balonga, Dasoclema and Australian species of Melodorum}, journal = {Botanical Journal of the Linnean Society}, volume = {163}, number = {1}, year = {2010}, pages = {33-43}, publisher = {Blackwell Publishing Ltd}, abstract = {An extended molecular phylogenetic analysis of Uvaria (Annonaceae) is presented, using maximum parsimony, maximum likelihood and Bayesian methods, based on sequences of four plastid DNA regions (matK, psbA-trnH spacer, rbcL and trnL-F).
