“…However, recent morphological cladistic analyses ( Doyle and Le Thomas 1994 ;Johnson and Murray 1995 ;Doyle and Le Thomas 1996 ;Chatrou et al 2000 ) as well as molecular phylogenetic studies ( Doyle et al 2000 ;Richardson et al 2004 ;Pirie et al 2006 ;Couvreur et al 2008 ) have elucidated many intergeneric and higherlevel relationships. The grouping of Greenwayodendron with Piptostigma in an early diverging position within the SBC was already inferred in previous molecular phylogenetic analyses ( Richardson et al 2004 ;Pirie et al 2006 ).…”

The coastal lowland rain forests of eastern Africa are well known for their high levels of plant endemism. A new genus of Annonaceae, Mwasumbia, is described from Tanzania, underscoring this high biodiversity and represented by a single species, Mwasumbia alba. The new genus presents several morphological characters suggesting a close relationship to two other African genera, Greenwayodendron and Polyceratocarpus. Maximum parsimony and Bayesian molecular phylogenetic analyses based on two plastid markers, rbcL and the trnL-trnF region, strongly support the close relationship of these three genera to one another as well as to two other African genera, Annickia and Piptostigma. Together these five genera form a moderately supported clade within the so-called short-branch clade of Annonaceae. A detailed morphological and palynological comparison between Mwasumbia and the four other genera shows that this new genus exhibits a combination of features unique within this group: intermediate tertiary leaf venation, exclusively bisexual flowers, slightly imbricate sepals, valvate petals, outer and inner petals equal in length, numerous stamens, four carpels, few and uniseriate ovules, few and sessile monocarps, and verrucate sulculate pollen grains. Phylogenetic analyses also suggest the genus Piptostigma, as currently circumscribed, to be paraphyletic. An IUCN conservation status of VU D2 is proposed, reflecting the narrow distribution of the single species.

“…Moreover, regarding the reticulate nature of character expression in Annonaceae, the taxonomic level at which a phylogenetic analysis is performed determines the character choice. Contrasting with a family-wide phylogenetic analysis, an analysis at the tribal or genus group level requires different data matrices informative only for the particular group examined, as was elegantly shown by Johnson and Murray (1995) in their analysis of the tribe Bocageeae.…”

“…Circumscription of genera within the family was initially founded on characters emphasizing the diversity of floral morphologies represented in the family, which recapitulates many trends found with angiosperm evolution at large (Johnson & Murray 1995, Endress & Doyle 2009, Endress 2011: apocarpy/syncarpy, polypetaly/sympetaly, bisexual/unisexual flowers, reductions in stamen and carpel number, and changes in ovule number.…”

On the basis of molecular phylogenetics, pollen morphology and macromorphology, a new genus of the tribe Miliuseae, Hubera, segregrated from Polyalthia and allied to Miliusa, is established and described. It is characterized by the combination of reticulate tertiary venation of the leaves, axillary inflorescences, a single ovule per ovary and therefore single-seeded monocarps, seeds with a flat to slightly raised raphe, spiniform(-flattened peg) ruminations of the endosperm, and pollen with a finely and densely granular infratectum. Twenty-seven species are accordingly transferred to this new genus.
