It closely resembles another Eastern Arc endemic species, U. bisexualis, and its possible relationships with this species are discussed.

Results indicated that 28 (68.3\%) of the 41 species of Annonaceae present in thearea are widely used by local people. Some 28 diseases are cured using 20 species. The barks andleaves of these species are the most commonly used plant parts. Seven other species provide woodused in the construction of houses and huts.

The additional taxa include the monotypic West African genus Balonga, the monotypic South-East Asian genus Dasoclema and seven Australian representatives of the genus Melodorum. The results indicate that all of these taxa are nested within a well-supported clade otherwise consisting of Uvaria species, indicating that their taxonomic treatment needs to be reassessed. The distinguishing morphological characteristics of the taxa are re-evaluated and interpreted as specialized adaptations of the basic Uvaria structure. The genus Uvaria is accordingly extended following the transfer of these species, necessitating six new nomenclatural combinations and two replacement names.~{\textcopyright} 2010 The Linnean Society of London, Botanical Journal of the Linnean Society, 2010, 163, 33{\textendash}43.}, keywords = {classification, molecular phylogeny, nomenclature, plastid DNA, SYSTEMATICS}, isbn = {1095-8339}, url = {http://dx.doi.org/10.1111/j.1095-8339.2010.01045.x}, author = {Zhou, Linlin and Su, Yvonne C.

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.}, keywords = {Biomedical and Life Sciences}, isbn = {1935-9756}, url = {http://dx.doi.org/10.1007/s12042-010-9041-6}, author = {Dauby, Gilles and Duminil, J{\'e}r{\^o}me and Heuertz, Myriam and Hardy, Olivier} }
