Here we describe a new species of the pan-tropical plant family Annonaceae named Uvariopsis lovettiana. It closely resembles another Eastern Arc endemic species, U. bisexualis, and its possible relationships with this species are discussed. A description with illustrations is presented as well as a suggestion for the IUCN conservation status of this new taxon.10aAnnonaceae10aENDEMISM10aIUCN CONSERVATION STATUS10aMONOECY10ataxonomy10aUDZUNGWA MOUNTAINS10aUSAMBARA MOUNTAINS1 aCouvreur, T L P1 aLuke, W R Q uhttp://www.ingentaconnect.com/content/nhn/blumea/2010/00000055/00000001/art00008http://dx.doi.org/10.3767/000651910X49919601450nas a2200193 4500008004100000245007200041210006900113300001400182490000600196520084100202100001501043700001401058700001701072700001801089700001501107700001401122700001901136856010101155 2010 eng d00aAn ethnobotanical investigation of the Annonaceae on Mount Cameroon0 aethnobotanical investigation of the Annonaceae on Mount Cameroon a2148-21580 v43 aAn ethnobotanical survey was carried out in the Mount Cameroon area, Southwest region of Cameroonto determine the uses of the different species of the Annonaceae. Ethnobotanical information wascollected through the show-and-tell/semi-structured method and personal interviews during field trips.Eight villages were surveyed in the study: Njonji, Bakingili, Bomana, Mapanja, Likombe, Bwassa,Liwenni and Bimbia. 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. These results show that there is need for protection of theAnnonaceae in the region to ensure sustainability.1 aFocho, D A1 aEgbe, E A1 aChuyong, G B1 aFongod, A G N1 aFonge, B A1 aNdam, W T1 aYoussoufa, B M uhttp://www.academicjournals.org/JMPR/abstracts/abstracts/abstracts2010/18Oct/Focho%20et%20al.htm01822nas a2200241 4500008004100000020001400041245015400055210006900209260002900278300001000307490000800317520102200325653001901347653002401366653001701390653001601407653001601423100001701439700002001456700002201476700002701498856005501525 2010 eng d a1095-833900aMolecular phylogenetics of Uvaria (Annonaceae): relationships with Balonga, Dasoclema and Australian species of Melodorum0 aMolecular phylogenetics of iUvaria iAnnonaceae relationships wit bBlackwell Publishing Ltd a33-430 v1633 aAn 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). 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. © 2010 The Linnean Society of London, Botanical Journal of the Linnean Society, 2010, 163, 33–43.10aclassification10amolecular phylogeny10anomenclature10aplastid DNA10aSYSTEMATICS1 aZhou, Linlin1 aSu, Yvonne, C F1 aChalermglin, Piya1 aSaunders, Richard, M K uhttp://dx.doi.org/10.1111/j.1095-8339.2010.01045.x02297nas a2200193 4500008004100000020001400041245016800055210006900223260002200292300000900314490000600323520161400329653003301943100001801976700002201994700002002016700001902036856004802055 2010 eng d a1935-975600aChloroplast DNA polymorphism and phylogeography of a Central African tree species widespread in mature rainforests: Greenwayodendron suaveolens (Annonaceae)0 aChloroplast DNA polymorphism and phylogeography of a Central Afr bSpringer New York a4-130 v33 aGeographic patterns of genetic variation at chloroplast markers have been successfully used to address the phylogeography and the demographic history of many plant species. 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.10aBiomedical and Life Sciences1 aDauby, Gilles1 aDuminil, Jérôme1 aHeuertz, Myriam1 aHardy, Olivier uhttp://dx.doi.org/10.1007/s12042-010-9041-6
