Abstract

ABSTRACT We recognize 30 species of the pantropical genus Xylopia L. from Madagascar and an additional three species from the Mascarene Islands. Of the six sections of the genus, three are represented in the region: sect. Xylopia, sect. Verdcourtia, and sect. Stenoxylopia. All species are endemic, and many are microendemics of conservation concern. The greatest species richness occurs in humid forests below 1000 m. Taxonomic review supports the hypothesis that the genus dispersed to Madagascar from continental Africa five times. Ten new species are described: Xylopia anomala D.M.Johnson & N.A.Murray, sp. nov., X. australis D.M.Johnson & N.A.Murray, sp. nov., X. carinata D.M.Johnson & N.A.Murray, sp. nov., X. galokothamna D.M.Johnson & N.A.Murray, sp. nov., X. lokobensis D.M.Johnson & N.A.Murray, sp. nov., X. longirostra D.M.Johnson & N.A.Murray, sp. nov., X. marojejyana D.M.Johnson & N.A.Murray, sp. nov., X. ravelonarivoi D.M.Johnson & N.A.Murray, sp. nov., X. retusa D.M.Johnson & N.A.Murray, sp. nov., and X. sclerophylla D.M.Johnson & N.A.Murray, sp. nov. An identification key, technical descriptions, illustrations, and distribution maps are provided.

标题木香属植物(番荔枝科):马达加斯加和马斯卡林群岛的种

摘要/ ABSTRACT摘要:我们鉴定了30种来自马达加斯加的泛热带属Xylopia L.和另外3种来自马斯卡林群岛。在该属的6个科中，有3个科在该地区有分布:木皮科、草皮科和木皮科。所有的物种都是地方性的，许多是保护关注的微型地方性物种。最大的物种丰富度发生在1000米以下的潮湿森林。分类审查支持该属从非洲大陆分散到马达加斯加五次的假设。描述了10个新种:异常木藻d.m.j onson&n.a.m urry，十一月，x.x carinata d.m.j onson&n.a.m urry，十一月，x.x galokothamna d.m.j onson&n.a.m urry，十一月，x.x marojejyana d.m.j onson&n.a.m urry，十一月，x.x ravelonarivoi d.m.j onson&n.a.m urry，十一月，x.x retusa d.m.j onson&n.a.m urry，十一月，和x.x硬藻d.m.j onson&n.a.m urry，十一月。提供了识别密钥、技术描述、插图和分布图。
