Abstract

ABSTRACT The genus Vepris Comm. ex A.Juss. (Rutaceae) includes around 85 species occurring mostly in Africa and Madagascar, among which three West and Central African species, differing from others in the area by their simple or unifoliolate leaves, are the object of the present paper. Glycosmis? africana Hook.f., described from the island of São Tomé, is transferred to the genus Vepris, as V. africana (Hook.f.) O.Lachenaud & Onana, comb. nov. This species, which also occurs in Gabon, Angola and the Republic of Congo, was previously known under the illegitimate name V. gossweileri (I.Verd.) Mziray [non V. gossweileri I.Verd.]. It is here illustrated for the first time, and a complete description is presented; it is notable for having androdioecious flowers, rather than dioecious as usual in the genus. Another new combination, Vepris laurifolia (Hutch. & Dalziel) O.Lachenaud, comb. nov. – based on Garcinia laurifolia Hutch. & Dalziel – is published for a West African species, so far known under the younger synonym V. felicis Breteler. This species is newly recorded from Sierra Leone, and an updated description is presented. These two species are compared to the similar V. welwitschii (Hiern) Exell, which is endemic to Angola and still relatively little-known. The conservation status of all three species is assessed, respectively as Near-threatened (V. africana, comb. nov.), Vulnerable (V. laurifolia (Hutch. & Dalziel) O.Lachenaud, comb. nov.) and Endangered (V. welwitschii).

西非和中非种的Vepris com . ex A.Juss。(芸香科)具单叶或单叶，包括两个新的组合

【摘要】紫穗草属(Vepris);(芸香科)包括大约85种，主要分布在非洲和马达加斯加，其中西非和中非的3种，因其单叶或单叶而与该地区的其他物种不同，是本文的研究对象。Glycosmis吗?africana Hook.f。产于s o tom岛，被归入Vepris属，称为V. africana (Hook.f.)。O.Lachenaud & Onana，梳子。11 .这个物种也分布在加蓬、安哥拉和刚果共和国，以前以不合法的名字V. gossweileri (I.Verd.)闻名。[au:] [au:]这是第一次说明，并提出了一个完整的描述;值得注意的是，它有雄蕊异株的花，而不是雄蕊异株的花。另一种新组合，月桂花(Hutch)。O.Lachenaud，梳子。十一月-基于Garcinia laurifolia Hutch。& Dalziel -是一种西非物种，迄今为止已知的较年轻的同义词是V. felicis Breteler。本种新记录自塞拉利昂，并提出了更新的描述。这两个物种与相似的V. welwitschii (Hiern) Exell进行比较，后者是安哥拉特有的，仍然相对鲜为人知。对这三个物种的保护状况进行了评估，分别为近危(V. africana, comb.)。11月)，易受伤害(V. laurifolia)(哈奇。O.Lachenaud，梳子。十一月)和濒危(V. welwitschii)。
