Summary Descriptions and illustrations are presented for three new species to science, Vepris udzungwa Cheek , V. lukei Cheek (both Udzungwa Mts, Tanzania), and V. robertsoniae Q.Luke & Cheek (SE Kenyan kaya forests), in the context of a synoptic taxonomic revision and with an identification key to all the known unifoliolate taxa of Vepris in continental Africa. The new species are described and illustrated, while the remaining 10 taxa are given skeletal taxonomic treatments (lacking descriptions). One widespread species in montane eastern Africa is renamed as V. simplex Cheek because its previous name, V. simplicifolia (Engl.) Mziray, is predated by V. simplicifolia Endl. (basionym of Sarcomelicope simplicifolia (Endl.) T.G.Hartley, a widespread species of Australia, Lord Howe and Norfolk Islands, and of New Caledonia). The new combination Vepris hanangensis var. unifoliolata (Kokwaro) Cheek is made. Full or provisional conservation assessments are presented for all species using the IUCN 2012 standard. Of the 13 taxa, nine are considered threatened or near threatened, of which one is Near Threatened, three are Vulnerable, two Endangered, and three Critically Endangered, with two of the latter, both of the Uluguru Mts of Tanzania, possibly extinct globally, although not yet assessed on the IUCN Red List.

摘要介绍了三个新发现的科学物种:Vepris udzungwa Cheek、V. lukei Cheek(均为坦桑尼亚udzungwa Mts)和V. robertsoniae Q.Luke &;在对非洲大陆所有已知的Vepris单叶分类群进行分类修订和鉴定的背景下，对肯尼亚东南部kaya森林的Cheek进行了研究。对新种进行了描述和图解，其余10个分类群进行了骨骼分类处理(缺乏描述)。非洲东部山区的一种广泛分布的物种被重新命名为单纯性葡萄球菌，因为它以前的名字是单纯性葡萄球菌。Mziray，是由v.s simplicifolia Endl。(单纯性肌群基底)t.g.哈特利，广泛分布于澳大利亚、豪勋爵岛和诺福克岛以及新喀里多尼亚)。本文研制了一种新组合“单叶鹿角”。根据国际自然保护联盟2012年的标准，对所有物种进行全面或临时的保护评估。在13个分类群中，9个被认为是受威胁或近危，其中1个是近危，3个是易危，2个是濒危，3个是极度濒危，后者中的2个，坦桑尼亚的Uluguru山，可能在全球范围内灭绝，尽管尚未在IUCN红色名录上进行评估。
