摘要

摘要/ Abstract摘要:本文报道了二新种。其中，来自肯尼亚和坦桑尼亚的Phalaena H.Huber节的Ceropegia pseudolugardiae Bruyns一直被认为属于C. lugardiae N.E.Br。但有纤维根，而不是一簇肿胀的，纺锤状的根，典型的藤。这一重要特征在很大程度上被忽视了，因为根茎在大多数植物标本室标本中是不存在的。伪石竹与C. distincta N.E.Br亲缘关系密切。和C. zambesiaca Masinde & Meve，它们都有纤维根，花的细节不同。第二种为安哥拉Laguncula H.Huber组的lubangoensis Bruyns。这是区别于所有其他在本节相当长的花冠裂片。

Two New Species of Ceropegia (Apocynaceae) from Tropical Africa

Abstract: We describe two new species of Ceropegia. Of these, Ceropegia pseudolugardiae Bruyns of sect. Phalaena H.Huber from Kenya and Tanzania has long been considered to belong to C. lugardiae N.E.Br. but has fibrous roots rather than the cluster of swollen, fusiform roots typical of C. lugardiae. This important feature has been much neglected, as the rootstock is absent from most herbarium specimens. Ceropegia pseudolugardiae is closely related to C. distincta N.E.Br. and C. zambesiaca Masinde & Meve, which all share the fibrous roots and differ in details of their flowers. The second species is C. lubangoensis Bruyns of sect. Laguncula H.Huber from Angola. This is distinguished from all others in this section by the considerably longer corolla-lobes.
