Two new species of angraecoid orchid from East and South-central Africa are described and illustrated. Rhipidoglossum lucieae is known from the Eastern Arc Mountains of Tanzania (West Usambaras) and has been misidentified as R. pulchellum in previous floristic treatments. Rhipidoglossum philatelicum is reported from the Eastern Highlands of Zimbabwe (Bvumba and Chimanimani Mts) and has been misclassified under R. subsimplex. Distribution maps and the conservation status of these two novelties are provided. Future directions in epiphytic orchid species discovery in eastern tropical Africa are proposed.

坦桑尼亚和津巴布韦的两个新物种Rhipidoglossum（兰科：Angraecinae）

描述和说明了来自非洲东部和中南部的两种新的类黑线兰花。Rhipidoglossum lucieae以坦桑尼亚的东弧山（西乌桑巴拉斯）而闻名，在以前的植物学研究中被误认为是R. pulchellum。据报道，从非洲东部的津巴布韦高地（Bvumba和Chimanimani Mts）报道了集邮的Rhipidoglossum philatelicum，并且在R. subsimplex下被错误分类。提供了这两个新奇的分布图和保护状态。提出了在非洲东部热带地区发现附生兰花物种的未来方向。
