Abstract
Summary Six new species: Bulbophyllum caniceps, B. cochinealloides, B. fierenanaense, B. geminiflorum, B. oenanthum and B. rudolphus are described for the first time. The identity and nomenclature of Bulbophyllum cylindrocarpum is discussed and its var. andringitrense is recognised at species rank as B. jeanbosseri . Bulbophyllum aubrevillei and B. kieneri are compared with the latter becoming a synonym. The history and identities of Bulbophyllum pentastichum vs B. quadrifarium are clarified and the necessary taxonomic changes and type selections are made. A new sect. Inversiflora is formally described.
