Two new Malagasy species of Bulbophyllum and one of Cynorkis are described, each known from a single collection made in 2001. Nervilia simplex (Thouars) Schltr. and N. crociformis (Zoll. & Morren) Seidenf. are shown to represent the same taxon from the Mascarene Islands. New synonymies are established for taxa of Bulbophyllum, Aerangis, Angraecum, and Oeceoclades from Madagascar and the Mascarenes.
