Abstract

While revising the genus Angraecum (Orchidaceae) for the Mascarenes, a new taxon endemic to Mauritius was identified and it is here described as Angraecum baiderae. More than 300 Angraecum specimens, including types, collected in the Mascarenes and Madagascar, and available at DBEV, G, K, KM, L, MARS, MAU, MO, P, REU, SEY, TEF, and TAN were studied to confirm the taxonomic status of this new taxon. Its conservation status was assessed as Endangered. Furthermore, this paper presents detailed descriptions, conservation status, and a key to all species of Angraecum sect. Perrierangraecum occurring in the Mascarenes.
