Biosystematics
During a recent survey of Atlantic central African orchids, we collected four orchid specimens in Rio Muni (Equatorial Guinea) that share the general morphology of Angraecum gabonense, the most frequent member of Angraecum section Pectinaria in Central Africa, but differ in leaf shape and flower size. Further inspection of specimens deposited at the Wageningen herbarium and cultivated in their greenhouse led to the discovery of additional specimens from the Monts Doudou area in Gabon. Comparison with other Angraecum specimens indicate that these collections represent a new species, which we describe here as Angraecum atlanticum, the fifth species of Angraecum section Pectinaria recorded in central Africa. The new species is restricted to submontane forests covering the mountain chain situated along the coasts of Gabon and Equatorial Guinea. The distinguishing features of the species include its leaves, which are more widely spaced than A. gabonese, and are 2.2 mm wide; its petals and sepals, which are slightly longer than the lip; its spur, which is somewhat inflated in the middle; and its larger ovary. Information on the ecology, phenology and distribution of Angraecum atlanticum is presented, along with a preliminary conservation assessment using the IUCN Red List Categories and Criteria.
