New combinations in Aerangis are made for six species previously ascribed to Microterangis, for twelve species and one variety in Chamaeangis that are transferred to Diaphananthe, and for Rangaeris rhipsalisocia that is transferred to Podangis rhipsalisocia. The morphological and DNA-based evidence for these transfers is discussed. Aerangis hariotiana (Kraenzl.) P.J.Cribb & Carlsward, Phytotaxa 71: 44 (2012). (Ligação)
