Aerangis × primulina (Rolfe) H.Perrier, in Fl. Madag., Orchid.(2): 116 (1941).
Angraecum × primulinum Rolfe, Gard. Chron., III, 7: 388 (1890).
Known only from a single inflorescence removed from a cultivated plant in 1890 and preserved in the Herbarium at Kew. It was described as a probable natural hybrid between Aerangis citrata and Aerangis hyaloides. Inflorescence similar to Aerangis citrata but the flowers smaller and closer together. Flowers pale yellow with a white lip; dorsal sepal not arching forward as in Aerangis citrata; lip intermediate between the putative parents in shape; spur greenish, parallel to the pedicel, 15-20 mm long.
As given for the genus.
