Bulbophyllum Section Calamaria Schltr.
Description:
Schlechter (1924) first used the name Calamaria for a group of orchids that occur in Madagascar, the Comoros, the Mascarenes, and Africa. Section Calamaria is characterized by ovoid to orbicular, sometimes flattened, unifoliate or bifoliate pseudobulbs. The inflorescence is a many-flowered raceme with a rachis as thick as the peduncle or swollen, with the flowers inserted into dimples. The floral bracts cover the whole flower or at least the pedicel and ovary of the flowers, which are arranged in rows or spirally. The sepals are glabrous or verrucate, rarely fine hairy, with always entire margins. The lateral sepals are free. The lip is thick, recurved in the middle, with glabrous to long hairy margins. The stelidia are linear, falcate or recurved, and acute to acuminate. The anther has a protrusion that is often as long or longer than the stelidia. All species are adapted to drought through succulent vegetative parts.
