TYPE: = Bulbophyllum croceum Lindl. 1830

SYNONYMS *Diphyes sect Corymbosae Blume 1825; SECTION Corymbosa [Bl] Avery. 1994

Characterized by distinct pseudobulbs with 2 to more flowered inflorescence, a very short rachis with the flowers in a subumbellate inflorescence carrying white, yellow, orange or bright red without purple and sepals and petals glabrous to papillose but not ciliate. These orchids have creeping to patent rhizomes giving rise to pseudobulbs carrying a single, persistent leaf that blooms on an elongate to subumbellate, racemose, 2 to many flowered inflorescence carrying resupinate flowers with the pedicel basal node hardly above the attachment of the floral bract. The sepals are free and have 3 to 7 veins, the laterals are the same but 1 to 3 times as long as the dorsal sepal and the petals are 1 to 3 veined. The mobile, undivided lip is on a thin ligament. The column has the stigma proximally usually not protruding. The stelida are shorter to longer than 1/2 the length of the column and the lower margin often has a tooth. The anterior surface of the anther is concave or not, and the anterior margin is drawn out to a beak or not. There are 4 pollina, with or without stipes.

There are about 70 species in this section occuring in montane forests at elevations up to 2000 meters in India, China, Taiwan, eastward to the Philippines, Sulawesi and the Lesser Sunda Islands.

Entries below with an asterix are listed in publications by J J Vermeullen and so are more likely correct than ones without. Species with a question mark in front, seem to me to not conform and so please use with caution. If a sectional name has a "`" in front then it is a complete section with all the known species represented.
