Common Name The Petal-Less Genyorchis

Flower Size 1/8"

Found in Nigeria, Ivory Coast, Sierra Leone, Ghana, Cameroon, Gabon, Gulf of Guinea Islands, Congo, Zaire and Uganda in rainforests, mangroves and lowland forests at elevations of sealevel to 1400 meters as a small sized, hot to cool growing epiphyte with ovoid or oblong, 4 angled pseudobulbs arising from a woody rhizome and carrying 2, spreading, oblong-elliptic, apically bilobed, fleshy or leathery leaves that blooms on a 2" [5 cm] long, basal, several flowered, racemose inflorescence.

This species was known as Genyorchis pumila, it and Bulbophyllum pumilum are confused by many authorities and B pumilum is said to be a syn of Genyorchis pumila but Bulbophyllum pumillum has two leaves and is white flowered while the latter is single leafed and most often green, red or white flowered. Since Schlechter made his accepted genus Genyorchis and made Genyorchis pumila as the type, he erroneously assumed that Dendrobium pumilum was the basionym but that name was invalid and so Genyorchis apetala was created and is now the type species of the genus Genyorchis with Bulbophyllum apetala Lindley as the basionym.

CAUTION This is a confusing genus and the species have not been well sorted in common literature. I do not have the proper references to be sure of any of the determinations for this genus so please use with caution!
