Stout epiphytic herbs with ovoid or subcylindric, often laterally compressed or furrowed pseudobulbs, the apex with 1-4 broadly plicate leaves, the plants considerably resembling a robust Stanhopea. Inflorescences elongate, pendulous or erect racemes from the base of the pseudobulbs. Flowers usually many, fleshy, relatively large and conspicuous. Sepals subequal, broadly concave, the dorsal sepal free, the laterals usually connate at the base. Petals subequal to the sepals but usually smaller. Lip 3-lobed, fleshy, concave, with a concave or subsaccate, basal claw or hypochile, lateral lobes large, erect, triangular or subreniform, the apical lobe carinate, concave or spreading; disk fleshy, with variously shaped appendages. Column erect, usually pubescent, somewhat arcuate, subclavate or narrowly winged, without a foot. Anther terminal, operculate, incumbent, 1-celled or imperfectly 2-celled; pollinia 2, waxy.
