Pseudobulbs cormlike and ovate, or narrowly cylindric, 1–4-noded, sometimes connected to previousyear’s growth by a persistent slender rhizome. Leaf solitary, arising from apex of pseudobulb, broadly ovate to ovate-elliptic, sometimeswith purple spots above and purple below, base abruptly contracted into a long petiole-like stalk. Inflorescence laxly racemose,arising from apex or laterally from near base of pseudobulb, erect, slender, usually enclosed at base by a few sheathing bracts; rachislaxly many flowered; floral bracts very small. Flowers resupinate, small; pedicel and ovary cylindric-fusiform, slender.
