Description: Epiphytic or epilithic herbs, sympodial; roots creeping over the surface of the substrate, fibrous. Stems differentiated into rhizome and pseudobulb; pseudobulb of several internodes.
Leaves scattered along the pseudobulb or tufted at its apex, 1 to several per shoot, distichous, conduplicate, sessile.
Inflorescence racemose, several–many-flowered, terminal; flowers resupinate [or not]. Dorsal sepal free, similar to lateral sepals. Lateral sepals free. Lateral petals free, about as long as, or slightly shorter than dorsal sepal. Labellum free, attached at base of column; lamina unlobed, bearing 1 or 2 calli or longitudinal keels.
