Epiphytic or lithophytic herb forming small dense compact clumps. Rhizome creeping, appressed to host, much branched, thin. Pseudobulbs moderately crowded, conical to ovate, somewhat flattened, 7-10 mm x 6-10 mm, pale green, deeply grooved. Leaf solitary on pseudobulb, erect, apical, sessile; lamina narrowly oblong, 5-10 cm x 0.5-0.8 cm, dark green, thin textured, but stiff.
