Plants to 40 cm tall stem cylindrical (4 mm in diameter), densely leafy. Leaves linear-lingulate (8- 10 cm x 9-12 mm), thin but coriaceous. Inflorescences generally half the length of the leaves; peduncle short (12-15 mm), nearly entirely covered by the 3-4 sheaths, the longest of which is 5 mm long; bracts tubular, obtuse, 10 mm long; flowers average (16 mm long), white. Sepals lanceolate-lingulate, wider toward the base, slightly attenuate toward the obtuse apex and 6 veined, the median slightly larger (16 x 4 mm) than the laterals (14 x 3.5mm). Petals (14 x 4.5 mm medially), slightly attenuate toward the base, subacute apically and 8 veined. Labellum (16 x 8.5 mm medially) bent-concave with a fine median costa, slightly above the base, then enlarged in an obovate-attenuate lamina near the center, or greatly enlarged nearly to the rounded apex: 11 veined; spur pendent, thin, cylindrical and generally 12 mm long. Column very short, slightly thicker than tall (2 x 2.5 mm); auricles 1.5 mm tall, superior angle projecting and acute, the inferior obtuse; median tongue very short, narrow and acute.
