Erect, epiphytic herbs with slender, branching stems provided with small, very distant, suborbicular, monophyllous, compressed pseudobulbs 6-15 mm. long and 6-15 mm. wide, the bases covered by 2-3 conspicuous, foliaceous bracts, the long internodes very closely enveloped in complanate, imbricating, acuminate, papery sheaths. Leaves subcoriaceous, lanceolate to elliptic-lanceolate, acute, 3.5-15 cm. long and 1-2 cm. wide, contracted below into slender, conduplicate petioles. Inflorescences several very short, 1-flowered scapes 5-10 mm. long, apparently produced simultaneously from the bract axils of the flush of new growth. Flowers very small, often enveloped in 2 glumaceous bracts. Sepals subequal, free, not spreading, concave, oblong-lanceolate, acute to subacute, about 4 mm. long and 2 mm. wide, the laterals adnate to the base of the column, forming a rounded, conspicuous mentum. Petals subequal to the dorsal sepal, ligular, obtuse, about 3 mm, long and 1.5 mm. wide. Lip fleshy, 3-lobed, about 3 mm. long, articulated with the base of the column, the lateral lobes rounded, erect, on either side of a basal concavity which has a short, ligular, fleshy callus, the mid-lobe ovate, subacute, nearly 1/2 the total length of the lip, the basal constriction below the lateral lobes with a transverse, semicircular thickening. Column short, stout, the lateral margins thickened toward the obscurely produced base.
