Repent, epiphytic herbs with elongate, slender, often branching stems enveloped in tubular, papery sheaths which often weather away, the caespitose 2-ranked foliaceous growths usually freely rooting from the base, distant or terminal on the stems. Leaves 3-5, coriaceous, 3-10 cm. long and 1-2 cm. wide, elliptic-lanceolate, acute, the conduplicate bases closely imbricating, forming a complanate, sheathing petiole. Inflorescences usually several slender, 1-flowered scapes 1.5-2 cm. long, produced from the axils of the leaves. Flowers small. Sepals subequal, green with reddish brown margins, lanceolate, acute, 7-10 mm. long and 2.5-3.5 mm. wide, the dorsal sepal concave and incurving over the column, the laterals adnate to the foot of the column, widely spreading or reflexed. Petals subequal to and parallel with the dorsal sepal, green with reddish brown margins, linear-lanceolate, acute, 6.5-7.5 mm. long and 2-3 mm. wide. Lip conspicuously 3-lobed, 6-8 mm. long and 3.5-4.5 mm. wide, the basal half canaliculate and adnate to the foot of the column, the lateral lobes erect and parallel with the column, the area between the truncate apices with a short, obtuse, concave, fleshy callus; the mid-lobe broadly spreading, subquadrate, strongly reflexed, the truncate apex deeply emarginate, the center orange-yellow with pale yellow, undulate margins, the under-surface with a short, fleshy, apiculate keel. Column stout, semi-terete, about 5 mm. long, produced at the base into a short, stout foot.
