Small, epiphytic herbs 3.5-12 cm. tall, the equitant leaves distichously arranged in the form of a broad fan. Leaf blades articulated to the conduplicate, imbricating, persistent bases, coriaceous, lanceolate to gladiate as seen in profile, obliquely acute, 2-9 cm. long and 0.4-1.2 cm. wide. Inflorescences 1-10 slender, many-flowered, axillary racemes about equaling the leaves in length, the rachis densely hispid with spreading glandular hairs. Flowers small, greenish or yellowish, on short hispid pedicels subtended by ovate, acute, membranaceous, ciliate bracts. Sepals suborbicular, concave, about 2 mm. in diameter, the reverse surfaces somewhat hispid, with a central elevated keel, terminating in a short mucro. Petals subequal to the sepals, very shortly clawed at the base, the blades orbicular, concave, about 2 mm. in diameter, the reverse surfaces more or less hispid, with a ciliate central keel, terminating in a short mucro. Lip entire, linear-navicular, acute, strongly incurving, about 4-5 mm. long when spread out, the base with a fleshy, papillose, subquadrate to suborbicular, cushion-like callus, produced at the sides into 2 short, divergent, horn-like appendages each about 1 mm. in length.
