Epiphytic herbs of variable size, up to about 25 cm. tall, with oblong, compressed, monophyllous pseudobulbs up to about 2.5 cm. long and 1.2 cm. wide, usually partially enveloped in the conduplicate bases of the foliaceous bracts. Leaves and bract blades oblong-lanceolate to ligular, obtuse to subacute, coriaceous, up to about 20 cm. long and 2-5 cm. wide, contracted below into short conduplicate petioles. Inflorescences 1 or 2, usually elongate, slender, pendulous, many-flowered racemes up to about 35 cm. long, produced from the base of the current pseudobulb. Flowers of moderate size for the genus, on filiform pedicels subtended by inconspicuous linear-lanceolate, acuminate bracts. Sepals pale green, concave, the dorsal sepal lanceolate, acuminate, 8-10 mm. long and about 2-2.5 mm. wide, the apex slightly recurved, the lateral sepals connate for more than half their length, forming a single bifid segment below the lip, about 10 mm. long and 2.5 mm. wide, the subfalcate, acuminate apices divergently spreading and retrorse in natural position. Petals about 8 mm. long and 1.5 mm. wide, rather obliquely lanceolate, shortly acuminate, white with 2 minute orange spots in the center. Lip with an elongate, slender basal claw, the blade abruptly dilated and trulliform, acuminate, white, about 6 mm. long (with the claw) and up to about 2 mm. wide at the base, the disk with a short, carinate callus.
