Small, caespitose, epiphytic herbs 10-25 cm. tall, with short, inconspicuous, approximate, subcylindric, monophyllous pseudobulbs 1-2.5 cm. long and 0.2-0.5 cm. wide, the bases enveloped in several brown, papery, imbricating sheaths. Leaves fleshy, linear-lanceolate to semiterete, acuminate, 9-22 cm. long and 0.3-1.0 cm. wide, contracted at the base and apparently continuous with the apices of the slender pseudobulbs. Inflorescences pendulous, unbranched racemes 2.5-6 cm. long, produced from the bases of the foliaceous stems. Flowers small for the genus, usually 3-8, on slender pedicels, each subtended by a broad, acute to acuminate, spathaceous, papery bract. Sepals subequal, free, spreading, pure white to pale yellow, linear-lanceolate, acuminate, 20-23 mm. long and 3-4 mm. wide. Petals subequal to the sepals, spreading, linear-lanceolate, acuminate, pure white to pale yellow, 18-20 mm. long and 2.5-3 mm. wide. Lip entire to obscurely 3-lobed, concave, obovate to elliptic-oblong, abruptly acute, or obtuse and apiculate, the margins minutely denticulate to conspicuously lacerate, white, usually irreg-ularly spotted rose-purple, 15-20 mm. long and 12-18 mm. wide, the base adnate to the base of the column, the lateral margins erect at the very base and somewhat incurving over the column, the limb spreading, the disk with a short, fleshy, bifid or bicarinate callus. Column semiterete, 7-9 mm. long, the margins of the apex projecting, forming an entire, denticulate to fimbriate hood over the anther, the sides of the clinandrium below the hood with a pair of short to elongate, denticulate processes.
