Stout epiphytic herbs with ovoid, somewhat angular pseudobulbs 7-10 cm. long and 4-6 cm. wide, the apex with 2-3 lanceolate, acute, plicate leaves 25-45 cm. long. Inflorescences elongate, pendent racemes from the base of the pseudobulbs. Flowers about 5 to numerous, fleshy, relatively large and conspicuous, not fully expanding, variable in color from pale yellow to reddish brown, with red or brownish purple spots. Sepals fleshy, concave, the dorsal sepal free, more or less erect, oblanceolate, shortly acute, 3.5-4 cm. long and 2-2.2 cm. wide, laterals connate at the base, obliquely elliptic-lanceolate, acute, 3.5-4 cm. long and 2-2.5 cm. wide. Petals membranaceous, oblanceolate-obtuse or very shortly and broadly acute, 3-3.5 cm. long and 1.8-2 cm. wide. Lip very fleshy, gibbous, 3-lobed, the basal claw or hypochile rectangular-linear, concave, the lateral lobes erect, broadly triangular, the apical lobe of the lip elongate, carinate, 1.8-2 cm. long and about 1.8-2 cm. wide when spread out, obovate, obtuse; disk with a very conspicuous, erect, oblong-quadrate, fleshy callus with 2 identical, divergent, forked processes arising from a common restricted base, the one pointing toward the apex and the other toward the base of the lip. Column stout, pubescent, 1.8-2 cm. long and 1.3-1.5 cm. wide, subterete below, narrowly winged above, the wings confluent at the apex, forming a hood over the clinandrium.
