Epiphytic herbs with oblong-elliptic, compressed, monophyllous pseudobulbs 1.5-2.5 cm. long and 1.0-1.5 cm. wide, nearly hidden by the conduplicate im-bricating bases of several conspicuous, foliaceous bracts. Leaves from the apex of the pseudobulbs and the blades of the foliaceous bracts oblong-ligular to ligular, coriaceous, the apices obtuse or obscurely emarginate, 6-14 cm. long and 1.5-2.5 cm. wide. Inflorescences 1-2 lax, slender, deflexed, few-flowered racemes 3-4.5 cm. long. Flowers of moderate size, conspicuously larger than those of Rodriguezia secunda, pale yellow or greenish yellow with, a yellow lip. Sepals dissimilar, the dorsal sepal narrowly oblong, obtuse, concave, about 2.5 cm. long, the laterals connate for their entire length, forming a single conduplicate segment below the lip, about 2.6 cm. long, the apex shortly bifid, the base geniculate in profile. Petals obliquely oblong, obtuse, about 2.5 cm. long. Lip adnate to the foot of the column, about 2.5 cm. long and 1 cm. wide, the free limb obovate-spatulate, the apex deeply emarginate and 2-lobed, the mid-nerve thickened and projecting be-tween the apical lobes as a short apicule, the base produced into a short, curved, subulate spur. Column subcylindric, the apex dilated and subclavate, with pro-jecting arms, the basal half minutely puberulent, the base without a foot.
