Description Erect, caespitose, epiphytic herbs with approximate, oblong-ovoid to elliptic- oblong, compressed pseudobulbs 2-5 cm. long and 1-2.5 cm. wide, the truncate apices usually monophyllous, the lower portions of the pseudobulbs enveloped in the conduplicate bases of the several distichously imbricating bracts the uppermost 2 or 3 of which are conspicuously foliaceous. Leaves ligular, obtuse or shortly and unequally 2-lobed at the apex, coriaceous, 5.5-14 cm. long and 1-2.8 cm. wide, contracted below into very short, conduplicate petioles. Inflorescences 1 or 2 erect or arching, few- to about 12-flowered racemes or weakly branching panicles, equaling or somewhat exceeding the leaves, up to about 25 cm. in length. Flowers relatively large for the genus, averaging about 1.5-2 cm. in diameter, greenish white to greenish yellow with purple or reddish brown markings. Sepals free, subequal, spreading, the dorsal sepal elliptic-lanceolate, acute, somewhat concave, the reverse surface with a distinct keel, 9-12 mm. long and 3.5-5 mm. wide, the lateral sepals spreading or somewhat reflexed, ligular to oblong-lanceolate, obtuse to subacute, 8-12 mm. long and 2.5-5 mm. wide, the reverse surfaces with a distinct central keel. Petals subequal to the dorsal sepal, lanceolate, acute, 9-12 mm. long and 2.5-3.5 mm. wide. Lip entire, spreading or slightly convex, the blade obovate-oblong, truncate, up to about 12 mm. long and 7 mm. wide, the narrower base conspicuously thickened and adnate to the base of the column, the broader apex shallowly emarginate, the reverse surface with a distinct central keel, the disk with a short, subquadrate, basal boss terminating at the apex in 2 distinct, parallel, erect, fleshy, puberulent calli. Column up to about 3 mm. long, semiterete, the undersurface below the stigma with 2 distinct, ligular, porrect arms.
