Pseudobulbs glabrous, 1-leaved, relatively close together, parallel to rhizome or at a small angle, cylindric-ovoid, 7-20 by 1.5-3 mm, narrowed at base, ribbed. Leaves patent, coriaceous, glabrous but margins irregular papillate-erose, linear, linear-spathulate, or narrowly elliptic, 12-45 by 2-6 mm, acute or obtuse, midrib grooved above, crested below. Inflorescences 1-flowered, solitary. Peduncle glabrous, 3-7 mm long, at base with tubular bracts, 4.5-15 by 2.5-3 mm, acute, crested, in higher parts with 3 bracts, lowest suborbicular, 4 by 3 mm, acute. Bracteoles tubular, 5.5 by 2.5 mm, obliquely truncate, acute, crested. Pedicels glabrous, 3-3.5 mm long. Ovary glabrous, ovoid or sigmoid-claviform, 5.5-6.5 by 2-2.5 mm, 6grooved. Median sepal glabrous, elliptic-obovate, 6.5-9 by 3-5 mm, acute. Lateral sepals glabrous, obliquely ovate, 7-10 by 5-6.5 mm, connate, in basal part forming a rounded mentum, subulate-acuminate at tip, 3nerved. Lateral petals glabrous or finely papillate along apical half of margin, obliquely oblong-elliptic, 6-7 by 2.2-2.5 mm, obtusish or acute, 1-nerved. Lip densely barbate on underside only, linguiform, 6-6.5 by 2-2.5 mm, slightly curved, fleshy, basal margins membranous and curved upwards, obtusely acuminate at tip, crested above, retuse at base. Column short, conoid, 2 by 1 mm, apical margin 3-tipped. Anther papillate along apical part, otherwise glabrous, cucullate with upcurved lateral margins, 1.2 by 1.3 by 0.7 mm, rounded, base retuse. Column-foot compressed-cylindric, 3-4 mm long, straight but curved forward at tip, widened and 2-lobed at tip. Capsule not seen. (After van Royen, 1979)
