Small, caespitose epiphyte; thickened pseudobulbs lacking; stems short, slender, bearing a single leaf. Blades oblanceolate, mostly rounded or emarginate at apex, attenuate at base, 3.5-10 cm long, 0.6-1.5 cm wide, glabrous, coriaceous (prominently striate longitudinally when dried). Inflorescences densely flowered, terminal racemes 10-22 cm long; flowers pale violet-purple, persisting in fruit, minute (to 2.7 mm long); sepals +/- ovate, acute or obtuse, to 1.3 mm long, papillate to minutely glandular; petals minute, much smaller than sepals, broader than long, held to either side of the minute trilobate lip. Fruits obliquely 3-sided, +/- ellipsoid, 4-6 mm long, green. Croat 14938. Apparently uncommon, though because of its habit in trees it is often overlooked. Flowers in the late dry season (April) and the early rainy season (May). The fruits develop by June.
