Basionym: Phreatia micrantha
Epiphytic, erect, 13-17 cm high. Rhizome very short; roots filiform, flexuose, thin, glabrous. Pseudobulbs depressed-subglobose, very small, about 0.5 cm diam., 1-leaved, covered with 2-3 leaf-bearing sheaths. Leaves suberect or erect, narrowly ligulate, subacute, gradually somewhat narrowed towards the base, 10-16 cm long, in the the middle almost 0.7-1 cm wide. Inflorescence ascending or suberect, 2-3 times shorter than the leaves; peduncle slender, 3-3.5 cm long, with a few clasping, acuminate peduncle-scales; rachis densely many-flowered, to 3.5 cm long, 0.7 cm diam. across the flowers. Flowers in very small, glabrous. Sepals ovate, obtuse, about 0.15 cm long; lateral sepals strongly oblique, at the base margins along the front margin conspicuously dilated; semi-oblong, obtuse. Petals obliquely oblong-ovate, strongly obtuse, a little shorter than the sepals; lip at the base very shortly and broadly cuneate, above square-ovate, obtuse, margins slightly undulate, in basal half papillose-puberulous, as long as the sepals, spur porrect, obliquely oblongoid-sacciformi, slightly more than half as long as the blade. Column short; rostellum large, erect, deeply bifid, surpassing the clinandrium; stigma reniform. Ovary very shortly pedicellate, clavate, glabrous, about 0.15 cm long. (After Schlechter, 1919)
