Epiphytic herbs with slender, monopodial, often rather flexuose foliaceous stems, 4 to about 18 cm. tall. Leaves 2-ranked on the stems, narrowly linear-lanceolate, acute and apiculate or acuminate, subcoriaceous, often glaucous, usually in alternating groups of unequal length, the blades articulated to the sheathing bases and ultimately deciduous below, 1-4 cm. long and 0.2-0.45 cm. wide. Peduncles filiform, 1-flowered, produced from the axils of the leaves. Flowers small, translucent, white spotted with pink or purple. Sepals free, the dorsal sepal oblong-lanceolate, acute, slightly concave, about 5 mm. long and 2 mm. wide, the lateral sepals obliquely oblong-lanceolate, acute, slightly concave, about 6 mm. long and about 2.5 mm. wide at the base. Petals shorter and broader than the sepals, rather obliquely elliptic-oblong, shortly acute, about 4.5 mm. long and 3.5 mm. wide. Lip sagittate to obovate-spatulate in outline when spread out, the ligular claw slightly arcuate in profile, abruptly contracted at the base and continuous with the short column foot, the blade abruptly dilated and 3-lobed, the short, acute lateral lobes retrorse in natural position, the mid-lobe broadly triangular, shortly acute with a short central keel on the lower surface at the apex, the entire lip, including the claw, about 7 mm. long and 6 mm. wide. Column wingless, stout, about 3 mm. long, the apex truncate, the under-surface with a short, infra-stigmatic ligule, the base produced into a very short foot. Anther and pollinia typical of the genus.
