Rock-dwelling, sometimes forming extensive mats. Stems long, pendulous, wiry, new branches arising below leaves, aerial roots often produced from lower nodes. Leaves 1 per node, 1–12 per flowering stem, 2–9 cm long, 1–2 mm wide (rarely more), cylindric, elongate, usually curved, subtended by a sheathing bract (soon deteriorating, often leaving stringy remains). Inflorescence terminal, 1- or 2-flowered; pedicels (including ovary) 1–2 cm long, thread-like, subtending bract tiny and deciduous; flowers with labellum at top, sepals and petals whitish, cream or yellow with a few red to brown streaks at base, labellum white, devoid of markings, chin-like extension of fused sepal-bases well-developed, c. 5 mm long, cylindric, shallowly cleft. Dorsal sepal recurved, narrowly ovate, 10–15 mm long; free part of lateral sepals divergent, tapered to blunt or pointed apex, c. 10–15 mm long. Petals divergent, narrow-obovate or lanceolate, c. 10–15 mm long, narrower than sepals. Labellum curved, c. 15 mm long when straightened; lateral lobes erect, short, blunt; mid-lobe ovate, with upcurved, deeply wavy margins; lamina callus consisting of 3 parallel ridges, becoming wavy as they extend onto mid-lobe.
