Herbs, epiphytic or lithophytic. Rhizome stout, with many fibrous roots. Pseudobulbs ± clustered, ovoid-cylindric to conic,
rather long, sheathed, apex 2-leaved. Leaves petiolate, relatively large, papery. Inflorescence racemose, proteranthous or hysteranthous,
pendulous; greater part of peduncle covered by sheaths at anthesis; floral bracts persistent, relatively large. Flowers resupinate,
not opening widely, large; pedicel and ovary cylindric, 3-ridged. Sepals similar, fleshy, campanulate (united and saccate at base).
Petals shorter and narrower than sepals, base not saccate; lip oblong, funnel-shaped, 3-lobed near apex, spurless, lateral lobes erect,
embracing column, base saccate and enclosed in basal sac of lateral sepals. Column curved, rather long, winged; anther cap incumbent,
oblong; pollinia 4, in 2 pairs, waxy, oblong-pyriform, depressed, base with flat caudicles, attached to a sticky substance; stigma
concave; rostellum triangular. Capsule with 6 longitudinal ridges, apex with persistent column.
