Flowers green to ochre-orange, non-resupinate, scabrid on outer surface. Sepals and petals subsimilar; lateral sepals fused at their oblique bases to enclose base of spur. Lip obscurely 3-lobed, concave, ecallose, spurred at the base. Column short, fleshy; rostellum narrow, bifid, dilated and scutelliform at apex; pollinia 2, subglobose; stipes solitary, linear; viscidium small, reniform.
