Sepals and petals united and forming a perianth tube, only apical portions free; perianth tube sometimes dilated and saccate at base, sometimes with a deep sinus between lateral sepals, outer surface often verrucose; petals much smaller than sepals; lip enclosed within perianth tube, adnate to apex of column foot, usually small, usually clawed at base, simple or 3-lobed; disk with a pair of globose calli at base. Column elongate, with a short but distinct column foot at base, winged toward apex, sometimes with a pair of toothlike projections at apex; anther borne on a filament, large, subterminal, incumbent; pollinia 2, granular-farinaceous, usually composed of friable massulae, without caudicles; stigma raised, shield-shaped.
