(Fig. 671.1) Epiphytic, semi-pendent herbs. Stem up to 25 cm long, usually shorter, rigid, becoming pendent with the weight of the leaves. Leaves 3–10, oblong, unequally emarginate, flat, coriaceous. Inflorescence 5–25 cm long, racemose, pendent, many-flowered, flowers radiating in all directions; rachis c. 1 mm in diameter; floral bracts 1 mm long, deltoid. Flowers 4–7 mm in diameter, lasting longer than two days, pale green spotted crimson, fragrant. Sepals and petals subsimilar, narrowly oblong to narrowly spatulate, lateral sepals adnate, at least in part, to base to column foot. Labellum hinged to apex of column foot, bilobed, spurred, side lobes erect, broad at base, tapered to a decurved tip at apex, midlobe vestigial, or possibly modified to form the distal part of disc; disc broad, thick, with an erect, digitiform callus at distal side of spur entrance; spur slightly projecting forward, 1 mm long, broad, internally evenly tapered from a wide orifice to a blunt point at the apex, walls thick, externally much broader laterally than anterior-posterior-aligned, apex often notched. Column 1.0–1.5 mm long, sharply incurved from about the middle, column foot in line with proximal half of column proper; anther cap shallow, with an elongate, narrow, slightly decurved beak, pollinia four, in two closely appressed, subequal pairs, each pollinium attached by an elastic caudicle to a long, narrow stipe; stigma deeply set, subrhombic to almost circular, rostellum decurved, bifid.
