Herbs, perennial, terrestrial [lithophytic or epiphytic]. Roots slender, fibrous; pseudobulbs green, conic, ovoid, or ellipsoid, slightly compressed, soft (2 pseudobulbs typically present, parent pseudobulb enveloped in old leafbases, connected laterally by short rhizome to daughter pseudobulb, which gives rise to current-year’s stem, parent pseudobulb often retaining dried stem of previous year). Stems somewhat angled, slender, glabrous; cauline bracts 2 (–3), enclosing base of stem. Leaves 2 or 3–7, basal, sheathing pseudobulb and proximal part of stem, conduplicate or plicate, glabrous. Inflorescences terminal, 3–40-flowered racemes, lax; peduncle and rachis glabrous; floral bracts subulate to triangular-lanceolate. Flowers resupinate, maroon-purple, yellowish green, or green, pedicellate; dorsal sepal oblongelliptic, linear-oblong, oblong-lanceolate, or lanceolate, margins revolute, apex obtuse to acute; lateral sepals oblong-lanceolate, lanceolate, ovate-oblong, or elliptic, falcate or not, margins revolute or involute, apex obtuse to acute; petals filiform, linear, linear-oblanceolate, or narrowly spatulate, tubular or strongly revolute; lip strongly arcuate-recurved, obcordate, oblong-flabellate, or suborbiculate, base broadly cuneate, slightly auriculate, apex emarginate or subtruncate, mucronate or not, apical margins erose-serrulate to crenulate-wavy; column arcuate, slender to stout, weakly to strongly winged at apex; anther apical, anther cap yellow or green; pollinia 2 pairs, yellow, waxy. Fruits capsules, erect, ellipsoid to ovoid, obscurely to prominently winged, glabrous.
