Species Description - Epiphytes with terete to slightly compressed, erect stems to 1 m. Leaves 4 or 5, broadly lanceolate, plicate, stiff, to 16 X 5 cm. Inflorescences terminal, without pedunculate continuation of stem, subtended by slightly reduced leaf. Flowers large, showy, rose-purple with yellow center of lip; sepals lanceolate, acute, 7 X 2-2.4 cm; petals lanceolate, acute, crenulate in apical half, 6.5 X 2.5 cm; lip unlobed, obovate, emarginate, crenulate in apical half, with paired, basal, keellike projections and linear ridges to near apex, 7 X 5.5 cm; column clavate, 4.5 cm long.
