"Erect or ascending, epiphytic or terrestrial herbs; the stems up to about 15 dm. long, simple, branching or producing new plants at the nodes, lepidote [rough, scaly] or furfurescent [?]. Leaves 5-20 cm. long and 2-6.5 cm. broad, elliptic to broadly elliptic-lanceolate [tapering to a pointed apex], acuminate, glabrous [smooth] or slightly furfurescent at the base dorsally; leaf-sheaths densely pubescent [covered with fine, soft hairs], lepidote or furfurescent, older sheaths appearing pustulate [blistered or pimpled]. Flowers purple to white. Sepals 4.5-6 cm. long and about 1.2-1.6 cm. broad, ligulate [strap-shaped] to lanceolate, acute, the laterals somewhat oblique. Petals a little shorter than the sepals and up to about 2 cm. broad, obtuse or acute. Lip 4-6 cm. long and 3-4 cm. broad, obovate [egg-shaped, narrower at base] or oblong-obovate, obtuse [rounded at apex], glabrous, apex undulate, with 2 small calluses [ibid.] at base.
