Stems 96 x 0.49-0.53 cm, simple, cane-like, laterally compressed, ancipitose, erect to arching, straight. Leaves 12, articulate, alternate, sub-coriaceous and similar in length; sheaths 3.30-3.34 x 0.49-0.53 cm tubular, laterally compressed, minutely striated; blades 11.5-14.3 x 1.3-1.65 cm, linear-lanceolate, acuminate, sub-erect, margin entire, spreading. Spathes 1-2, 6.0-7.8 x 0.68 cm, tubular, conduplicate, acute, papyraceous. Inflorescence ca. 17 cm long, apical, racemose, arched, sub-densely many-flowered; peduncle 8 cm long, laterally compressed, straight, nearly totally hidden by spathe; apically provided with a bract 0.24-3.04 mm long, linear-oblong, acuminate, embracing. Floral bracts 4-16 mm long, prominent, about as long as ovary or longer, linear-triangular, acuminate, embracing. Ovary 7-10 mm long, terete, thin, not inflated, unornamented. Flowers ca. 36, opening in succession from base to apex, eventually all open, resupinate, lip always facing rachis, medium green, concolor; fragrance not registered.
