Erect stem usually absent (except peduncle), when present rather short, to 8 (-15) cm long. Rhizomes creeping, to 1.2 cm thick. Stipules glabrous, caducous, narrowly ovate to ovate, to 7 mm long, 3.5 mm wide, apex acuminate, margins entire. Leaves succulent, arising from rhizomes or sometimes borne on short erect stems, nearly glabrous, abaxially reddish purple on veins, oblique, ovate, 9-16 (-18) cm long, 5-6 (-10) cm wide, base obtuse, margins entire or nearly so, apex acuminate; venation palmate, veins 7-9; petiole glabrous, to 16 cm long, 7 mm thick. Bracts in pairs, papery, glabrous, caducous, narrowly ovate to ovate, to 8 mm long, 4.5 mm wide, margin entire, apex acuminate. Inflorescence to 25 cm long, usually arising directly from rhizome, rarely from aerial stem, to 8 (-15) cm long, with 1 or 2 cauline leaves, peduncle erect, to 17 cm long, 7 mm across at base. Tepals pale pinkish. Staminate flowers: tepals 4, rarely 6, outer 2 broadly rotund to orbicular, to 15-19 mm long, 15-18 mm wide, inner 2 (4) oblanceolate to narrowly obovate, 10-17 mm long, 6-9 mm wide, stamens 68-84, yellow, clavate, anthers narrowly obovoid, 0.9-1.5 mm long, 0.5-0.8 mm across; filaments free, 1.1-1.7 mm long.
