Usually terrestrial, sometimes epiphytic, creeping; stems elongate; internodes 1-6 cm long; cataphylls thin, 2-9 cm long, weathering into fine longitudinal fibers, ultimately deciduous. LEAVES with petioles erect, 18-36(40) cm long, weakly sulcate; blades 3-parted, moderately thin, leaflets sessile or on petiolules to 2 cm long; median leaflet ± elliptic to ovate, 12-25 cm long, 4-11 cm wide, long-acuminate at apex, obtuse at base, lateral leaflets inequilateral ca. two-thirds as long as median leaflet, short-acuminate at apex, inner margin attenuate at base, outer margin rounded; the midrib in the median leaflet sunken above, raised below; primary lateral veins 3-5 per side, sunken above, raised below; departing midrib at 35°-45° angle, the collective vein arising from the base, 3-5 mm from margin. INFLORESCENCE erect, shorter than leaves; peduncle 9-22 cm long, terete; spathe lanceolate or ovate, green becoming white or yellow, 4-6 cm long, 1.2-2.5 cm wide, acuminate at apex, rounded at base; spadix green to yellow, scarcely tapered, 3.7-5 cm long, 4-6 mm diam. at base: the flowers 4-lobed, ca. 1.7 mm in both directions, the sides sigmoid; ca. 6 flowers visible in the principal spiral, ca. 5 flowers visible in the alternate spiral: lateral tepals 0.9-1 mm wide, the inner margin convex; pistils emergent; stigma elliptic; stamens emerging irregularly throughout spadix, held at edge of tepals; thecae ellipsoid. INFRUCTESCENCE with spadix to 6.5 cm long, berries violet-purple, globose to ovoid, with a short beak.
