    General Description
    Perennial herb with tubers, with several months dormancy during the dry period; tuber globose, flattened, brown, 4-6 cm diameter and ca. 3 cm thick. LEAVES 1 (-2). 1-2 inflorescences appearing with or without the leaves; cataphylls reaching 20 cm long; petiole green, 15-45 cm long, reaching 2 cm diameter; sheath 3-9 cm long, leaf blade broadly ovate, chordate at the base, cuspidate at the apex, green, (13-) 18-40 x (10-) 14-37 cm, tapering to a point of length 0.5-2 cm long; 4-7 primary lateral veins on each side, 2-3 inferior veins inserted at the base at the midrib and often shortly briefly joined; inner collective veins strongest, 0.5-2 cm from edge of the leaf blade; outer collective veins ± weak and 1-2 mm from edge of leaf blade; sometimes with a middle collective vein, 5mm from edge of leaf. INFLORESCENCE: Peduncle 8-18 cm long, reaching 4 mm diameter, green or slightly reddish. Spathe somewhat decurrent on the peduncle, elliptic, not constricted, tapered to a point, more or less cuspidate, 9.5-12 x 4-6 cm yellowish-green to purple inside and outside, entirely open during anthesis, closing again during fructation, the upper part desiccates, only the lower part is persistent. Spadix 7-9 cm long, reaching 1 cm diameter; male zone 5-7 cm long; fertile as far as the tip, where it ends in a small conical sterile tip; female zone ca. 1.5 cm and 12-20 flowers, of which some flowers are bisexual near to the male flowers. Presence, sometimes, of the synandriums with the aborted stigmas, near the female flowers. Male flowers with 2-4 stamens (4-6 Perrier de la Bathie 7218) joined into a synandrium ca. 2 mm at top, stretched, a little angular, flattened and rough towards the top, ca. 4 x 2 mm, the sides a little curved. 4-8 (-12) thecae fixed at the top on the outside edge, with . Present their openings directed towards the base; thecae globose and broadly elliptic, ca. 1.2 mm diameter, yellow, dehiscing from one large slit. Female flowers ca. 3 x 3 mm; pistil surrounded by a synandrodium ca. 2 mm long, urceolate; stigma and style exserted; synandrodium, with edges at the top ± bulging, rough, bareing, in the case of the bisexual flowers, some thecae, more usually 1-2(-4), some times incompletely developed; style short; ovary ovoid, progressively attenuating towards the short style; ovule subglobose, funicle very short; stigma discoid, concave at the top, ca. 1 mm diameter, whitish.
