    Habitat
    Found on nurtient rich and deep soil of the savannah and open woodlands as well as on shallow stony soils (not infrequent on Inselbergs). Loves humidity, therefore frequently in stream and river valleys and gallery forests or humid depressions in savannahs. Also frequent on cultivations (‘Kulturland’) and intensely cultivated land such as cocoa plantations
    Distribution
    West Africa, restricted to the West African part of the Guinean-Congolese region and the Guinean-Congolese-Sudanese transition zone, with a distribution gap between Ghana and Sierra Leone
    Diagnostic
    Style barely visible or absent, Ovary bilocular.
    Phenology
    Flowering from March till May and fruiting from October till November.
    General Description
    Tuber flattened globose to globose, 3-15 cm in diameter, the roots arise exclusively from the upper half. LEAF emerge a few days after the inflorescence, 30-120 cm high. Petiole 22-100 cm long, dark green with purple spots. Blade 18-70 cm in diameter; rachis slightly cuneiformly winged (‘leicht keilförmig geflügelt’) from 2nd division order leaflets onwards. Terminal leaflets inversely egg-shaped to elongate egg-shaped, 6-14 x 2-5 cm, shortly attenuate, green blue-green; margin smooth, slightly undulate, rarely toothed. Cataphylls not known. INFLORESCENCE appearing before the leaf, can grow over 1 m tall. Peduncle 25-70(-80) cm long, 0.5-2 cm in diameter, dirty green to purple with whitish brown spots. Spathe 7-20 cm long, arranged into a narrow cylindrical to ovoid (‘oval’) tube and an elongate, triangular, open limb by a slight constriction; constriction not always obvious. Tube 4-8 x 3-5 cm, cylindrical to ovoid (‘oval’); outside green to light-green; inside basally smooth or with few, short, circular papillae and very scattered, tongue like, short emergences, greenish purple, with veins somewhat raised. Open limb erect, 5-12 x 3-7 cm, long attenuate, outside green to pale green, inside greenish white. Spadix subsessile or stipitate for 0.3-1 cm, 13-40 cm long, usually twice as long as the spathe. Pistillate zone ± cylindrical, 0.8-2.5 x 0.4-1 cm, flowers relatively congested, but do not always touch each other, at least 3 flower whorls. Staminate zone obconic, 1-2 x 0.4-1.5 cm, flowers congested. Appendix 11-35 cm long, long conic to slighly club-shaped, acutely attenuate, yellow, yellow-green to greenish, basal quarter buldging (‘bauchig’), basally not or hardly constricted, surface slightly rugulose. Staminodes absent; sterile zone between pistillate and staminate zone absent; ratio of pistillate to staminate zone 0.6-0.7 : 1. Pistillate flowers 3-4 mm long; ovary rotund-ovoid, 2.2-3.5 x 2.3-3 mm, bilocular, cream coloured; stigma sessile, 0.5-1.5 x 1-2 mm, circular from above, arched in lateral view, with 2 rounded-acute humps. Staminate flowers 1-1.5 mm; anthers free, 1 x 1 mm long, elongate-(länglich-)cubical, two forming one flower; filaments free, very short or not visible; thecae semi-circular, one pore visible per theca; pores apical, circular-broadly elliptic (‘oval’); connective slightly channelled. Pollen orange, inaperturate, 45 x 46 cm, striate to psilate. INFRUCTESCENCE appearing with the leaf, peduncle clearly elongating after flowering; infructescence stalk 20-35 cm long; infructescence slightly conical, 8-10 x 3-5 cm. Berries globose, 1 x 1 cm, orange red orange. Smell unknown.
