General Description
Rhizome creeping, prostrate and rooting, sometimes branched, 1/2 -1 1/2 cm thick. LEAVES: Petiole 10-45 cm long, shortly sheathed, a little shorter than or up to 2.5 x as long as the leaf-blade, glabrous or minutely puberulous. Geniculum 1-2 cm long.Leaf-blade hastate, long auriculate, cordate with a very wide sinus or obtuse at the base, glabrous above, midrib and lateral nerves minutely puberulous below, apex acute or acuminate, middle lobe ovate to oblong-elliptic, 9-29 cm long, 4-14 cm broad, almost twice to more than 3 times as long as broad, widest below the middle. Lateral lobes obtuse, ovate-elliptic, up to 18 cm long, 7 cm wide, sometimes almost or totally absent. Numerous prominent lateral nerves, with 2-5 less prominent lateral nerves between them, with very numerous, transverse, slender veinlets between them. Lateral nerves near the edge anastomosing in 2-3 marginal nerves. INFLORESCENCE:Peduncle slender, 0.4-1.1 x as long as the petiole, 7-27 cm long, glabrous or puberulous. Spathe lanceolate-elliptic, when flowering spreading backwards, after flowering closing again, 2-3.5 cm long, acute-mucronulate, white, green or olive-brown. Spadix slender cylindrical, 2.5-3.5 cm long, 1.2-1.4 x as long as the spathe, short stiped or subsessile. male part more or less densely flowered, female part less densely flowered. male part ± 1.5 x as long as the female part. Pistils depressed-globose, with some whitish spots, and a very short contracted style. Stigma discoid. Stamens 4-6. Thecae oblong or elliptic. male flowers with thecae covering the side of the synandrium entirely and also the larger part of the top of the synandrium. The thecae disappear after flowering and the remnants of the synandrium are then close together. INFRUCTESCENCE: Berries depressed-globose. Dried seeds 1.6-2.4 mm long, 0.9-1.5 mm broad; 1.5-2.0 x as long as broad, light brown with many whitish spots.
Phenology
Flowering and fruiting throughout the year.
Habitat
On wet places in mud or in the water, at the banks of rivers and brooks, mostly on shady places in forests.
Diagnostic
Thecae covering the synandrium completely on the sides and (sometimes only partly) on the top. When flowering spathe open down to the base and the spadix exserted. This species is long overlooked. Nevertheless the male flowers are very typical. Consequently, the species stands relatively isolated within the genus.
Distribution
Gabon, Congo, Zaire.
