Trop. Afr.
Biology : Stems 20-30 m long, up to 4 cm in diameter; leaves ecirrate, 1-1.75 m long; flagellum emerging from the leaf axil, up to 3.5 m long; leaflets often grouped and generally irregularly arranged; male and female inflorescences similar in aspect, up to 3,5 m long; fruits oblong to broadly ellipsoid, 1,5 cm long, 1 cm wide, covered by 17-20 rows of scales, dull brown when ripe.
Ecology : This species largely prefers to grow in swamps, where it can form very dense populations, and riverine forests. It can be also found in the understory of wet forests. Species exclusively present in lowlands although in East Africa also reported to grow at 1000-1500 m (Dransfield, 1986).
