Ecology and distribution
Trop. Afr.
Biology : Tree 3-20 m high, solitary or clumped; crown narrowly pyramidal or columnar in the open to more ovoid underneath other trees, with a terminal tuft of large leaves on the stem, and lateral branches ending in tufts of smaller leaves. Stem 10-25 cm in diameter; stilt-roots to 3 m high. Leaves 0.3-1.1 m long, 1.5-3 cm wide, on young vigorous trees 0.5-1.5 m long and 2.5-5 cm wide, rigid,; prickles on leaf margin 0.6-3.3 mm long. ? head at anthesis 4.3-6 cm long, 2-4.5 cm across, erect, the ovaries all separate; styles reniform. Syncarp solitary, ovoid with pointed apex, (6-)11-15 cm long, 6-10 cm wide, with 450?600 drupes. Peduncle 16-31 cm long; bracts to 36(-57) × 3 cm; drupes 18-34 × 5-12 × 5-18 mm, (4-)5-6-angled, 1(-3)-locular; pileus 2.5-5 mm long, 5-18 mm across, slightly raised; stigma 1(-3), reniform to horseshoe-shaped; endocarp 7-11 mm long, mesocarp fibrous. Staminate flowers in densely branched spiciform inflorescences; peduncle ± 12 cm long; axis of inflorescence 10-30 cm long with 6-10 branches, each subtended by conspicuous large off-white or cream bracts to 31(-89) × 5 cm; inflorescence branches cylindrical, 3-17 × 1-3 cm, densely packed with many flattened stemonophores 2-7.5(-11) mm long, each bearing at its apex (2-)4-7(-11) stamens; filaments (0.6-)1.1-3.7 mm long, slightly flattened; anthers 1-2.8 mm long, ellipsoid, apex rounded with a small apiculum, creamy white.
Ecology : Along river-banks, in freshwater swamps, often gregarious; 0-1200 m.
  Gomes e Sousa (1966) says that the species is fast diminishing in numbers, as river-banks are being cleared.
