Description:
Species Description - "Stemless" plants of understory, the stem subterranean, in shape of saxophone. Leaves 10-15, erect, forming funnelshaped crown that collects litter; petiole (including sheath) 1.1- 1.5 m long, green, almost terete, canaliculate above, armed with black, flattened spines, the spines basally winged, 2-10 cm long, ± clustered; rachis 3-4.7 m long, abaxially armed with spines similar to but smaller than those of petiole; pinnae 75-100 per side, straight, linear-lanceolate, 22-110 X 1-4 cm, the apical segments not wider. Inflorescences 1 (rarely 2) per plant; peduncle straight, terete in transverse section, green, 0.6- 1.5 m long, the upper part densely armed with black spines 2— 5 cm long; prophyll ±60 cm long, densely brown setose outside; peduncular bract 70-130 cm long, inserted at Vi—2h distance from base of peduncle, fusiform, densely brown-velvety setose, with few black spines at tip; rachis 20-70 cm long, armed with black spines to 1.5 cm long, bearing many rachillae 12-15 cm long. Fruits brown, oblong-ellipsoid, with rostrum to 1 cm long, smooth to spinulose on upper part but early glabrescent, 3-4 X 1.5-2 cm, dehiscing and exposing bright yellow mesocarp and black endocarp; cupule with black setae.
Distribution and Ecology - Fl (Jul-Dec), fr (Jan-Jun); very common in forest understory, mostly on well-drained clayey soils, often found in very high density, especially on Plateau la Douane and along Clique Limonade Trail. Counana.
