Description:
Species Description - Medium-sized, robust, single-stemmed plants of understory, the trunk short, erect, 0.5-5(10) m X 10-17 cm, usually covered by dead leaf sheaths, the lowest part sometimes bare, unarmed, ringed by close, prominent leaf scars. Leaves 8-15, erect, in typical funnel-shaped crown that collects litter; petiole (including sheath), 0.7-1.5 m long, almost terete, dark green, strongly armed with slightly flattened, black spines 1-25 cm long, these clearly disposed in lateral, oblique rows 3-5 cm apart; rachis 3.5-5.2 m long, with spines arranged as on petiole but fewer and smaller; pinnae 70-95 per side, linear-lanceolate, subcoriaceous, plicate, 38-140 X 0.5-7.5 cm, the apical segments much wider (6-20 cm). Inflorescences 1 or 2 per plant, at first obliquely erect, arching at top when fruiting; peduncle terete, yellowish to brownish-green lepidote, 0.6-1.5 m long, the upper part densely armed with black prickles 0.5-3 cm long; prophyll 70 cm long, flattened, abaxially setose, hidden by leaf sheaths; peduncular bract 60-75 cm long, inserted at ±2/3 distance from base of peduncle, the upper part fusiform, coriaceous, dark-brown tomentose, densely armed with black prickles 5-15 mm long; rachis 10-25 cm long, with many rachillae 6-12 cm long. Infructescence a dense, subglobose head. Fruits 2.5-4 X 4-7 cm, turbinate, densely congested, grayish brown, the rounded apical part covered by black, curved spines 5-12 mm long, with rostrum 5-8 mm long; cupule to 2.5 cm high, pale brown, with minute, appressed setae. Fl (Aug-Dec), fr (Mar-Sep); common on well-drained soils on granitic bedrock, forming fairly dense populations on hilltops and slopes, especially on Mont Belvedere, Montagne la Fumee, and the trail to Roche Bateau. Mourou-mourou.
