Clustering robust palm climbing to 30-45 m. Stems without sheaths 30-50 mm in<br />

diameter, with 45-60 mm; internodes 35-50 cm long, although more commonly 18-25<br />

cm. Leaf sheath moderately to pr<strong>of</strong>usely armed with black-tipped finely triangular,<br />

upward pointing or spreading spines; sheaths on upper portion <strong>of</strong> stem more sparsely<br />

armed; juvenile sheaths particularly pr<strong>of</strong>usely armed; dense brown-black indumentum<br />

present on mature sheaths, more sparse on juvenile sheaths; ocrea 20-30 cm long, dry,<br />

gradually tapering at the apex, reflexed, tattering longitudinally and disintegrating,<br />

dark tan mid-brown without, crimson-brown within, armed as the sheath although<br />

spines <strong>of</strong>ten concentrated at the apex, particularly on juvenile sheaths. Leaves up to<br />

3.5m long; petiole 5-12 cm long, 1.5-2.5 cm. wide, mid to dark green with scattered<br />

brown-black indumentum, particularly on upper surface, abaxially rounded, adaxially<br />

lightly to moderately concave proximally becoming flattened in cross section distally,<br />

armed along the margins with inequidistant black-tipped angular spines up to 1.4 cm<br />

long, spreading in many directions; rachis 1.5-2 m long, shaped as the petiole,<br />

becoming more trapezoid in cross section then triangular in cross-section distally,<br />

armed as the petiole proximally, spines becoming more sparse distally, with sparse<br />

brown indumentum present below; cirrus up to 1.5-2 m. long, triangular in cross<br />

section, only very sparsely armed with reflexed bulbous-based black-tipped spines,<br />

sparse brown indumentum below; leaflets always composed <strong>of</strong> a single-fold, 45-65 on<br />

each side <strong>of</strong> the rachis, equidistant, opposite to sub-opposite proximally, inequidistant,<br />

alternate distally, papyraceous, conspicuously pendulous, finely linear-lanceolate,<br />

base abruptly contracted, apex broadly to finely acuminate, <strong>of</strong>ten breaking <strong>of</strong>f, 30-45<br />

cm long (commonly up to 60 cm) 1.2-2.8 cm broad at the widest point, ± concolorous,<br />

glaucous blue-green, margins armed with inequidistant exceptionally fine, 5-8mmlong,<br />

forward facing curved or angular black-tipped spines; 1 costulate midrib armed<br />

as the margins although spines much longer.; acanthophylls 4.5-5 cm long.<br />

Inflorescences, numbering 6-12 produced simultaneously in the distal 1.5-2.2m<br />
