Leaf petioles 20.5(15.0-30.0) cm long; rachises 157.5(125.0-190.0) cm long, 12.2(10.1-14.2) mm wide, the spines usually >1 cm long, mostly adaxial or lateral, straight with briefly swollen bases; pinnae 10 per side of rachis, without long, filiform apices, with an adaxial beard of spines at the bases, without spinules or dense tomentum at the bases adaxially; basal pinna 39.2(32.0-46.5) cm long, 6.5(5.7-7.3) cm wide; cirri well-developed, with acanthophylls, without spines abaxially, with intermediate acanthophylls present, without a wide gap between pinnae and acanthophylls. Inflorescences with the rachis ridged, not twisted, much thicker than the numerous, closely spaced and spirally or irregularly arranged rachillae, each rachilla not or only briefly adnate to the rachis, subtended by an acute bracteole and with a well-developed axillary pulvinus; peduncles 8.5(6.5-11.7) mm wide; peduncular bracts length no data, broad, the surfaces ribbed, brown tomentose, densely covered with long, straight or sinuous, briefly swollen-based, diagonally or vertically oriented spines, these flattened or triangular in cross-section, whitish-brown proximally, black or brown distally, with tomentose margins; rachillae number no data, glabrous or scarcely tomentose initially; proximal rachillae 16.0 cm long, 1.7 mm wide; stamens number no data; fruits 36.2(21.5-42.6) mm long, 16.6(12.7-18.3) mm wide, the surfaces smooth, without any apparent subepidermal fibers; fruiting corollas to half as long as fruits, splitting irregularly into 3 lobes, the lobes often splitting again; endocarps ovoid to obovoid with prominent, peaked apices, the pores lateral. Canopy reaching liana. Stem solitary, to 30 m long and 5 cm in diameter, usually covered with persistent leaf sheaths. Leaves 2-3 m long, the axis with slender, black spines, distally often unarmed; pinnae 9-10 on each side, evenly spaced, elliptic, 25-45 cm long and 6-12 cm wide; distal part of the rachis with 8-9 pairs of pinnae transformed into climbing hooks.
