    General Description
    Plants 4.6(1.0-10.0) m tall; stems 1.3(0.9-1.9) cm diameter, clustered. Leaf petioles 3.4(1.0-6.0) cm long; rachises 47.9(17.0-77.0) cm long, 5.7(4.2-7.5) mm wide, the spines usually <1 cm long, mostly abaxial, recurved with markedly swollen bases; pinnae 9(7-13) per side of rachis, without long, filiform apices, without a beard of spines at the bases, without spinules or dense tomentum at the bases adaxially; basal pinna 14.0(5.5-24.0) cm long, 2.3(1.4-3.0) cm wide; cirri well-developed, with acanthophylls, with few spines abaxially, mostly on proximal part only, with no intermediate acanthophylls present, usually with a wide gap between pinnae and acanthophylls (i.e., gap wider than that between adjacent acanthophylls). Inflorescences with the rachis angular, slightly twisted, thicker than the few, closely spaced and spirally arranged rachillae, each rachilla not or rarely adnate to the rachis, subtended by an acute bracteole and with a well-developed axillary pulvinus; peduncles 2.4(1.0-5.4) mm wide; peduncular bracts 26.3(20.5-33.0) cm long, broad, the surfaces ribbed or ridged, brown tomentose or glabrous, sparsely to moderately covered with short, straight or sinuous, briefly swollen-based, diagonally or vertically oriented spines, these flattened or triangular in crosssection, whitish-brown proximally, black or brown distally, with tomentose margins; rachillae 11(10-16), glabrous or scarcely tomentose initially; proximal rachillae 6.0(3.5-10.5) cm long, 0.9(0.6-1.2) mm wide; stamens 6; fruits 12.3(10.9-13.9) mm long, 8.0(7.0-9.4) mm wide, the surfaces uneven with numerous, subepidermal, short, often branching (Y-shaped) fibers; fruiting corollas less than one quarter as long as fruits, splitting irregularly into 3 lobes, the lobes often splitting again; endocarps narrowly ellipsoid with rounded apices, the pores lateral.
