Leaf cirrate, c. 4.3 m long including cirrus and petiole; sheath dark green, with sparse to abundant, caducous indumentum of minute, irregular, brown and white scales, spines numerous, 2 - 25 x 0.5 - 5 mm, black, planar, triangular, stiff, slightly deflexed, scattered evenly throughout sheath, spine bases slightly swollen adaxially, sheath mouth densely armed; knee 60 - 90 mm long, 18 - 21 mm wide, moderately to densely armed, spines and indumentum as on sheath; ocrea 14 - 23 mm, forming a hard, woody, persistent flange, divergent from stem, armed with bristle-like spines and spines as on sheath, base of ocrea extending along petiole to an acute angle; flagellum absent; petiole 20-30 mm, 14-17 mm wide and 7-8 mm thick at base, flat adaxially, rounded abaxially, indumentum as on sheath, with numerous short triangular spines; rachis up to 3 m, with few, very small, triangular spines, with irregularly-arranged grapnel spines abaxially; leaflets 13 - 15 each side of rachis, irregularly arranged in divergent pairs and solitarily, broadly lanceolate, cucullate, longest leaflets near middle of leaf, 28 - 40 x 6.5 - 9 cm, apical leaflets 19 - 35 x 1.8 - 3 cm, distal leaflets widely spaced, basal leaflets small and apparently reflexing, with few bristles 1 - 2.5 mm towards base of adaxial surface of mid-rib and rarely on other major veins, unarmed abaxially, leaflet margins unarmed or with very few bristles 1 - 1.5 mm, increasing in density towards leaflet apex, transverse veinlets moderately inconspicuous; cirrus 1.2 - 2 m, cirrus grapnel spines arranged irregularly. Staminate inflorescence up to 3.8 m long including c. 35 cm sterile tip, branched to 3 orders; prophyll 12 - 16.5 x 1 - 1.3 cm, strictly tubular, with 2 keels, prophyll mouth entire, with narrow, acute, triangular limb to one side, indumentum as on sheath, densely armed with spines 1 - 18 mm long, similar to spines on sheath; peduncular bracts absent (always?), rachis bracts 19 - 26.5 x 0.7 - 1.5 cm, similar to prophyll, densely armed towards apex as prophyll; primary branches up to c. 12, to 28 cm long, 31 - 38 cm apart, strongly recurving, with up to c. 250 rachillae, bracts on primary and secondary branches funnel-shaped; rachillae 4 - 20 x c. 1 mm, sublinear, glabrous; rachilla bracts c. 0.5 x 1.2 mm, subdistichous, glabrous; floral bracteole c. 0.8 x 1 mm. Staminate flowers 3.3 - 4.1 x 1.8-2 mm in bud near anthesis, very sweetly scented; calyx 1.8 - 2 mm diam., tubular in basal 1 mm, with 3 lobes 0.7 - 1 x 1 - 1.2 mm, glabrous; corolla 3 - 3.6 x 1.8-2 mm in bud, scarcely united at base, glabrous; stamens 6, filaments 1.5 - 1.8 x 0.3 mm, anthers 1.6 - 2.1 x 0.4 mm; pistillode inconspicuous. Pistillate inflorescence similar to staminate inflorescence, but branched to 2 orders; primary branches c. 25 cm long, strongly recurving, with c. 26 rachillae, bracts on primary branch funnel-shaped; rachillae 25 - 70 x 2 mm, sublinear or irregular; rachilla bracts c. 1.2 x 1.7 mm, subdistichous, glabrous; proximal floral bracteole obscured by distal bracteole, distal floral bracteole 1.3 -1.5 x 1.5 mm, glabrous, scar from sterile staminate flower c. 0.2 mm diam. Pistillate flowers c. 3-3.5 x 2 mm at anthesis, very sweetly scented; calyx c. 2 mm diam., tubular in basal c. 2 - 2.2 mm, with 3 lobes to c. 0.9 x 1 mm, glabrous; corolla c. 2.4 x 1.5 mm, tubular in basal c. 1.3 - 2 mm, with 3 lobes to c. 1.1 - 1.2 x 1 mm, glabrous; staminodes 6, staminodal ring c. 1 mm high; gynoecium 1.8 - 2 x 1.1 - 1.4 mm, ovoid, stigmas 0.6 - 0.8 mm long. Sterile staminate flowers not seen. Fruit globose, c. 8 x 6 mm including beak 1.5 mm (available material unripe), with c. 20 longitudinal rows of shallowly channelled scales with entire, but uneven margins.
