LEAVES spirally arranged, marcescent, 13-17 living ones in the crown, erect, plus 5-15 dead ones; sheath litter-accumulating, c. 28 x 24 cm, abaxially yellow-brown to red-brown with dense red-brown tomentum, adaxially yellow-brown; auricles and petiole absent, though an apparent petiole of up to 30 cm may be present; proximal part of leaf litter-accumulating; rachis 2.8-4.5 m long, proximally 3-4.6 x 1-3 cm diam. and channelled with a central ridge, in mid-leaf c. 1.5 cm wide and keeled, with scattered scales abaxially; leaflets 6-15 on each side of the rachis, the proximal large and multi-fold, 165-250 x 13-24 cm and attached to the rachis for up to 1.5 m, the more distal ones irregularly alternating between thin single-fold and wide multi-fold leaflets, 73-130 x 2.5-16 cm (interval 6-12 cm), distal pair 55-88 x 4-16 cm, connate for 8-18 cm, main veins 3-5 in single-fold leaflets, with scattered scales on minor veins, apices in distal pair long-dentate over 1.5-4 cm, in others acute. INFLORESCENCE interfoliar, erect, 0.7-1.2 m long, branching to 1 or 2 order(s), possibly occasionally multiple (personal observation under difficult circumstances, HB 4437), protogynous (HB 4525); peduncle 22-56 cm long, 2.2-3 x 1.3-2.2 cm diam., with dense red-brown scales; prophyll c. 32 cm long, c. 9 cm wide, with scattered scales; peduncular bracts 3 (always?) 20-62 cm long, 7-8 cm wide, with dense red-brown scales and a beak of up to 2 cm, the most proximal inserted only a few mm from the base of the peduncle and sub-woody; rachis 27-30 cm long, with 0-3 branched and c. 10 unbranched first order branches; rachillae dark brown, 22-60 cm long, with pistillate flowers occupying the proximal half to two-thirds of its length and single or paired staminate flowers the distal part; the interface between the two sexes mixed, not sharp, and occasionally with some triads here; also most pistillate buds at an early stage appearing to be flanked by staminate buds which later abort. STAMINATE FLOWERS yellow, the sepals 4.5-5.5 x 2.8-3.8 mm, keeled, acute, with ragged edges; petals connate for 2-3.3 mm, free parts 5-6 x 3.2-4.6 mm, with fleshy and thickened proximal margins; stamens and pistil connate for the proximal 2-3 mm with the petals; stamens equal, the filaments 2.2-3 x 1.2-1.3 mm, fleshy with wider base, angular, anthers 3-3.7 x 1.2-1.4 mm, dorsifixed, latrorse, slightly versatile, the locules slightly divergent; pistillode 4.5-5 x 1.5-1.6 mm. PISTILLATE FLOWERS with 4 bracts, 2.8-6 x 3-6 mm; between innermost bracts and sepals there is a ring of up to 2 mm high, thin, ?glandular hairs; sepals 7-10 x 5.5-7.5 mm, not keeled; petals 11-18 x 6-14 mm, with laciniate margins; staminodes 6, connate for the proximal 0.1-0.3 mm, triangular and flat, 0.6-1 mm high; ovary 12-15 x 5-6 mm, trifid for c. 3 mm, the inner surfaces papillose. FRUIT only seen empty, ellipsoid, 25-40 x 12-14 mm, topped by the persistent style/stigma mass. EOPHYLL deeply bifid; scale leaves two.</p></div>
