Stems: 2-6 cm diam., smooth, green, prominently ringed, internodes 5-30 cm long. Leaves: 4-6, erect-spreading, pinnate, 1-2 m long; sheath 20-60 cm long or more, tubular, green, longitudinally striate-nerved, apex with a ligule on each side of petiole, these initially lanceolate and membranous and later deciduous or rotting away to leave a triangular base 1-2 cm long; petiole to 35 cm long, grooved near base and green above, rounded and pale below; rachis to 125 cm long, angled and green above, rounded below and with a pale band extending onto sheath; pinnae 20-26 on each side ofrachis, 25-40 x 2.5-5 cm, linear-lanceolate to lanceolate, slightly sigmoid or falcate or nearly straight, alternate or subopposite, long-acuminate, contracted basally and there with a ± raised light green bump above, a whitish midrib prominent above and below with 2 prominent primary nerves on each side ofthis, 2 secondaries between each of these.

Pistillate with 10-20 rachillae, these 20-35 cm long, 3 mm diam., very slightly longitudinally ridged, green and spreading in flower, reddish orange and drooping when heavily laden with fruits. Flowers: Staminate in moderate or ± dense spirals, 2.5-3.5 x 2.5-3 mm, oblong to depressed-globose, greenish yellow at anthesis ageing to brownish orange, slightly sunken; calyx 1 x 22.5 mm, deeply lobed, yellowish ageing to brownish orange, sepals free nearly to base and only briefly connate there, broadly rounded apically; petals 3 x 2-3 mm, ovate to deltoid, valvate, free nearly to base, spreading apically, ± fleshy, acute and slightly recurved apically; stamens 1-1.5 mm high, filaments short, anthers I mm long, brownish; pistillode to 2 mm high, columnar, slightly tapered apically, pale yellow. Pistillate in ± lax spirals, 3-3.5 x 2-2.5 mm, ovoid-globose, yellow, slightly sunken; calyx I x 2 mm, deeply lobed, greenish yellow, brown-margined, sepals connate only briefly basally, broadly rounded apically; petals 3 x 2.5-3 mm wide, triangular, imbricate nearly to apex, free, erect, acute apically; pistil to 3 x 2 mm, depressed-obovoid, green apically, styles short or lacking, stigma lobes short, recurved, thickened, dark.
