Leaves consist of about 2-24 sessile leaflets each attached to the rhachis by a broad base. Leaflet blades about 18-23 x 1-6 cm. Terminal leaflets or segments wider at the base than any of the lateral leaflets. Major veins 4 or 5 per leaflet. Large, scattered, orbicular 'cells' visible with a lens. Leaflet apex praemorse, at least the broader ones.
Inflorescence about 38-80 cm long. Male and female flowers may appear to be in separate spikes but both are produced in each spike and the males shed following anthesis. Petals free in female flowers, fused in male. Stamens 7-10 in each male flower. Pollen white. Stigma bilobed.
Infructescence about 50-80 cm long. Fruits +/- cylindrical, red, orange or yellowish when ripe, about 8-18 x 3-8 mm. Calyx persistent at the base. Seeds about 12-15 x 2-3 mm, outer surface with fine longitudinal ribs. Embryo small, conical, about 1.5 mm long, located at the apex of the seed.
Seed germination time 40 to 364 days. Cataphylls 2 or 3, sheathing the stem. First pair of true leaves simple, pinnatisect and deeply bilobed. Veins parallel. At the tenth leaf stage: leaf compound with two broad-based, sessile, longitudinally veined leaflets or simple with a leaf of similar shape and texture. Leaf bases longitudinally striated and sheathing the stem.
