continues to grow indeterminately, resulting in very long leaves, leaflets penni-veined, rhather long
and with many secondary veins. Inflorescences very long, hanging down. Fruits bright orange-red

dense terminal spirals; petiole 5-20 cm, woody, dark-coloured, glabresccnt to sparsely
hairy. Leaflets in up to 16 pairs, sometimes +/- alternate at base or rachis, 20-45(-55)
by (5-)8-12(-15) cm, oblong lanceolate or ovate when smaller, weakly bullate, glabrous
adaxially, +/- puberulous abaxially, base obtuse to subacute, apex acute to acuminate,
costae c. 15-24 on each side, tertiary venation scalariform; petiolules to 8 mm.
Inflorescence to 220 cm long, pendent; axis terete to weakly angled, weakly branched;
branches crowded towards apex, pilose, with up to 12 flowers each; bracts c. 6 mm
long, pubescent, caducous; pedicels c. 10 mm long, articulated with pseudopedicel.
Calyx 14-20 mm long and across, cupular to cylindrical, pubescent, red-brown, margin
truncate to irregularly 3- or 4-lobed. Petals 6-10, 30-45 by 4-7(-12) mm, creamy
pink. Staminal tube 25-40 by 6-7 mm, creamy white, glabrous without except on the
lobes, pilose within at base, margin entire or with lobes 4-6 mm long; anthers 16-30,
c. 5 mm long, rather recurved, connective somewhat pubescent. Disk flattened to weakly
annular, glabrous. Ovary c. 5 mm diam., 5- or 6-locular, pilose; style pilose in proximal
half or glabrous; stylehead c. 2 mm diam., capitate. Infructescence borne in axils of
last flush of leaves; axis to 3 m with terminal bunches of up to 60 fruits. Capsule to 12
cm diam., recurved, rostrate when immature, bright vermilion tomentose with irritant
deciduous hairs. Seeds 2.5-3.3 cm long, triangular in cross section; aril reddish, covering
inner edges of black testa. [from Flora Malesiana]
