Characteristics

Herbaceous or (sub)woody perennial climber to 12 m long, hairy or (nearly) glabrous all over; dioecious. Leaves: petiole 0.5-3(-5) cm long; petiolules 0.4-2 cm long; blade membranous, blackish on drying; 3-or (pedately) 5-foliolate (i.e. the blade is primarily 3-foliolate and the lateral ones not divided or divided into 2 leaflets, the petiolule of the outer ones inserted on the petiolule of the inner), (5-)10-20 cm across, leaflets ovate or (narrowly) elliptic, 12(-15) by 5(-8) cm, glands 1 or 2, flat, 1-3 mm diam., usually towards the base of the outer margin of the outer leaflets, base (obtuse or) attenuate, apex obtuse or acute, 1-2 mm mucronate; midvein distinct, lateral veins 4-7 per side. Male inflorescences mostly many-flowered, broadly paniculate, axillary, 10-30 cm long, peduncle 1.5-4 cm long, branches (glandular-)pubescent or subglabrous, bracts linear, 0.5-2 mm long, the basal ones larger and 3(-5)-foliolate, to 1 cm long, flowers up to 5 (sub)fascicled, in condensed terminal racemes. Male flowers: pedicel slender, 5-10 mm long, (glandular-)pubescent or subglabrous; bud ovoid; perianth 5-8 mm diam., receptacle shallow, 1.5-2 mm diam., sometimes 5-saccate below sepals; sepals ovate-oblong, acuminate, c. 2 mm long; petals ovate, subobtuse or acute, 2.5-3 by (1.5-)2 mm, glabrous or puberulous; filaments free, c. 0.5 mm long; anthers less than 0.5 mm diameter. Female inflorescences paniculate, 2-10 cm long, up to 10-flowered. Female flowers: pedicel c. 10 mm, ovary subcylindrical, 7-8(-10) mm long, finely pubescent, styles short, stigma not lobulate. Infructescence 1-or several-fruited. Fruit 4-8 cm long, glabrous or pubescent, base narrowed or rounded, at apex 1.2-2.5(-3) cm wide; fruiting pedicel 1-2 cm long. Seeds many, ± unequal-sided star-shaped, 6-11 by 5-8 mm, margin (edge) of 5-7 coarse acute or blunt teeth, faces low tuberculate, wing 14-17 mm long to 8 mm wide.
