Stems prostrate or climbing up on grasses or bushes, longitudinally sulcate, glabrous or somewhat hairy, up to about 1 m long, occasionally longer when prostrate, often much longer when climbing. Leaves: blade 1.3-6 cm by 1.8-11 cm, very variable in shape and size but usually of 5-7, rarely 3-or 9, nearly free, linear or subfiliform to broadly oblanceolate, entire or coarsely pinnatilobed, acute, acuminate to subaristate or obtuse, lobes which are 2-5 cm, occasionally up to 8 cm long, and usually under 1 cm broad, usually more or less lepidote-scabrid with minute broad-based stiff sub-aculeate hairs especially on lower surface and along the margins; petioles always much shorter than the blades, usually under 2 cm long; stipuliform bract absent or suborbicular to flabellate, coarsely and more or less bluntly toothed or with very acute lobes with sometimes a subulate point, sometimes deeply and irregularly dissected, 0-1 cm long and broad but occasionally larger. Male Plant: pedicels solitary or fascicled, slender, under 2 cm long; receptacle narrowly obconical, 1-2 cm long; sepals subulate 1-2 mm long; petals greenish-yellow to olive, triangular to elongate-triangular, acute to more or less attenuate at the apex, usually 5-12 mm long. Female Plant: ovary subglobose to ellipsoid 6-17 mm long; calyx and corolla as in the male. Fruit ovoid-oblong to ellipsoid, usually more or less narrowed into the somewhat pointed apex, bright red when ripe, 2.5-3.5 cm long and 2-2.5 in diam. Seeds few, white, more or less 8 mm long and more or less 5 mm broad.
