Characteristics

Dioecious climbing shrub, sometimes treelet up to c. 8-10 m, or the basal part treelike, 2-3 m high, 3-4 cm diam. Branchlets (minutely pubescent to) glabrous, purple-brown. Petioles ¾-¾ cm, scattered-pilose, glabrescent. Leaves elliptic (sometimes slightly inequilateral), 9-17 by 3.5-6.5 cm, stiff-herbaceous, glabrous (young leaves often scattered pilose on the nerves beneath); glands conspicuous, on the lower surface mainly near the base; base acute, slightly decurrent; apex gradually acuminate, acumen short, blunt; nerves 4-8 pairs, at distances (along the midrib) of 1.5-3 cm, strongly curved, only the apical ones distinctly interarching. Inflorescences 1.5-2.5 cm long, short-stalked (sometimes dichotomously branched from the very base), rather laxly branched and many-flowered. Flowers 1 (male)-2 (female) mm long. Petals obovate, apex truncate to slightly emarginate, glabrous or the outer surface with some hairs near the base. Disk-lobes minute, 2-lobed, minutely tomentose. Pistil densely tomentose, in female flowers the ovary 3-celled; styles 3, confluent at the base, or stigma subsessile, 3-lobed, exceptionally 4-merous (G. STOCKER 656, Queensland). Fruits 1-2, 3(-2)-lobed, obovate, ¾-1¾ by 1-1¾ cm, slightly warty and with a few scattered, short, appressed hairs; suture narrow. Seeds glossy orange-red.

Leaves mostly elliptic, sometimes obovate, narrowed at apex but obtuse, 5–18 cm long, 2–7 cm wide, glabrous above, pilose to glabrescent below; veins 4–8 pairs; glands inconspicuous or absent; stipules caducous; petiole 2–7 mm long. Inflorescence lax, 0.7–2.5 cm long. Male flowers 1 mm long; female flowers 2 mm long. Sepals pilose outside, densly so on margins. Petals ovate or obovate, equal to or slightly longer than sepals, truncate to slightly bifid, white or yellow. Glands small, 2-lobed. Ovary densely tomentose; carpels 3; styles 3, or stigma subsessile and 3-lobed. Fruit 1–3 (rarely 4)-lobed, 7–17 mm long, 10–17 mm wide, glabrous or sparsely pilose, yellow or orange; suture narrow.
A bushy shrub up to 2 m tall. A shrub which climbs by attaching by roots from the nodes. Young shoots are hairy. The small branches are angular. The leaves are simple and oval or sword shaped. They are 12 cm long by 4 cm wide. They are bright green with wavy edges. The leaf stalk is 2-3 cm long. The flowers occur in clusters. They are small (0.5 cm across) and cream or green.
