Characteristics

In the Flora area mainly a woody climber and usually with tendrils, 1–8(–10) m. long, but also sometimes a shrub or small tree 1–6 m. tall; young branches ferruginous pubescent or tomentose with adpressed or spreading hairs, later ± glabrous; root-branches at least in some specimens with spherical tubers up to 12.5 cm. in diameter hanging by thin rootlets 2.5–7.5 cm. long and only 3 mm. diameter.. Leaves (2–)3-foliolate; terminal leaflet narrowly lanceolate to ovate or oblanceolate; lateral leaflets lanceolate, subfalcate, oblong or ± rhomboid; all 2–14.5 cm. long, 0.8–6(–8.5) cm. wide, acute to obtuse or retuse at the apex, narrowly to broadly cuneate at the base, entire or slightly undulate, glabrous to sparsely pubescent above, ferruginous-tomentose to glabrous beneath; domatia sometimes present in axils of main nerves; petioles 1–4 cm. long; petiolules 0.2–2 cm. long; stipules ovate-triangular, 1.5 mm. long, 2 mm. wide.. Cymes lax or ± dense, the axes ferruginous pubescent or tomentose; peduncle 0.5–4 cm. long; pedicels 1–4 mm. long; bracts lanceolate, 0.5–2 mm. long, soon falling.. Calyx cupular, 0.7–1 mm. long, yellowish or densely ferruginous pubescent.. Petals yellow or green flushed red-purple, ovate, 1.5–2.5 mm. long, glabrous or pilose at apex.. Fruits black, globose, 0.6–1.5 cm. in diameter, glabrous.. Seeds 1–3, subglobose or flattened on one side when paired, 4.5–7 mm. in diameter, rugose and with shallow longitudinal furrow.

Leaves 3-foliolate; petioles up to c. 4 cm. long, indumentum as in young stems; stipules not seen; leaflet-lamina up to 12 × 6 cm., terminal leaflets narrowly lanceolate, lanceolate, oblanceolate or ovate, laterals lanceolate, subfalcate-oblong or rhomboid, apex obtuse or acute, margins entire or slightly undulate-lobed on the lateral leaflets, sometimes revolute, base from narrowly to broadly cuneate, from thinly pubescent to glabrous above, from ferruginous-or fulvous-tomentose to glabrous below; axils of main nerves sometimes provided with domatia; petiolules up to 2 cm. long.
A shrub which often scrambles. It can be a small tree. It can grow up to 7 m tall. The bark is grey and scaly. The young parts have woolly hairs. The leaves have 3 leaflets. The leaflets vary in size and shape. They can be narrow to oval to almost square. The upper surface is glossy dark green. The underneath has rusty hairs. The flowers are yellowish-green. The flower stalks have rusty hairs. The flowers are in small dense heads in the axils of leaves. The fruit have 2 lobes. They are 1-1.5 cm across and fleshy. They are black when mature.
Shrub or small tree to 3·3 m. tall with drooping branches or sometimes with sarmentose branches or more rarely a climber; young branches appressed-ferruginous-pubescent or densely fulvous-or ferruginous-pubescent or-tomentose, later glabrescent; tendrils tomentose, pubescent or glabrescent, often absent in herbarium specimens.
Shrub, creeper or small tree, up to 3 m high. Leaves 3-foliolate, leaflet lamina up to 120 x 60 mm, terminal leaflets narrowly lanceolate, lanceolate, oblanceolate or ovate, lateral leaflets lanceolate, subfalcate-oblong or rhomboid. Flowers yellowish green.
Inflorescences of rather lax or moderately dense cymes, branches from appressed-ferruginous-pubescent to fulvous-or ferruginous-tomentose; peduncle up to c. 4 cm. long; pedicels c. 1 mm. long; bracts up to 2 mm. long, lanceolate to ovate, very caducous.
Seeds 1–2, c. 5–7 mm. in diam., subglobose with a flattened side when seeds paired, rugose, with a shallow but distinct longitudinal furrow.
Calyx densely ferruginous-pubescent to fulvous-or ferruginous-tomentose.
Fruit ± black when ripe, 1–1·5 cm. in diam., globose, glabrous.
