    Habit
    Shrub, treelet or more often a woody climber 2–10 m. tall; young branches ferruginous pubescent, later glabrescent; sometimes with ‘potato-like’ roots (fide Tanner) presumably indicating it has tubers; tendrils fulvous pubescent or glabrescent.
    Leaves
    Leaves 3-foliolate or rarely 1-foliolate due to fusion of 3 leaflets; leaflets narrowly to broadly obovate, the laterals somewhat asymmetric, 1.5–9(–16) cm. long, 0.7–5.5(–8) cm. wide, truncate to subacute at the apex, cuneate at the base, the laterals often rounded on one side, toothed towards the apex with (1–)3–18 teeth or rarely ± entire, glabrous to densely ferruginous pubescent; petiole 0.2–4 cm. long; petiolules up to 5(–12) mm. long; stipules ± 2 mm. long, tomentose, falling almost at once.
    Inflorescences
    Cymes ± dense, the axes ferruginous pubescent or tomentose; peduncle 2–3 cm. long; pedicels ± 2 mm. long.
    Calyx
    Calyx ± 1 mm. long, ferruginous tomentose.
    Corolla
    Petals green, red or dark purplish, ± 2 mm. long, glabrous.
    Fruits
    Fruit black, globose, 0.7–1.1 cm. in diameter, glabrous.
    Seeds
    Seeds 1–4, greyish, ± globose or flattened on one side when paired, 5–6 mm. in diameter, somewhat rugose, with median longitudinal furrow.

    Leaves

Africa); nerves prominent below; petiolules up to 5 mm. long.
