Herbaceous or woody climber, 1–10 m long, the flowering stems often hanging down, rarely epiphytic; stems often pink or reddish, rooting at the nodes, becoming woody with age; indumentum of simple hairs.
Morphology Leaves Stipules
Stipules narrowly triangular, 1–3 × 0.4–0.8 cm, apex acuminate, glabrous or with hairs at the base, caducous.
Morphology Leaves
Leaves green to reddish, thin to slightly fleshy, obliquely ovate, 4–13 × 2–8.8 cm, base obliquely cordate, margin denticulate to serrulate, larger teeth interspersed with numerous smaller teeth, apex acuminate; venation palmate; glabrescent above and below, venation tomentose beneath; petiole usually red, 2–12 cm long, junction with the lamina densely tomentose.
Morphology Reproductive morphology Inflorescences
Inflorescence axillary, unisexual or rarely bisexual, a dichasial cyme, many-flowered; bracteoles absent. Female inflorescence with 2–7 flowers; peduncle 0.7–3 cm long; bracts similar to those in male inflorescence, caducous. Male inflorescence with 4–15 flowers; peduncle red or pink, 0.5–6 cm long; bracts weakly boat-shaped, elliptic to ovate, 1.3–2.5 cm long, chartaceous, with conspicuous veins, caducous; pedicels 1.1–2.6 cm long.
Morphology Reproductive morphology Flowers
Female flowers: tepals 2–4, white to pink, the outer obovate to nearly orbicular, 1.7–3.3 ×1.4–3.5 cm, the inner 1–1.7 × 0.4–0.6 cm, caducous or absent; styles 5, forked at the apex, spirally twisted twice, glabrous; stigmatic band yellow; ovary ellipsoid, 5-locular, without wings, surface verrucose; placentation parietal. Male flowers: tepals 4, white to pink, the outer suborbicular to broadly elliptic, 1–1.9 × 1.1–1.4 cm, the inner narrowly obovate, 0.8–2.6 × 0.2–0.4 cm; stamens yellow, many, ± 100, filaments free, anthers elliptic to shortly oblong, 0.4–0.8 mm long.
Morphology Reproductive morphology Fruits
Mature fruits greenish with white warts, fleshy, ellipsoid, 1–3 cm long, 0.8–1 cm in diameter, up to 4.5 cm including the extended stipe, terete in cross section, with narrow longitudinal furrows, verrucose (or warty), indehiscent, with persistent styles.

Ecology
Moist forest, swamp forest, may be locally common; 1350–2800 m .
Conservation

Note
Flowers are often described as being fragrant, an unusual characteristic in African Begonia. It is strange that this plant does not seem to occur on Mt Elgon.
