    Stipules
    Stipules narrowly triangular, 1–3 × 0.4–0.8 cm, apex acuminate, glabrous or with hairs at the base, caducous.
    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.
    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.
    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.
    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.
    Figures
    Fig. 2, p. 5.
    Ecology
    Moist forest, swamp forest, may be locally common; 1350–2800 m .
    Conservation
    Least concern (LC); widespread.
    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.
