Glabrous pruinose perennial or sometimes annual; stem erect or sometimes decumbent at the base, 0.2–1.2(–2) m. high, simple or sometimes with a branch near the base.. Leaves petiolate; blade oblong to oblong-lanceolate, spathulate or triangular, (1–)2.5–4(–8.5) cm. long, (0.5–)1.5–2.5(–5.5) cm. wide, apex acute to obtuse, base cuneate, margins entire to shallowly crenate sometimes ± deeply 3-lobed (but not in E. Africa); petiole 0.3–1.2 cm. long (elsewhere lower and median leaves sometimes peltate with petiole 1.7–4.7 cm. long), subcylindrical, not broadened at the base, slightly constricted at the point of attachment and easily detachable from the stem.. Inflorescence a paniculate cyme up to 20(–48) cm. long; pedicels 2–5(–8) mm. long.. Calyx-lobes lanceolate or triangular, (0.5–)1–2 mm. long, 0.8–1.1 mm. wide, acute, connate at the base for 0.1–1 mm.. Corolla red or orange-red, yellowish to greenish in the lower part of the tube; tube (6–)7–10 mm. long, twisted in the upper part during fruiting and colour fading; lobes lanceolate or elliptic, (2.5–)4–5 mm. long, 1.5–2 mm. wide, very acute but not apiculate.. Stamens included within the corolla-tube; anthers with small apical glands, both episepalous and epipetalous ones broadly oblong, (0.3–)0.5–0.7(–0.8) mm. long, 0.4–0.5 mm. wide.. Nectary scales linear-subulate, 1–2.5(–3.5) mm. long.. Carpels linear-lanceolate, 4–6(–7) mm. long, terminating in styles 0.3–1 mm. long.
