Morphology General Habit
Glabrous shrub with stems 0.5–2 m. long; young branchlets subangular on upper part of internode, terete below, becoming terete.
Morphology Leaves
Leaves mostly opposite or subopposite; petiole apparently 2–8 mm. long, but the attenuate lamina expanding with age so that leaves become sessile; lamina coriaceous, dark green, paler beneath, ovate to elliptic, 5–14 cm. long, 2.5–7 cm. wide, ± acuminate at the apex, cuneate to rounded or cordate to attenuate base, 3-nerved from base.
Morphology Reproductive morphology Inflorescences
Umbels several in axils and at older nodes below, 3–6-flowered; peduncle 0–3 mm. long; pedicels 1–2 mm. long; bract ovate-triangular from a shallow saucer-shaped base, 1.5–2 mm. long.
Morphology Reproductive morphology Flowers Receptacle
Receptacle 1–1.5 mm. long.
Morphology Reproductive morphology Flowers Calyx
Calyx cupular, 1–2 mm. long, ciliate.
Morphology Reproductive morphology Flowers Corolla
Corolla 4–5 cm. long, deep crimson or wine-red (sometimes paler yellow-green when young), paler or greenish over vents, darker tipped; tube narrowed over the filaments, slightly expanded over anthers; basal swelling slight, not rupturing the calyx; tube papillate inside; lobes erect, 7–9 mm. long, upper expanded part linear-elliptic to linear-oblanceolate, 4–6 mm. long, 1 mm. wide.
Morphology Reproductive morphology Flowers Androecium Stamens
Filaments inflexed, flattened, slightly corrugated, the last 1 mm. hardened; anthers 2–2.5 mm. long.
Morphology Reproductive morphology Flowers Gynoecium Pistil
Style slightly expanded below stamens, forming only a slight neck, slightly fluted or winged; stigma capitate, 0.7 mm. across.
Morphology Reproductive morphology Fruits
Berry red or white, obovoid, 9 mm. long, 6 mm. in diameter, with a persistent calyx, sparsely covered in small pimples at least when dried.
Habitat
Evergreen forest; 950–1800 m.
Distribution
U2 U4 Cameroon to Sudan and south to Angola
