Characteristics

Shrub 30–60 cm tall with pale brown branches with ± peeling bark; youngest parts with dense raised lenticels the same colour, sometimes papillose-puberulous (not in E Africa?).. Leaves ± subcoriaceous, narrowly oblong to narrowly oblanceolate, 1.7–7.5(–12) cm long, 0.6–2 cm wide, acute to narrowly rounded at the apex, cuneate to narrowly rounded at the base, crenate-serrate at the margin, the teeth incurved or directed upwards; midrib, lateral veins and tertiary venation distinctly prominent on both surfaces; petiole short, 1–2 mm long, thick and channelled; stipules triangular, 2–3 mm long, striate, very soon deciduous.. Flowers borne on leafless branches, (1–)2–4(–6) on very short spur-shoots ringed with close bract scars; buds globose; pedicels 1–1.5 cm long extending to 1.3–2 cm long in fruit, jointed at base or 3–4 mm from base.. Sepals broadly elliptic or round, 5–8 mm long, 4–6 mm wide, becoming red and expanding to (9–)15–17 mm long, 8 mm wide in fruit.. Petals yellow, obovate, 9–10(–15) mm long, 6(–14) mm wide.. Anthers 2.5 mm long, opening by apical slits; filaments 2 mm long.. Carpels 5; styles completely joined; stigma ± capitate.. Drupelets green but presumably turning black, ± globose, (5–)8 mm diameter.. Fig. 5 (p. 32).
More
Leaves petiolate; lamina (6) 8–12 × (1) 1·2–2 cm., narrowly elliptic or narrowly oblong-elliptic, obtuse to subacute at the apex, with margin ± densely spinulose-serrulate, attenuate to cuneate or truncate at the base, herbaceous to chartaceous, with spreading or somewhat ascending lateral nerves (main and subsidiary almost equally prominent) and densely reticulate tertiary venation more prominent above than below; petiole c. 1 mm. long, stout, grooved.
Flowers (1) 2–5 (6) in a condensed racemose or pseudumbellate axillary inflorescence; pedicels 1–2 cm. long in fruit, articulated at the base or within 1 mm. of it, glabrous or very sparsely puberulous.
Shrublet up to 0·6 m. high, with brown bark; shoots erect, little-branched, shallowly striate, yellowish-white, densely lenticellate but not markedly pustulose, papillose-puberulous (at least in part).
Sepals 5–8 mm. long in flower, elliptic or oblong, rounded, becoming crimson, 9–13 mm. long, slightly convex and accrescent or ± spreading in fruit.
Stamens with anthers 2·5 mm. long, 2/3 as long to as long as the filaments, straight, dehiscing by longitudinal slits.
Petals orange to orange-yellow, 8–15 x 7–10 (14) mm., rhombic-subcircular, unguiculate.
Drupelets 5–7 x 4–5·5 mm., subglobose, inserted near the base; embryo slightly curved.
