Characteristics

Shrubs or trees usually no more than 10 m. tall but reported occasionally to 25 m. and with trunks 5–7 dm. thick; wood very hard and heavy; bark deeply checked and tending to shed in sheets.. Younger branches conspicuously lenticellate; branchlets 2–20 cm. long, leafy, glabrous to densely pubescent with short spreading whitish hairs.. Leaves opposite or nearly so; earliest (lowest) blades of emerging branchlets smallish, elliptic-obovate and blunt, later ones larger, elliptic to ovate-oblong, acute (2–)3–5(–9) cm. long, (l.5–)2–3.5(–6) cm. wide, at the base cuneate or usually rounded, at the apex blunt to acute, green above and glabrous or minutely pubescent near the midrib, beneath slightly paler and microvesiculate and glabrous to densely pubescent with short whitish hairs, on each side of midrib with 6–8 (–9) secondary nerves; petioles (4–)8–10(–13) mm. long, glabrous to pubes-cent.. Stipules intra-axillary, 2–4 mm. long, subulate, united about half the length, all but the basal 0.5–1 mm. quickly deciduous.. Flowers solitary or usually in fascicles of 2–6 in the axils; pedicels 3–5(–7) mm. long in flower, 4–7(–10) mm. in fruit.. Sepals 2–3 mm. long, spreading to reflexed at anthe-sis.. Petals 1.8–2.2 mm. long, spreading or weakly arcuate-ascending.. Style 1 mm. long, bifid a fourth to a third the length.. Disk free from the ovary though thick near its base.. Fruit 12–20 mm. long, 7–11 mm. thick, yellow.. Fig. 10.
More
A tree. It grows 12-18 m tall. It usually loses its leaves during the year. The branches are spreading. The crown is dense and round. The leaves are simple and nearly opposite. They are dark green above and paler underneath. They are 2.5-10 cm long and 8 cm wide. They are oval with pointed tips. The flowers are in small stalked clusters in the axils of leaves. The fruit are like small pointed plums. They are about 2 cm long. They are yellow or red. They have a sweet yellow pulp and a kernel with 2 seeds. The fruit are edible.
Leaves alternate towards base of shoots, opposite to subopposite distally; lamina 5–11 × 3–6·6 cm., ovate or obovate-elliptic, midrib and 5–8 pairs of secondary nerves extending to leaf margin very prominent beneath and tertiary venation prominent and subparallel in adult leaves, glabrous or sparingly pubescent especially along the nerves above and below; petiole 5–15 mm. long, glabrous or pubescent.
Tree up to 20 m. or more tall with dense rounded crown; bark very rough and tending to exfoliate in large pieces; branchlets pubescent or glabrous.

Environment

A tropical plant. It grows in dry forest. It grows at low altitude in South Africa. In East Africa it grows from sea level to 1,600 m altitude. It is damaged by frost or cold winds. It is drought resistant. It grows in areas with an annual rainfall between 300-635 mm. It can grow in arid places. It is often on termite mounds. It grows in the lowlands and along rivers. It grows in Miombo woodlands.
