Evergreen trees or shrubs up to 25 m high but usually smaller, trunk up to 1.5 m in diam., bark blackish grey, rough and fissured; branchlets and inflorescence tawny to ferruginous-pubescent. Leaves alternate, elliptic-oblong, obovate-oblong to oblanceolate-oblong, coriaceous, sparsely sericeous below or glabrescent, with a dull gloss above, 4.5-14 cm long and 1-3 cm wide, usually about 8 x 2.5-3 cm, apex obtuse to acute with a rounded tip, base broadly cuneate to rounded and often somewhat unequal.

Usually a medium-sized tree 10-15 m in height, occasionally reaching 25 m, with a dense dark rounded crown, giving excellent shade, or sometimes flowering as a shrub at only 3 m. Bark: dark blackish grey, rough, with deep longitudinal furrows; young branchlets, growing tips and young leaves pinkish. Leaves: alternate, oblong-elliptic or oblanceolate-elliptic, 4.5-14 x 1-4.5 cm, glossy dark green above, rather paler green below, turning yellow in autumn, almost hairless, 15-20 pairs of lateral veins ascending at about 45 degrees to the midrib, indistinct or slightly prominent below; apex broadly tapering to rounded; base tapering, sometimes square; margin entire, frequently closely wavy; petiole up to 1 cm long. Flowers: up to 1.2 cm long, cream to pale yellow, creamy grey hairs on the calyx and flower stalks, solitary in the axils of the leaves; floral parts in 4s or 5s (Oct./Nov.). Fruit: ovoid to almost round, fleshy, up to 2.5 cm in diameter, with very short soft hairs when young, losing these by maturity and becoming hard-skinned and yellow to purplish, persistent calyx with 4 or 5 wavy lobes covering less than a third of the fruit, the tips then curling back and not fully clasping it (Apr.-Sept.). Seeds: 3-6, reddish brown, mottled.
An evergreen tree. It grows up to 15-20 m tall. It can grow to 45 m tall in forests. It has a dense wide spreading round crown. The trunk sometimes has buttresses. Young branches have soft hairs. The bark is dark grey. The bark is smooth in young trees and becomes rough in older trees. The small twigs are pink. The leaves are simple. They are 4-17 cm long and 1.5-5.5 cm wide. The midrib is sunken on top and prominent underneath. The flowers occur as male and female flowers on separate trees. The male flowers occur in clusters and the female flowers occur singly. The fruit are round and 3 cm across. They have sweet edible pulp. The fruit are green and with hairs when young and become yellow or purple when ripe. They contain 4-6 seeds. The seeds are brown. They are oblong and flattened.

Environment

A tropical plant. It can grow in the tropical lowlands. It occurs in tropical Africa south of the Sahara. It grows in the Sahel. It grows in semi arid woodland. In occurs where the mean temperatures are between 16°C and 27°C. In Tanzania it grows between 350-1250 m altitude. It is more common where rainfall is 500-1270 mm per year. It does best on heavy soils. It often grows near streams and freshwater. It can grow on termite mounds. It can grow in arid places. It grows in Miombo woodland in Africa.
More
Riparian forest, more rarely on termite mounds or rocky outcrops or in dry semi-evergreen forest at elevations of 60-1,370 metres. Drier northern borders of the humid rain-forest zone especially in wet situations.

Cultivation

Plants are grown from seed. Seeds take about one month to germinate. Seeds can be covered in boiling water and left to soak overnight before planting. They can also be grown by coppicing and by root suckers. They can be grown by cuttings. Seeds need plenty of moisture to germinate well. Fruit are often collected from the ground but can be picked from the tree.
