Order: Brassicales. Family: Capparaceae

Roots

Description
It is a small to medium-sized evergreen tree up to 7 m tall. It has a dense, round to spreading crown. It can be a single-stemmed, relatively high-branching tree with a crooked or twisted stem (up to 8 m). Over much of the Kalahari and the Karoo, it is a small rounded shrub.
The conspicuous, whitish bark can make the tree look as if it has been whitewashed. It is often pitted and folded, and may have tiny holes. In some areas older bark becomes yellowish or blackish, and can be flaky.
The leathery leaves are arranged in clusters in bunches of 4 - 5 on both older branches and on short, spiky side-branchlets. On new growth they may be scattered alternately. They have smooth margins and a short leaf-stalk (Leaf variable, usually 20 - 60 x 4 - 20 mm).
The flowers are borne in clusters on short shoots. They are small, sweet-scented, greenish-yellow and are usually on older growth. They occur singly, or in small, dense clusters, on short side-branchlets usually on older wood. Flowering trees have a striking yellow-green tinge. The flowers appear from July to November, but generally start in August, depending on rainfall (4 mm diam.)
Fruit grows in bunches along the fruit-stalk (Oct - Mar) (10 mm diam.).

Habitat
It is found in the drier parts of southern Africa, in areas of low rainfall.

Distribution
Botswana, South Africa (Limpopo, Gauteng, North-West, Free State, Northern Cape and KwaZulu-Natal), Swaziland. It also extends into Zambia, Zimbabwe and Mozambique.

Etosha National Park, Namibia

Description
A conspicuous, erect, deciduous tree up to 7 m high, bearing a succulent, often bottle-shaped main branch up to 1 m in diameter. The roots are fleshy. The bark is smooth, brown to silvery copper, with a shiny green sheen, and resinous. The leaves (tending to droop) are alternately arranged, twice-compound and up to 0.6 m long with up to 4 pairs of pinna, each with up to 7 pairs of opposite, oval leaflets and a terminal leaflet. The leaflets can grow up to 25 mm long.
The white flowers are borne in branched axillary sprays (panicles), each up to 3 mm in diameter with 4-5 petals. They are followed by grey-brown, three-angled pods, up to 400 mm long, which split along three valves, releasing the winged seeds. Flowering time: mainly November to May (fruiting October to May).

Distribution
Indigenous to Namibia and Angola. Widely distributed in Namibia from the escarpment mountains northwest of Keetmanshoop to the Kaokoveld in the north, and further north into Angola.

Habitat
Its habitat consists mainly of desert or arid savannah vegetation. In the north it grows in dry mopane woodland (Colophospermum mopane). At Epupa Falls, beautiful examples occur on the rocky island and can be seen growing together with the baobab (Adansonia digitata), Commiphora virgata, Euphorbia subsalsa, Adenium oleifolium and Pachypodium lealii. The soil is sandy, rich in gravel and may be alkaline, neutral to slightly acid. The trees usually only grow on the slopes of mountains and hills and Etosha is the only place where the trees grow in such numbers on the plains.
