Derivation of specific name
The Mopane tree typically attains a height of five to twelve metres, assuming a generally rounded growth form. The trunk is dark grey or brownish, displaying longitudinally fissured bark. Alternate leaves are compound, resulting in the characteristic "butterfly shape". The hairless leaflets are 4.5 to 9.0 centimetres (cm) long and 2.5 to 5.0 cm wide; moreover, these leaflets are asymmetric with pointed tips, and yield a turpentine aroma whten crushed. Petioles are 1.5 to 4.0 cm long. Small whitish flowers are arrayed in short sprays, and a kidney shaped fruit is produced in a papery pod. Leaves are austral winter deciduous.

Colophospermum mopane, commonly called mopane, mopani, balsam tree, butterfly tree, or turpentine tree, is a tree in the legume family (Fabaceae), that grows in hot, dry, low-lying areas, 200 to 1,150 metres (660 to 3,770 ft) in elevation, in the far northern parts of southern Africa, into South Africa, Zimbabwe, Mozambique, Botswana, Zambia, Namibia, Angola and Malawi. The tree only occurs in Africa and is the only species in genus Colophospermum. The species name mopane is taken from the local name for the tree.
It is found growing in alkaline (high lime content) soils which are shallow and not well drained. It also grows in alluvial soils (soil deposited by rivers). In small portions of South Africa and larger adjacent areas of Botswana and Zimbabwe, the trees tend to vary between 4 and 18 m (13 and 59 ft), often called "mopane scrub" (shrub) but also sometimes taller and forming woodland, where further north the trees are taller and form tall woodlands referred to as cathedral mopane. This tree does not grow well outside hot, frost-free areas with summer rainfall.
Its distinctive butterfly-shaped (bifoliate) leaf and thin seed pod make it easy to identify. For human use it is, together with camel thorn and leadwood, one of the three regionally important firewood trees. The name Colophospermum is Greek for "oily seed", in reference to the resinous seeds. The part of the name, colophos, apparently refers to the strong turpentine smell of the resin. Colophon was the birthplace of Homer in Ionia, and was famous for its rosin, a substance obtained from turpentine or the gummy exudate of some trees.
Mopane wood is one of southern Africa's heaviest and is difficult to work because of its hardness. However, this also makes it termite resistant. For this reason it has long been used for building houses and fences, as railway sleepers and as pit props. The termite-resistance and rich, reddish colouring also make it popular for flooring. Outside Africa, mopane is gaining popularity as a heavy, decorative wood, its uses including aquarium ornaments, bases for lamps or sculptures, and garden accents.
It is also increasingly being used in the construction of musical instruments, particularly woodwind. Suitable quality African blackwood (Dalbergia melanoxylon), traditionally used for clarinets, is becoming harder to find. Mopane is fairly oily, seasons very well with few splits or shakes, and produces instruments of a warm, rich tone.
The tree is a major food source for the mopane worm, the caterpillar of the moth Imbrasia belina. The caterpillars are rich in protein and are eaten by people. The tree also acts as a foodplant for a wild silk moth, Gonometa rufobrunnea. Cocoons of the moth are harvested as wild silk, to make cloth.
