Hardwickia mopane (J.Kirk ex Benth.) Breteler (1997)
Colophospermum mopane, commonly called mopane, mopani, butterfly tree, turpentine tree, or balsam tree, is a tree in the legume family (Fabaceae), that grows in hot, dry, low-lying areas, 200 to 1,200 metres (660 to 3,940ft) in elevation, in parts of Southern Africa. The tree only occurs in Africa and is the only species in genusColophospermum. Its distinctive butterfly-shaped (bifoliate) leaf and thin kidney-shaped/nearly semi-circular seed pod make it easy to identify.
Though hard and dense and difficult to work with, it is valued timber in all sorts of construction due to its termite tolerance. Together with camel thorn and leadwood, it is one of the three regionally important firewood trees, due to the enduring heat,[clarification needed] and these woods are also some of the preferred use culinarily for braai.
Range and habitat
The two papilionaceous leaflets are mirror images of one another, and are borne on a common petiole.
The mopane is found on low-lying ground from 200 metres (660ft) (Mozambique) to 1,200 metres (3,900ft) (Zimbabwe).
While it prefers slightly acidic deep clay soil that are friable and permeable, it also grows in alkaline (high lime content) soils which are shallow and not well drained. It also grows in alluvial soils (soil deposited by rivers). Where it occurs, it is often the dominant tree species, frequently forming homogeneous stands.
Within the Zambezian region described above, the trees' height varying considerably, and larger, single-stemmed trees of 10 to 15m (33 to 49ft) are found in open savannah woodlands on the (sandy) alluvial soil, forming canopy woodlands, and even reaching 18m in height for the so-called "cathedral mopane" of Zambia. The same tree is also found stunted as (multi-stemmed) shrubbery about 1 to 2 or 3m (3.3 to 6.6 or 9.8ft) in clayey soil or impermeable alkaline soil. Thus water or drainage seems to be a cause factor for stunting, though other causes have been hypothesized. These stunted growths are sometimes called "mopane scrub" (for shrub). The shrubs will not transition into tall woods.
This tree will not grow well outside hot, mostly frost-free areas with low to moderate rainfall (as low as 100mm per year, or averaging 400–500mm per year).

Mopane wood is one of southern Africa's heaviest, with an average density range of 0.990 to 1.230g/cm3 (61.8 to 76.8lb/cuft) at 12% moisture. and is difficult to work because of its hardness. However it is also termite resistant making it one of the most preferred local timbers for construction, and 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 parquet flooring. Outside Africa, mopane is gaining popularity as a heavy, decorative wood, its uses including aquarium bogwood ornaments, similarly as driftwood decor for terrariums or gardens, or bases for lamps or sculptures.
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. Clarinets made of mopane are offered by the manufacturers Schwenk & Seggelke, Wurlitzer, F. Arthur Uebel and Buffet Crampon.
Mopane twigs been traditionally used as a sort of tooth brush (chewing stick to clean teeth), and the leaves for folk remedy in healing the wound after ritual extraction of teeth. Various parts of the tree (seed, leaf, bark, root) are used in the traditional medicine of Southern African for a wide range of symptoms.
The bark to make twine or rope and for tanning leather, The wood is also used to make charcoal and for braai wood.
Food source
The tree is a major food source for the mopane worm, the caterpillar of the mothGonimbrasia belina. The caterpillars are rich in protein and are eaten by people. The mopane worm is rich in crude fats and contains vitamins and minerals, such as iron, calcium and phosphorus. Another edible caterpillar is that of Gynanisa maja (speckled emperor moth; chipumi in Bemba) which also uses mopane as host tree.
And when infested with the "mopane fly" or "mopane psyllid" (Retroacizzia mopanisyn.Arytaina mopani ) that feeds on the tree, the tree produces edible wax-like gums on its leaves called "mopane manna" which are collected and eaten by humans and monkeys.
The tree also acts as a foodplant for the wild silk moth, Gonometa rufobrunnea. Cocoons of the moth are harvested as wild silk, to make cloth.
The Mopane worm creates employment and serves as a source of income for the majority of rural women. Harvesters sell it in villages, towns or to the trader.
The genus name Colophospermum is a compound from Greek kolophon[ios] "resin" + Latin spermum "seed". The former derives from Colophon", which was the birthplace of Homer in Ionia, famous for its rosin, and is a reference to the seed's aromatic (turpentine-smelling) component.
The species name mopane is from its common name in Bantu languages for the tree throughout most of its range. Thus the nomenclature, starting with areas in or around South Africa are: mohlanare, mopane in Northern Sotho/Sepedi (northern Transvaal, current Limpopo province), mophane, mopane in Tsuwana (western Transvaal, northern Cape, Botswana) but nxanatsi in Tsonga (eastern Transvaal). It is known as mopane, tsanya in Chichewa (Malawi), mopani, mupane in Lozi (fmr. Barotseland, western Zambia), mupanyi in Thimbukushu (Namibia), omutati in Herero (Namibia, Botswana), omufiadi in Ovambo (southern Angola, northern Namibia).
Also spelt mupani, mopani. In Afrikaans it goes by mopanie or mopaniehout "mopanie wood" or terpentynboom "turpentine tree". It is called musharu in Shona (Sabi valley, Zimbabwe), chanate in southern Mozambique, and mutiati in Umbundu (Angola).
