J. Mulofwa with S. Simute and B. Tengnäs.  1994.  Agroforestry: Manual for Extension Workers in Southern Province, Zambia.  Swedish International Development Authority (SIDA), Regional Soil Conservation Unit (RCSU), Nairobi, Kenya . Tech. Handbook No. 4.  Appendix. 3.  199p.

Tonga: Mumpangala.

Lozi: Mukokoto.

Eng: Paperback (Acacia) thorn.

Ecology: An acacia with several variants, found from southern Africa to central north and west Africa at altitudes from sea level to 1,850 m. The tree is typical of the flat-topped acacias and locally common in munga woodland and eroded grasslands, occurs occasionally in mopane.

Uses: Fodder (leaves, fruit), tools (hoes), ink (gum).

Description: A medium sized deciduous tree, variable in height, reaching 18 m, branches spreading forming a rounded umbrella or low flattened crown. Bark: usually grey and rough, sometimes yellow-brown and flaking especially on branches, young branchlets golden hairy. THORNS: in pairs, straight and white, 1-10 cm, often absent over much of the tree. Leaves: compound and feathery, 6-23 pairs pinnae on a stalk to 15 cm, with very many tiny leaflets, no hairs or very hairy. Flowers: in round heads, white-cream-yellow, sweet scented. Fruit: large hanging pods 9-21 cm curved, thick and woody. Shiny brown or hairy, very slow to release 1-15 seeds embedded in a white spongy tissue.

Propagation: Seedlings, wildings, direct seeding.

Seed Info: Prolific seeder.

Treatment: Soak in hot water and allow to cool for 24 hours.

Storage: Seed can be stored if kept cool, dry and insect free.

Management: Coppicing, pollarding.

Remarks: The tree yields a clear gum of good quality suitable for ink making. Pods are eaten by cattle, buffalo, elephant, rhino and various antelopes. The leaves are browsed by game, but they contain quite large quantities of prussic acid at certain times, especially when wilted. The soft light wood is easy to work but not durable and of little value.
