Information
Tree (3)9-20 m. high, deciduous and usually flowering when quite leafless; trunk smooth except at the base where burned, with old bark peeling off in brown papery pieces, the young bark creamy-white to ochre-yellow or yellow-green; crown flat or rounded; young branchlets glabrous to pubescent. Leaves: rhachis clothed like the young branchlets, not hooked or clawed at the ends; pinnae 3-7 pairs; leaflets (4)7-13(17) pairs, somewhat asymmetric, 11-55 x 6-29(32) mm., ovate- to obovate-elliptic or ovate-oblong, rounded to subacute at the apex, glabrous to ± crisped-pubescent on both surfaces. Flowers white, usually produced before the young leaves, sessile or up to 1 mm. pedicellate; bracteoles spathulate, c. 2 mm. long, already fallen when the flowers open. Calyx 4-6 mm. long, sometimes slit unilaterally, densely brown-tomentellous on the lobes; tube glabrous to ± pubescent, occasionally with sessile glands. Corolla pale-green, 7-11 mm. long, ± brown-tomentellous on the lobes; tube glabrous to ± pubescent, occasionally with sessile glands. Staminal tube not or scarcely exserted beyond the corolla; filaments 1.5-4 cm. long, white below, greenish-white near the apex. Pod dehiscent, 10-35 x 2.5-5.2 cm., oblong, glabrous, brown, ± glossy, not or only obscurely venose. Seeds c. 10-17 x 8-13 mm., flattened.
Habitat
Characteristic of rocky hills and rock-outcrops and also, sometimes gregariously, on Kalahari Sand in Matabeleland (Pardy, loc. cit.)

Notes
A very distinct species with remarkable smooth papery-peeling bark and seeds usually larger than those of any other of our Albizia species. The flowers are usually produced when the tree is leafless, and specimens collected in this state, without notes about the bark, are liable to be confused with A. antunesiana Harms. The latter species may be distinguished (at least when dry) by the more prominent and raised nerves on the calyx-tube and by its smaller flowers.There is much variation in the indumentum of this species. Glabrous to sparingly pubescent leaflets appear predominant in our area, but in Jackson 2120 from Malawi, cited above, they are rather densely pubescent and smaller than usual.Six-month old seedlings collected at the forest-nursery at Kitwe, Zambia and said to belong to A. tanganyicensis, show the rootstock with a remarkable abrupt tuberous thickening c. 3-3?5 x 1?5-2 cm. It would be interesting to know if this is normal at this stage of development of the species.
