nodes and several pods; pod 2-valved, dehiscent, 10-30 c.m. long, consisting of 1-6 globose cells separated by narrow constrictions, and having a 5-10 c.m. barren 
portion at the base, and a 3 c.m. acute point. Seed scarlet, 2 c.m. long, 12-14 m.m. wide. Present but scarce in the M’Chopes and Inhambane districts (extra- 
tropical); also in Quelimane, Magenja da Cosia, Nhamacurra, and in the Zambesi and Shire Valleys.

98. CAJANUS. Two upper calyx-teeth connate. Standard round, reflexed. Upper stamen free, others connate. Ovules many. Style glabrous. Pod linear, compressed, 
2-valved, dehiscent, with transverse constrictions. Leaves 3-foliate. 
C. indicus, Spreng. Fern, names — 4, Kolokoto; 6, Ndoti : to, Boere. A shrub 3-4 metres high, frequent in cultivation and often naturalised where cultivation has been 
abandoned. Leaflets oblong, 5-8 c.m. long, pointed, glabrous above, canescent below. Racemes few-flowered; standard brownish yellow. Legume 8 c.m. long, 
15 c.m. wide, pointed, 3-6 seeded, pubescent. Seeds used in native cookery, like lentils. Never timber size, but its wood is used further north for the production 
of fire by friction. It occurs throughout the Province and is cultivated by Indians in Natal. 
99. PTEROCARPUS. Unarmed trees, having imparipinnate (or simple) leaves, with alternate side-leaflets; terminal or axillary racemes or panicles of yellow flowers; and 
distinctive usually 1 -seeded pods having a wide and nearly circular membranaceous wing surrounding each. Calyx turbinate, the upper 2 teeth somewhat 
connate. Corolla yellow; standard rounded, keel petals nearly free; stamens connate in a slit tube or with 1 stamen more or less free. Ovary with several 
ovules; seed 1 (or sometimes 2) seeded. Pod indehiscent, somewhat compressed, sometimes bristly, with a wide thin wing all round, and the style lateral or even 
near the stalk. 
P. erinaceus, Poir. Fern, names — 4, Thondo; 10, Imbilo; 11, Moqombire-bire; 15, Shuiaan. A more or less deciduous tree 15-20 metres high, with straight bole 
30-45 c.m. diameter spreading crown, and pubescent branchlets. Leaves unequally pinnate; rachis slender, 20-30 c.m. long ; leaflets 9-13, sub-opposite or alternate, 
4-8 c.m. long, elliptical-lanceolate to obovate, glabrous above and ultimately glabrous below. Flowers in terminal panicles with racemose branches. Pods often 
several together, each with a firmly membranaceous wing an inch wide all round, nearly circular, 10 c.m. wide (including wing); the stigma near the stalk; the 
central seed-bearing portion 12 m.m. diameter and densely echinate with bristles 10-12 m.m. long; smaller bristles or hairs are on the inner part of the wing and 
towards the stalk and stigma ; other portions of the wing are glabrous and more or less reticulated. 
In the “ Flora of Tropical Africa ” P. angolensis is included as a synonym, and concerning this Miss L. S. Gibbs says “P. angolensis A.D.C. which has 
often been quoted as a synonym of P. erinaceus, Lam., is easily distinguished by the larger flowers and much larger fruit, which has more bristles in the centre and 
a broader wing.” All the trees seen throughout Mozambique Province appeared to be alike, and with less variation than most species. Present though not 
abundant throughout the extra-tropical parts of the Province, abundant through the tropical districts and in some places as in the Robe Forest, near Arenga, 
Magenja da Costa forming almost pure forest. A valuable and durable timber, found in great abundance, and certainly the most valuable asset the Province has in 
its tropical forests. It extends into Natal, Swaziland, the Transvaal, and to the West Coast, and (including P. angolensis) from the coast to the Matopos.
