E. Wahlbergii, Harv. A glabrous climber, leaves with 2 pairs of pinnae, each with 4-18 pairs of linear oblong leaflets 1-2 c.m. long. Inflorescence in axillary or 
terminal spikes or these together forming a panicle. Flowers red. Pod flat, 10-15 c.m. long, 3-4 c.m. wide, with constrictions at the margins between the seeds. 
Rovuma River. 
E. Kirkii, Oliver. A glabrous climber, with about 4 pairs of pinna;, each with 10-12 pairs of oblong leaflets 2 c.m. long, 6-7 m.m. wide. Flowers white, in dense spikes. 
Pod 40-60 c.m. long, 7-9 c.m. wide, the joints broader than long, the valve swollen over the seed. Zambesia, from the coast to Tete. Dr. Kirk. 
E. sudanica, Schw. A bush with leaves 30 c.m. long, 5-8 pairs of pinna;, 14-20 pairs of oblong glabrous or thinly pubescent leaflets 2 2 5 c.m. long. Spikes 6 to 15 
c.m. long, flowers )ellowish, almost sessile. Pod 20-35 c - m - l° n g. 3'5 c.m. broad, constricted on both margins between the seeds; seeds many, 115 c.m. diameter, 
the sections of the pod much wider than long. Zambesia. 
E. natalensis, Benth. Vern. names 4, i-kano, and Kakatlwaan. A vigorous climber, the stems and petioles armed with hooked prickles; leaves with 5-7 pairs of 
pinna each with about 12 pairs of oblong leaflets. Pod 12-15 c - m > long, 3 c.m. wide, glabrous, many-seeded. A forest weed, making such a dense mass as to kill 
the trees on which it hangs, and most difficult for a person to get through if near the ground. Frequent in the extra-tropical parts of the Province. 
121. TETRAPLEURA. Trees with alternate, bi-pinnate, glabrous leaves, spicate inflorescence, stamens 10, anthers with an apical gland and 4-sided indehisccnt legumes. 
Several species are West African, as is also the following 
T. obtusangula, Welw. M.S.S. (“Flora of Tropical Africa,” II., 331). Vern. name — 10, Mseriale. An erect tree 10-15 metres high, with stem 30-45 c.m. diameter, 
and abundant glaucous fernlike foliage, as seen from below. Leaves 2-pinnate, with 3-4 pairs of pinnae, each having about 8 leaflets on each side, alternate, shortly 
petioled, obovate or elliptical, 1*5-2 c.m. long, 1-1*5 c - m - wide, green above, glaucous below, the rachis and petiole slender, wiry, brown, glabrous; the secondary 
rachis swollen at the base. Inflorescence not seen. Pods 7-12 c.m. long, 2-2*5 c.m. wide, 4-sided or somewhat 4-ridgcd, pointed brown, firmly leathery, 
several-seeded, and showing a nearly square section. Frequent in the forests of Magenja da Costa and Nhamacurra, highly ornamental, and said to have a hard, 
black, useful timber.

122. PROSOPIS. Trees with bi-pinnate leaves, spicate inflorescence, and subterete indehiscent pods with septa between the seeds. Mostly American ; the pods of some 
used as cattle-feed. 
P. (?) Kirkii, Oliv. Unknown to me; described in “Flora of Tropical Africa” as “A large tree ; extremities unarmed, glabrous or obsolete-puberulous, slightly furrowed 
when dry, with pale ashen bark. Pinnae 6-7 jugate, with a sessile gland between the pinna;, rachis puberulous above. Leaflets 10-17 jugate, subsessile, oblong, 
obtuse, minutely pubescent, inch long, 1 line, more or less broad. Flowers in solitary axillary spikes 4-6 in. long (apparently insect-punctured in our 
specimens). Legume 5-8 in. long. 1 in. broad, flat, coriaceous, circinate, with a short hooked apiculus. Seeds compressed, ovate, with a shining testa and 
faint areole on each side, separated by narrow interposed cellular partitions of the endocarp. Albumen o. Shire River, Zambesi-land ; Dr. Kirk.” 
123. DICHROSTACHYS. Flat-topped trees or shrubs, closely resembling in general appearance species of Acacia, and having axillary single spines often present, 
2- pinnate leaves, numerous small sessile leaflets, spicate inflorescence, the upper flowers hermaphrodite, the lower flowers barren, and the pods twisted, linear, flat, 
indehiscent or opening irregularly ; seeds albuminous. 
D. nutans, Benth. Vern. name — 4, Sasana. A small tree 2-4 metres high, having solitary axillary straight slender spines 5 c.m. long on the larger branches, and 
occasionally short hooked stipulate prickles in pairs on the slender twigs. Leaves bi-pinnate, 3-5 c.m. long, 3-4 c.m. wide ; pinna; 3-5 pairs, leaflets 7-12 pairs, each 
3- 5 m.m. long, linear. Spike 7-10 c.m. long, lower part nearly an inch wide, with pink filaments, upper part narrower, fertile, yellow. Pods numerous in clusters, 
much twisted, 1 c.m. wide, 5-12 c.m. long. Abundant in the thorn-veld of the southern part of the Province, extending also through Natal ; in the northern part of 
the Province it is present, but less abundant, and it occurs widely distributed through Tropical Africa. Timber very hard and dark, but too small to be of other use 
than fuel. Bark very rough, dark grey, deeply fissured, and more or less netted in deep ridges ; foliage deep green.
