Hab. Nubia, March 1863 (without fl. or fruit), Col. Grant ! 
[Native name “haraz.” A remarkably bushy tree, with trunk 8 feet in circumference; branches 
much contorted ; the younger ones have white bark, others black. Its leaves are eaten by goats, and the 
bark is used in curing leather. The natural outline of this tree is that of an umbrella. The ripe pods 
curl very much, are glossy, and of a dull red-yellow colour. Never met with till we reached 15° N. lat. ; 
but our men had seen it at Ulolee and Rukwa, in 7° $. lat. In Nubia there is a place on the Blue Nile 
called after this tree, “ Aboo-Haraz.”—J. А. G.] 
88. Acacia cATECHU, Willd.; Benth. in Hook. Lond. Journ. Bot. i. (1842) 510; 
Oliver, in Fl. Trop. Afr. ii. 344. 
Hab. Nile banks, March 1863, and Madi, Feb. 1863 (in leaf only), Col. Grant ! Also 
in Abyssinia and Zambesi-land, and common in India. 
[Native name “m’wombweh.” Stem 20 to 30 inches in circumference. Bark yellow and scales off. 
Thorns are black and hard as iron; they are the worst I saw in Africa. Pods red. This is the only tree 
to be met with upon the left bank of the Nile at 9° N. lat. From a distance it looks flattish-topped.— 
J. А.С.)

[Native name ** m'foomtamvool'ah." А handsome, graceful tree, with terminal, erect, jasmine-scented 
white flowers. Trunk 30 inches in circumference. Тһе pod is shining, smooth, and much veined. The 
leaves are in bunches or tufts beneath the flowers. Тһе natives steam their eyes and wash their faces 
with an infusion from its roots. This is one of their cures for ophthalmia.—J. А. G.]

ward through Afghanistan into India. 
[The largest trees I measured were 8 and 12 feet in circumference of stem, and grew upon high and 
dry ground, at 10° N. lat., on the Nile. We came upon a forest of them at 12° N. lat.; but, being 
almost in the water, they were not so thriving, and seldom grew straight. Again, we met with them 
at 28° М. lat., but 'observed them nowhere in Central Africa. Bark deep black, closely striated. ` Oe.
