is very hard, and covered with the same markings as the stone of our peach. The kernel is large, brown, 
hard, with shining surface.—J. A. G.]

[Native name “ m”chenga ” or “m’nenga,” a small tree with graceful breezy foliage, growing upon the 
hills on the east-coast range, and also at 3° S. lat. Its bark is made into cylinders for holding grain, 
and also for kilts, cloths, roofing, &c.—J. А. G.] 
84. ? BRACHYSTEGIA TAMARINDOIDES, Welwitsch; Benth. in Linn. Trans. 7. с.; Oliver,

[Native name “meeombo,” a first-class tree, as it has so many uses. Tree fifty feet high; long, 
naked trunk 9 feet in circumference. Foliage deep green. The wood is considered good for building. Its 
bark, after being boiled and prepared, is made into white sheets or cloths worn by the natives at 10° S. 
They also make canoes, boxes, matches, and ropes from it. Its honey is considered very superior in flavour 
and whiteness. First met with thirty miles from the sea; afterwards in the interior it was frequent. It 
is so plentiful at 6° S. lat. that our temporary huts were roofed with its bark, and my plants were pro- 
tected by planks of its bark, which answered admirably, being light and stiff.—J. А, G.]
