COL. GRANT—BOTANY OF THE SPEKE AND GRANT EXPEDITION. 43 
[Native name * m'ceenango." Shrub: trunk about 15 inches in circumference ; branches boughing. 
The principal leaf-rib is winged, leaves very tender. Calyx yellowish green, minute, quarter the size of 
the corolla, which is pinkish or more yellow. Below each branch-axil there isa pair of flat, grey, crooked- 
down thorns at right angles to each other upon the stem, their length the eighth of an inch or longer. 
Its thorns tear one’s clothes while going through the woods. In flower at 3° N. lat. in December.—

Hab. Madi, Col. Grant! Occurs also in Abyssinia and westward to Nigritania. 
А singular variety (or distinct species?) with elliptical terete fruit about 1 in. long, the endocarp thin 
and crustaceous, was collected by Dr. Welwitsch in Angola. 
[Native name * m'choonchoo." Tree: trunk 6 feet in circumference ; branches rather weeping; bark 
black, closely and longitudinally striated; spines (January, at Madi) green with yellow tips; leaves a 
livid green and their surfaces glossy; inflorescence not always in the leaf-axils but above them: calyx 
green, corolla yellowish green; both hang slightly. Fruit filbert-size, but not angular; when this 
_ plum is sucked it tastes like an intensely bitter date. Natives of Madi eat it and extract oil from it by 
roasting; the oil is mixed with red clay and used as an unguent for the body. А+ 9? to 10° S. lat. the 
bark of young trees yields a very strong fibre of white colour.—J. А. G.].
