Hab. 7” S. lat. to 8° 30' М. lat., Col. Grant! 
The fragments do not admit of determination, and I leave them as in the Speke Appendix. 
[Found growing like a creeping bush, forming a network over the rocks about Madi, in December, 
when it was in flower. Stems round, an inch in circumference, smooth and green; branches opposite, 
leafless, very milky. Flowers radiate from the very tips of the branches. Natives сай it “ m”nyalla.” It 
is used ая а fence round villages of Central Africa. If planted singly, its branches spread widely and 
cover a good extent of ground; and its greatest height was 18 or 90 feet, the branches attaining 1 to 2 
inches in cireumference.—J. A. G.]
