162 COL. GRANT—BOTANY OF THE SPEKE AND GRANT EXPEDITION. 
Hab. Madi &c., common, Feb. 1862, Col. Grant ! ( Asparagus, sp., App. Speke's Journ. 
650.) We have it also from Nubia, gathered by Petheriek, from Guinea by Dalton, Irving, 
and Barter, and from Zambesi-land by Kirk. 
(4% 5 feet high, common, with graceful Araucaria outline and pretty white flowers (February) ; the 
honey-bee now covers it. Guinea-fowl eat its seeds, consequently called * m'solankanga ” (Kin.) А’ 
variety, the “© mfgalamboottee ” (Kis.), has long, uniform, opposite branches, which ascend trees by their 
thorns. The root is masticated with salt, and the liquid squirted into the mouth of those who are suf- 
fering from sore eyes.—J. A. G.]
