This Larkspur inhabits the mountains of Eastern 
tropical Africa, chiefly in the Uganda Protectorate, at 
elevations of 6,000 to 8,000 ft., and the Hon. Walter 
Rothschild imported it from Mount Elgon. The plant 
actually figured was from Mr. James O’Brien’s garden at 
Harrow-on-the-Hill, and Miss O’Brien made the drawing 
illustrating the habit. Mr. J. Thomson first discovered it 
in Lykipia, in the Masai Country, in 1884, and there are 
also specimens in the Kew Herbarium, collected by Bishop 
Hannington, Mr. A. Whyte, Sir Evan James, and Mr. 
C. F. Elliott. The plant figured was cultivated in a 
pot; Mr. O’Brien is of opinion that it may prove to be 
hardy. 
Descr.—A_ perennial herb, hairy in nearly all parts. 
Stems as grown in a pot about 5 ft. high, slightly 
branched. Leaves palmately divided into 38-7 primary 
segments varying from % to nearly 1 in. across, 8—many- 
lobed ; lobes acute; petioles of the lower leaves 6-8 in.
