COL. GRANT—BOTANY OF THE SPEKE AND GRANT EXPEDITION. 111 
Hab. Unyoro, No. 555, Aug. 1862, Col. Grant ! 
To this species probably may be referred a specimen in fruit only, Gomphocarpus no. 6 of App. Speke’s 
Journ. 640. The follicle is inflated and shortly and softly pubescent. 
[4 feet high, with a carrot-shaped root 4 inches long ; the whole plant full of а sticky white gum. Stem 
slightly four-cornered and mouldy-feeling. Leaves 4 by 8 inches. The inflated seed-vessel is elliptical, 
and 4 inches long, with a slit at its top. The root is eaten raw by the natives, who imagine it gives to 
them additional power to reproduce their species. A camp-follower ate it without feeling any effect. 
Unyoro (August).—J. A. G.] 
10. GomPHOCARPUS?,sp. In fruit only, and genus indeterminable. The stem branches 
near the base, rising to 1-1 foot ; the whole plant glabrous, except pubescent extremities. 
Leaves conduplicate when dry, rigid, oval-oblong, acute, shortly petiolate, with an obtuse 
base and undulate margin, looping lateral nerves very prominent beneath, 1-1} inch 
long. Follicles some 4 inches long, apparently from subsessile extraaxillary umbels.
