116 COL. GRANT—BOTANY OF THE SPEKE AND GRANT EXPEDITION. 
9. ІРОМЖА INVOLUCRATA, P. de Beauv.; DC. Prod. ix. 365; App. Speke's Јошт. 640. 
Hab. Unyoro, Nov. 1862, Col. Grant! Widely diffused in Tropical Africa. 
[A climber. Equator and 2? N. lat.—J. А. 6.1 
10. IPoMJEA PTERYGOCAULOS, Choisy, in DC. Prod. ix. 881, App. Speke's Journ. 640. 
Hab. Banks of Nile, north of Gondokoro, Col. Grant ! 
In Col. Grant’s specimen (which does not show the corolla) the leaves are all deeply 5-lobed ; but so 
they become on the same shoot with the 3-lobed leaves in the type specimens of Schimper. 
11. ТРОМЖА COMMATOPHYLLA, A. Rich. FI. Abyss. ii. 65.—Convolvulus commato- 
phyllus, Steud. in hb. Schimp. Abyss. 783; App. Speke’s Journ. 640. Var. angustifolia ? 
Col. Grant’s plant differs from the type in its much narrower leaves, with a narrow lateral lobe on each 
side ; but otherwise I think it may be conspecific. The seeds are more or less hairy, not glabrous, as are 
described the seeds of 7, Kotschyana, Hochst. (DC. Prod. ix. 354). 
Hab. X N. lat., Col. Grant !
