t. 896. 
Hab, Karagué and Unyoro, Col. Grant! Cultivated throughout the tropies. 
[Native name “ gueenguezo ” and “ maharageh.” Surface of the plant purple and glossy, and covered 
with.fine down. Corolla mauve-coloured. Seeds scarlet. А variety had pure white flowers, and grew 
like a bush. Its leaves are dried and eaten as a vegetable. Тһе beans are also eaten, but not considered 
good, as they induce flatulenoy.—J. A. G.]

Afr. ii. 213. 
Hab. Usui, November 1861, Col. Grant! Grows also in Abyssinia and Sennaar. 
57. DorrcHos? sp.— Pachyrhizus sp.? of App. Speke's Journ. 631: cited under 
P. angulatus, Rich., by Mr. Baker in FI. Trop. Afr. ii. 208; identical also, I think, with 
Tephrosia sericea, Baker, 1. с. 107. ! 
_ Hab. Woods, Madi, J anuary 1863, Col. Grant ! 
A remarkable plant, with virgate branches, attaining 4 ft. in height. The flowers are precocious, as in 
some curious species of Dolichos collected in Lower Guinea by Dr. Welwitsch ; the leaves trifoliolate 
and stipellate. The stigma is penicillate, and not lateral and globose as in Pachyrhizus. 
[When collected, in the woods of Madi, in J anuary, it was in flower, but had no root-leaves.—J. A. G.] 
58. CAJANUS INDICUS, Spreng. Syst. Veg. iii. 248; Baker, in Fl. Trop. Afr. ii. 216. 
_ Hab. Unyoro, July 1862. * Met with and cultivated everywhere," Col. Grant! Cul- 
tivated throughout the tropics. :

as turning stick, to strike a light—J. A. G.J :

Hab. Karagué, Dec. 1861, and Unyoro, November 1862, Col. Grant! Also in Tro- 
pical Asia. 
The Karagué and Unyoro specimens differ in habit and relative length of calyx and 
corolla; but I am not sure of any specific difference between them.
