Leaves smaller than in the foregoing, and more shortly 
petiolate.

This is the well-known Cola-nut, of which the var. £. is the 
only one cultivated in the New World. 
The Sterculia cordifolia, Cav., from Senegambia, is considered 
by Brown (Pl. Jay. Rar. p. 237) to be a second species of Cola. 
In the same work, a third plant, allied to Cola, but scarcely of 
the same genus, is alluded to as gathered in Sierra Leone by 
Afzelius, and three W. African species of Courtenia are enume- 
rated: C. Afzelii, Br., from Sierra Leone and Congo ; C. triloba, 
Br., from Senegambia; and C. ? heterophylla, Br. (Sterculia hete- 
rophylla, Pal. Beauv.), from Oware.
