FLORA NIGRITIANA. 
I. RANUNCULACEZ, 
1. Clematis grandiflora, DC. Syst. Veg. 1. p. 151.—C. chlo- 
rantha, Lindl. Bot. Reg. t. 1234.—Sierra Leone, Don. 
The west coast of Africa offers a striking instance of the 
Scarcity of Ranunculacee in all hot, damp and low climates ; 
for there it is represented by a solitary genus, and of this genus 
One other species only is known as an inhabitant, the C. hirsuta, 
Guill. and Perr., from the Cape de Verd. It is probable that, 
as in Tropical Asia, the genus affects hilly localities, for no 
Species occur in any of the collections made on the flat and 
"mid coasts south of Sierra Leone.
