FLORA NIGRITIANA. 263 
profunde 4-sulcati, angulis obtusis. Folia 3-4 unc. longa, 
ovata, lobis basi rotundatis, utrinque fusco-viridia, opaca, 
nervis non prominülis; petiolo foliis longiore, gracili; sti- 
pulis caducis. Racemi petiolo subsequilongi, trichotome ra- 
mosi; ramis glaberrimis, gracilibus, fructiferis divaricatis. 
Bacce pauce, virides, 1 unc. longze. 
A most distinct species, though in an imperfect state. It is 
allied to an Abyssinian plant, and also to the Cape C. fragilis, 
E. Mey., but the remarkable length of the petioles and ite» 
vill at once distinguish this.

Folia integra, lanceolata, acuminata, obscure serrata, glaberrima,
