A. Cabrce, De Wild. & Durand in Comptes-rendus Soc. Bot. Belg. xxxviii. 131, 

 :f rom the Lower Congo, I have not seen. It does not appear from the description to be 

 distinct from A. sesamoides, but the authors state that A. Cabrce differs in having 

 herbaceous instead of hard and coriaceous stems and leaves, larger leaves with 

 fewer and more distant teeth, and shorter bracts.
