" Notwithstanding the absence of the female flowers and the 

 fruits of this plant I am able to refer it satisfactorily to the 

 genus Corallocarpus. It is near C. cmetocathariiciis Cogn. (in 

 Bull. Soc. Bot. Belg. XXX. part i, p. 279), from which it differs 

 in its more entire leaves completely glabrous above, and its male 

 flowers being not sessile in the glomerules but very short pedi- 

 cillate."
