C. Holtzii was described us having dioecious flowers and acuminate leaves, and I 

 theref(ire thought that the plant collected by Johnson tould not possibly be the same, 

 as it was undoubtedly monoecious, and the leaves were not at all acuminate, thus 

 differing by the latter character from all the other described African species. On 

 examining the type kindly sent on loan by Prof. Engler, however, I have come to the 

 conclusion that the male flowers have dropped off, and in addition many of tht- leaves 

 are not acuminate, just as in C. Johnsonii.
