The aflSnitj of this genus appears to be with Fisosperma, Sonder, 

 which is also South African, and from which it differs in the structure 

 of the anthers, in the stigmas, in the 2-fid tendrils and form of the 

 fruit. Though I have seen several sheets of the plant, none show 

 whether it is monoecious or dioecious. The separation of the cells of 

 the two-celled anthers is complete, bisecting the connective and very 

 short filaments, each cell resembling a free l-celled anther. — J. D.
