South Africa. Specimens of a South African species, in Herb. Hook., have pinnated 

 leaves, which the present species has not, and are therefore probably the true R. pin- 

 natus, Poiret.

Ledebour distinguishes* the form with tuberculated (not echinated) achenia as a 

 variety, but both states occasionally occur on the same individual. 



Species dubia vel vix nota.

The specimens in the Linnean Society's Herbarium consist of a few long-petioled 

 radical leaves, without stem or flowers, and are quite undeterminable.
