Caltha.'] FLORA indica. 39 



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.

Herba annua, erecta, glabra, ramosissima, mnltiflora. Foliaradicalia 1-2-pollicaria; 

 caulina inferiora, petiolata, tripartita, segmentis angnste elongato-cuneatis 1-2-pol-

 diam. semipollicares. Petala obovata, sepalis subduplo longiora. Jchenia 5-10, 

 ^ poll, longa, oblique obovata, stylo longo rectiusciilo mucronata. 



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

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



Species dubia vel vix noia. 



1. R. vestitvs (Wall. Cat. 4707). 



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

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