138 PATAGONIAN EXPEDITIONS : BOTANY. 



6. CARDAMINE INTEGRIFOLIA Phil. 



Syn. C. rostrata Gris var. dichondroides Speg. (Described Macl., p. 438, 



No. 13, as rostrata dichondroides]. 



W. Patagonia in subandine and andine district by Rio Chubut, and

Note. C. pratensis L. is stated by A. B. Rendle to occur in S. Pata- 

 gonia, by Lago Argentine (Journal of Botany, Vol. 42, 1901, p. 328). 

 According to O. E. Schulz it does not occur in S. America. Possibly 

 Rendle's determination may refer to C. vulgaris Phil., which, according 

 to Gilg & Muschler in Engler's Bot. Jahrb., Bd. 42, p. 462, replaces C. 

 Pratensis in Chili.
