266 PATAGONIAN EXPEDITIONS I BOTANY. 



P. 817: 



Gnaphalium frigidum Wedd. This is not correctly named; the speci- 

 men is related to G. affine d'Urv. and is probably identical with G. nivale 

 Phil., and G. serpyllifoliiim Remy, which I believe to be only one species. 

 Call it G. serpyllifoUum Remy (Skottsb.), as described in Macl., p. 818. 

 In Cordilleras of S. Patagonia. 



Skottsberg regards G. chilense H. & A., as possibly a form of G. 

 sfackydifolium Lam. (not yet reported from Patagonia).
