South Chili, in the Cordilleras ; W. Patagonia in the steppe, especially 

 near the forest-line, but also in the mountains. This species is known to 

 me from the district of Ultima Esperanza, from Lago Argentine, where 

 it also occurs in the mountains up to about 700 m.; from Lago Viedma 

 up to about 500 m.; from the mountains between Lago Viedma and

 Fosiles up to about 850 m.; from the district of Lago Buenos Aires. I 

 do not know of it from North Patagonia. In my early papers on the 

 Patagonian Flora, this species was falsely referred to S. argenteus Kze. 

 The same mistake was probably made also by Spegazzini, both in his 

 Plant. Patag. Austral., and his Nov. Add. Flor. Patag. D.
