This should probably be deleted ; its occurrence in South Patagonia is 

 very doubtful ; and Macloskie's statement of its occurrence in Chili is also 

 scarcely correct. D.

 mined by O. Kuntze as B. genistifolia represent, according to F. Kurtz,

 agonia, Mid-Patagonia, South Patagonia, from the east coast to the pre-
