 Pirius Nuttallii, Parlatore in De CandoUe Prod. XVI^, 412. 



Abundant and large in the Kootanie-Colurabia valley, and in the 

 lower parts of smaller valleys tributary to it, ending to the north with 

 Pinus ponderosa at the head of the upper Columbia Lake. Probably 

 wanting in the Selkirk and Gold ranges, save in excejitionally low 

 valleys. To the west of these ranges, sparingly, about Great Shu- 

 swap Lake; also, in the Coldstream valley, near the head of Okinagan 

 Lake. The summit between Osoyoos Lake and the Kettle Eiver was 

 named Larch-tree Hill by the boundary commission expedition, this 



being the first place at which the tree was found abundantly in travel-
