This plant is the western representative of that group of northern 

 gooseberries centering about B. oxyacanthoides (L.) Mill of the Hud- 

 son Bay region; this has as its best defined species in northeastern 

 North America R. hirtellum Michx., one form of which {R. saxosum 

 Hook.) is scarcely separable from our western plant; see Fernald.^^^ 



Rihes lacustre (Pers.) Poir, a species ranging through subarctic 

 North America and extending southward in the west as a subalpine 

 species in the Rocky Mountains to Colorado and Utah, in the Cascades 

 to the mountains of Siskiyou County, is not known from the Sierra 

 Nevada.
