3. Thalictrum occidentale Gray, Proc. Am. Acad., vol. 8, p. 372. 



1872. 



Type locality. — "Vancouver's Island." 



Range. — Pacific Coast from Alaska to northern California and 

 east to the mountains of Montana and New Mexico. 



Specimen examined. — Plumas Count}^, in rocky soil, Mrs. R. N. 

 Austin 166, doubtfully" referred since the foliage is thicker than that 

 of the typical form. Aside from this doubtful specimen, no other 

 evidence is at hand that this northern Meadow-rue reaches our limits, 

 except the statement by Greene (Fl. Fran., p. 310) that this species 

 is "frequent in extreme northern Calif., reaching our limits in Sierra 

 Co., at Gold Lake." 



Thalictrum alpinum L., present in the high mountain region 

 throughout the Rockies and in arctic America and Eurasia, comes to 

 the borders of our area (White Mountains, Mono County, Coville and 

 Funston 1806), but has as yet not been collected in the Sierra or in 

 the other California mountains.
