V. Eschscholtzii Gray ■, Ann. Lye. N. Y. 4 : 119. 1837. 



If the western plant should be included in V. viride or not, is 

 doubtful. The eastern plant extends west to Minnesota and the 

 western is found first on the Pacific slope in Idaho and British Co- 

 lumbia. Both are very variable and no good character has been 

 found to separate the two. As a rule the western plant has shorter 

 stamens and bracts ; the former scarcely half as long as the petals 

 and sepals. The western range o( V. viride or V. Eschscholtzianum, 

 whatever name it should bear, is from southern Alaska to Oregon 

 and Idaho. The following are the only specimens seen from the 



Rockies.
