Stenanthella occidentalis (A. Gray) Rydb. n. n. 



StcnaiUliiuni occidcntalc A. Gray, Proc. Am. Acad. 8 : 405. 



The species ranges from Alberta and British Columbia to Ore- 

 gon and Idaho. The following specimens are from the Rockies : 



Montana: Deer Lodge, 1892, J/m Emma Ware; Flathead 

 Riv^er, 1883, Canby, jj2 ; Big Blackfoot, Caiiby ; divide between 

 Hell Gate and Blackfoot, 1880, JVatson ; Columbia Falls, 1894, 

 R. S. Williams.

 E. Boitrgcau ; Kicking Horse Lake, iZZj , Jolin Macoun.

VERATRUM L. 



Flowers greenish, bractlets foliaceous, often equaling or exceeding the flowers. 



V. viride. 

 Flowers white or yellowish white ; bractlets membranous, much shorter than the pedi- 

 cels and flowers. V. speciosum. 



Veratrum viride Ait. Hort. Kew. 3: 422. 1789 



V. lobeliamim /9 EsclischoltziaiiiDJi R. & S. Syst. 7 : 1555. 1 829. 



V. Eschscholtcii Grsiy, Ann. Lye. X. 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 of V. viride or J^. Eschscholtziaintm, 

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

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

 Rockies.
