Dodecatheon Jeffreyi Van Houtte, Fl. des Serres 16:99. 

 1865. — It seems doubtful if there are any indigenous plants in this 

 country answering to the original description. Even the speci- 

 mens from the Californian Sierras that we have seen do not have 

 "hispidulous styles and a capsule valvate from the very apex." 

 The description was drawn from European garden plants, sup- 

 posedly grown from Californian seed, but this might easily have 

 been an error. The plant that has long passed as D. Jeffreyi 

 seems to be quite variable, and that has led to different forms of it 

 receiving specific names, so that now its name and synonomy seems 

 to be as follows: 



Dodecatheon viviparum Greene, Erythea 3:38. 1895; D. 

 tetrandum Suks. ex Greene, op. cit. 40; D. crenatum Greene, 

 Pitt. 2:74. 1890, not D. crenatum Raf.; D. dispar A. Nels. Bot.

Frasera nitjda Benth. var. Cusickii (Gray), n. comb. — F. 

 Cusickii Gray, Proc. Am. Acad. 22:310. 1887 —This is now repre- 

 sented in herbaria by a number of Cusick's collections and differs 

 from the species only in the orbicular and concave scales between 

 the filaments. These are nearly entire and surpass the ovary, as 

 is not rare in the species. Both forms occur in Oregon, the variety 

 seemingly confined to the northwestern part of the state.
