1. Dodecatheon Meadia, Linn. 



Dodecatheon Media, Linn. Spec. p. 207; Bot. Mag. t. 12, Pursh, Fl. 1, p. 136; 



Duby in DC. Prodr. 8, p. 56. 

 D. integrijolium, Michx. Fl. 1, p. 123 ; Hook. Fl. Bor.-Am. 2, p. 118 ; Duby 1. c. ; 



Benth. PL Hartw. p. 322. 

 D. frigidum, Cham, in Linnsea 1, p. 217 ; Hook. 1. c. ; Duby 1. c. 



Hab. Washington Territory and Oregon ; in prairies. — The species 

 which we have here united must all be referred to one, as our ex- 

 tensive series of specimens from very many localities abundantly 

 proves. Probably D. dentatum should be united with them. 



5. DOUGLASIA, Lindl. 



1. Douglasia nivalis, Lindl. 



Douglasia nivalis, Lindl. in Brande, Jour. Sci. 1828, p. 383, & Bot. Keg. t. 1886 ; 

 Hook. Ic. t. 180, & Fl. Bor.-Am. 2, p. 120 ; Gray in Proc. Amer. Acad. 7, 

 p. 371. 



Hab. Near Fort Okanagan on the Upper Columbia; rare in dry 

 prairies, forming large patches. — This is a very rare plant, having 

 been found hitherto only by Douglas, Richardson, and the botanists 

 of the United States Exploring Expedition. Dr. Gray has identified 

 the genus with Qregoria of Duby, and has noted that, as Douglasia 

 was published in Brande's Journal for 1827 (not 1828), this name has 

 a clear priority.
