 ace. Merriam. 



Zone. — Arctic-alpine. 



Specimens examined. — Mt. Dana, 12,000 feet, Brewer in 1863 ; same 

 locality, 12,750-13,050 feet. Hall and Babcock 3605; Mt. Goddard,

Draiba crassifolia Graham (Edinb. New Phil. Jour., 1829, p. 182), 

 a high arctic plant found in Greenland and extending south in the 

 Rockies to Colorado, is attributed to the Sierra (Bot. Calif., vol. 1, 

 p. 28; Greene, Fl. Fran.) upon a collection made at Peregoy's 

 meadows, above the Yosemite Valley, by Dr. Gray in 1872 ; the 

 immature condition of the specimen really precludes exact determina- 

 tion whether this is D. crassifolia or an unusual state of D. stenoloha; 

 the altitude at which the collection was made (said on the label in 

 the Gray Herbarium to be 7,000 feet) suggests that it can hardly be 

 same species that is native in Greenland and alpine in the Colorado 

 mountains. 



Draha aureola Wats. (Bot. Calif., vol. 2, p. 430. 1880), described 

 from "Sierra Nevada, in Sierra County {Lemmon), and on Lassen 

 Peak, Mrs. Aiustin,^' does not appear to grow in the Sierra; Lemmon 's 

 specimen itself came from Lassen Peak, the reference to Sierra County 

 being, it would appear, an error, at least as to this collection. The
