Type locality. ' ' On a peak of the Sierra Nevada south of Sonora 

 Pass, alt. 11,500 feet." 



Range. Central and southern Sierra Nevada; central Idaho. 



Zone. Arctic-alpine. 



Specimens examined. Peak near Sonora Pass, 11,500 feet, Brewer 

 1909 ; Old Mt. Whitney, 13-14,000 feet, Purpus, August, 1896. 



Reported by Miss Eastwood 89 to form mats above timber line, Har-

6. Draba Breweri Wats., Proc. Am. Acad., vol. 23, p. 260. 1888. 



Type locality. "On Mt. Dana, at 12,000 feet altitude." 



Range. Central and southern Sierra Nevada. Also on Mt. Shasta, 

 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, 

 13,500 feet, Hall and Chandler 669 ; mountains near Little Kern River, 

 rocky slopes at 11-12,000 feet, Purpus 5658. 



Miss Eastwood 89 found this species in the high mountains of Tulare 

 County, in Kearsarge and Harrison's passes. Merriam reports this 

 species growing on Mt. Shasta at 13,000 feet. 53 



Draba 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. stenoloba; 

 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. 



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

 from "Sierra Nevada, in Sierra County (Lenimon), and on Lassen 

 Peak, Mrs. Austin," 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
