tapering into petioles, the upper usually alternate : akenes 

 obovate-oblong, not cuneate at base, glabrous except the 

 ciliolate margins of the imperfect wings, less obcorclate than 

 in the preceding species; pappus of two short, firmly per- 

 sistent awns, and numerous intermediate, equally persistent 

 squamellte ; terminal areola depressed. — H. California, 

 Gray, of Bot. Cal. and Syn. Fl. as to the plant of the Sierra 

 only. 



Abundant in the higher Sierra, often collected, and by no 

 means to be disposed of as a pappose form of the true H. 

 Calif arnica. The akenes differ in size aud shape, as well as 

 in the wholly constant matter of the pappus.

Annual; stem slender, a foot and a half high, above the 

 middle abruptly parting into a loose, corymbose panicle: 

 leaves linear, entire : peduncles slender, 2 — 4 inches long : 

 ray-flowers about 10, a half inch long, bright yellow; those 

 of the disk 18 — 30 : bracts of the involucre minutely hispid : 

 ray-akenes slightly lunate, the rather prominent and quite 

 lateral apiculation bearing a short ciliolate pappus; pappus 

 of disk-flowers of 5 slender and soft, barbellate awns. — 31. 

 Yosemitana, Gray, Syn. Fl. 304, as to the plants of Prof. 

 Eisen and Marcus Jones, but not of Parry. 



The present species is abundant in the region of the 

 Sierra Nevada from Auburn northward at least to the Yuba 

 River, and has been collected in imperfect condition by Mr. 

 Elisha Brooks, as well as by the gentlemen above named. 

 This description has been drawn from beautiful and very 

 perfect specimens collected at Nevada City, last July, by 

 Mr. Charles A. Kamm, for whom it is named. As to the 

 pappus of both ray and disk, the species is very close to M. 

 Yosemitana; but the ray-akenes are more crescent-shaped 

 and have their terminal apiculation and basal stipe both 

 more lateral. In size and habit, as well as geographical
