what flexuous, rough-puberulent and somewhat strigose, 

 paniculately or coryinbosely branching above: leaves nu- 

 merous, scattered, filiform an inch or two long, scabrous: 

 involucres hemispherical : rays numerous, slender, 3 — 4 lines 

 long, blue-purple: akenes usually quite glabrous. — E. 

 foliosus, var. stenophyllus, Gray, Bot. Cal. I. 330, and Syn. 

 Fl. N. A. 215. 



Common in open grounds at lower altitudes than the fol- 

 lowing species, and readily distinguishable from them by 

 the entirely different habit, the pubescence, etc. If this 

 should prove identical with the E. decumbus, Nutt, of Ore- 

 gon, the name of Dr. Gray's Texan E. stenophyllus will be 

 saved; but the Oregon plant I have not seen. The E. folio- 

 sus var. tenuissimus, Gray, is of the present species. 



E. foliosus, Nutt. 



Light green, and smoother than the preceding; stems 

 more slender, erect from the base : leaves linear to oblanceo- 

 late, obtuse, 2 — 3 lines wide, the margins scabrous: heads 

 larger, in a simple corymb: rays numerous, broader, 5 — 6 

 lines long, light purple or almost white: akenes slightly hir- 

 sute. — PL Gambel. 177. Gray, 1. c. excl. var. 



Wooded places at middle altitudes in the Sierra Nevada. 

 Of a different range from E. stenophyllus and readily recog- 

 nizable by its broader, lighter colored, smoother foliage, 

 erect stems, and simple flat-topped corymb of larger heads. 



E. inornatus, Gray. 



Near the preceding, from which it is distinguished mainly 

 by the smaller, more numerous, rayless heads, and the about 

 twice as numerous bristles of the pappus. — Syn. Fi. 215, 

 excluding the var. angustatus. 



This sjDecies belongs to the higher Sierras, whence it 

 ranges northward into Oregon and Washington. 



E. angustatus. 



Tall, rather slender and glabrous throughout : leaves nar-
