 ucral bracts 8-13, oblong or oval, often more or less united; rays 

 6-12, 6-8 lines long; tube of the disk-corollas mostly hirsute-glandular

 corymbosely collected and rather short-peduncled : involucre hemispherical, 

 3-4 lines high, of 9-13 narrow bracts: rays 9-13, 6-8 lines long, usually 

 narrow : achenes sparsely pubescent or glabrate. Southern Oregon to 

 California. 



E. leucophyllum Bahia leucophyllum DC. Lanuginose-tomentose 

 throughout : stems 6-13 inches high, branching from the base, naked above : 

 leaves oblanceolate or oblong-spatulate, 3-cleft or lobed at the apex, or 

 somewhat pinnately incised or the upper linear and entire: heads solitary, 

 long-peduncled ; involucre campanulate, 4-5 lines high, of about 8 oblong 

 bracts ; rays oblong : achenes glabrous : pappus of 4 oblong or lanceolate 

 acutish scales and as many alternate smaller ones. Dry plains, Alaska to

 high, simple, bearing a single large head or few-flowered cyme, floccose- 

 woolly: leaves lanceolate and entire, or the lower ones spatulate and spar- 

 ingly dentate toward the apex, 6-12 lines long, densely white-tomentose 

 when young: involucre 5-6 lines high, very densely white-tomentose, of 

 10-15 lanceolate bracts : palese of the pappus acute, fimbriate-laciniate. In 

 marshy places, Siskiyou Mountains near Ashland, Oregon. 



E. integrifolium Greene -Fl. Fr. 444 Bahia integrifolia DC. Low, often 

 dwarf, cespitose, 3-10 inches high: leaves from narrowly spatulate and en- 

 tire to more dilated and 3-lobed, floccosely hoary; heads rather long 

 peduncled; involucre cylindrical, of 6-8 narrowly oblong bracts: achenes 

 glabrous, rarely somewhat glandular-atomiferous near the summit: palese 

 of the pappus mostly of the same length, about equalling the very glan- 

 dular but not hirsute corolla^tube. Brit. Columbia to California and the 

 Rocky Mountains : usually only on the highest mountains. 



E. gracile Gray Proc. Am. Acad, xix, 25. Loosely floccose- woolly ; 

 stems slender, 9-15 inches high; leaves narrowly linear and entire; heads
