 ly collected and rather short-pednncled : 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 6-12 inches high, branching from the base, naked above : 

 leaves oblanceo'a'e 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

E. lanceolatum. Surculose-stoloniferous: stems slender, 8-12 inches 

 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 : paleae of the pappus acute, fimbriate-laciniate. In 

 marshy place?, Siskiyou Mountains near Ashland Oregon. 



E. integrifolinm Greene Fl. Fr. 444 Bahia integrifolia DC. Low, otten 

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

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

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

 ous, rarely somewhat glandular-atomiferous near the summit : paleae of the 

 pappus mootly of the same length, about equalling the very glandular 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 slener, 9-15 inches high : leaves narrowly linear and entire : heads on
