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

 leaves oblanceo'aie 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 

 California. 



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

 marshy place?, Siskiyou Mountains near Ashland Oregon. 



E. integrifolium Greene PI. 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-pedun- 

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

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

 pappus mostly 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 

 long slender peduncles: involucre nearly 4 lines high, campanulate, of

62 BAHIA Lag. Nov. Gen & Spec. 30. 



SufFruticose or herbaceous plants with opposite or alternate, 

 and small or middlesized heads of yellow flowers terminating the 

 branches. Involucre hemispherical or obovate, lax or open in 

 fruit, many flowered : the plain wholly herbaceous bracts distinct, 

 in a single, or rarely double series. Receptacle small, mostly flat.
