Var. Jeucophyllum, GRAY, 1. c. Smaller, a span to a foot high, rather strict : leaves 

 narrow, entire or sparingly cleft or parted : heads solitary, long-peduncled : involucre cam- 

 panulate, 4 or 5 lines high, of about 8 oblong bracts : pappus in the typical plant of narrow 

 lanceolate palere, four of them twice the length of the others, but this is inconstant. Bahia 

 leucophylla, DC. 1. c. Brit. Columbia to N. California, and east to Idaho. 



Var. integrifolium, GRAY, 1. c. Low, often dwarf, cespitose-tufted, 3 to 10 inches

 summit, or at base and on sterile shoots cuneate and incisely lobed : heads rather long-pedun- 

 cled : involucre, &c., of the preceding, sometimes smaller and of only 6 bracts : palea? of the 

 pappus mostly of same length, about equalling the very glandular but not hirsute corolla- 

 tube : akeues glabrous, rarely somewhat glandular-atomiferous near the summit. 7V/-

 linear and entire (an inch or two long, half-line wide) : head on a long slender peduncle : 

 involucre nearly 4 lines high, campanulate, of about 10 oblong bracts: rays about 8: re- 

 ceptacle nearly flat, alveolate-dentate : akenes slender, 2 lines long : paletc of the pappus 

 oblong or quadrate, exceeding the breadth of the akcue. Bahia gracilis, Hook. & Arn. Bot.

 leaves cuneate or spatulate in outline, with tapering slender base or petiole, 3-lobed at sum- 

 mit : involucre 3 lines high, short-campanulate, of 6 or 7 oval bracts : rays 5 to 7 : receptacle 

 conical, naked : akenes shorter and thicker : pappus a crown of truncate laciniate-dentate

* * * Annuals, with leaves apparently all alternate, and small pedunculate heads terminating 

 the lax slender branches: receptacle conical: pappus a crown of small palea-, not lunger than 

 the breadth of the summit of the akene, sometimes very short or obsolete: style-tips conical. 



E. ambiguum, GRAY, 1. c. Somewhat loosely floccose-woolly, or denudate : stems branch-

 lanceolate (an inch or less long), entire, or 3-toothed or lobed, especially the broader 

 sometimes dilated-cuneate lowermost : involucre campanulate, 3 lines high, of 6 to 9 oblong- 

 lanceolate bracts, which are either distinct to the base or lightly coherent for two thirds their 

 length : rays 5 to 9, oblong or oval : tube of the corollas glandular-hirsute : akenes pubescent 

 or the inner ones glabrous. Lasthcnia (Monolopia) ainbiijini, Gray, Proc. Am. Acad. vi.
