 vii. p. 203. A robust erect herb 4-6 ft. high. Stem terete, striate, 

 glaucescent, glabrous, hollow. Leaves from a sessile hastate-lanceo- 

 late base attenuate into a long linear acute apex, glabrous, ranging up 

 to nearly a foot long ; margins with aculeate denticulations directed 

 downwards, undivided or with a few linear lateral lobes. Capitula 

 campanulate, J in. long, many-flowered, woolly at base, on mostly 

 short pedicels in an elongating cyme usually umbelliform at top. In- 

 volucral bracts linear or broader, obtuse, setose-hispid and the exposed 

 ones somewhat woolly on midrib, imbricated, in many rows, unequal. 

 Achenes compressed, smooth, J in. long, 12-15-costate ; 4 of the ribs 

 larger than the rest. Pappus f in. long, soft, white.

3. S. Schweinfarthii, 0. ^ E. Probably annual. Stem erect, 

 glabrous, striate, glaucescent, hollow, but little branched, 3 ft. high or 

 more. Stem-leaves linear-lanceolate, entire or occasionally with a few 

 large lateral lobes, sessile, semi-amplexicaul, auriculate, acute, 

 minutely denticulate, glabrous, glaucescent, ranging up to 9 by 2 in. ; 

 auriculate, auricles acute or apiculate, ranging up to § in. Capitula 

 widely campanulate, f in. long, many-flowered, on unequal rather slender 

 pedicels, in a subumbelliform cyme. Inner involucral bracts numer- 

 ous narrowly lanceolate subobtuse glabrous ; outer somewhat woolly, 

 not setose-hispid. Achenes oblong, ^ in. long, about 10-ribbed, 4 of 

 the ribs stronger than the rest, somewhat rugulose, scarcely com- 

 pressed. Pappus white, soft, f in. long. Receptacle ^ in. diameter.

 Perennial. Stem erect, somewhat shrubby at the base, branched at 

 least above, 2-4 ft. high or more, glabrous ; branches rather slender, 

 mostly divaricate. Leaves linear or nearly so and undivided (except 

 in the variety /3), usually acute, minutely denticulate, ranging up to 6 

 by I in. or more, sessile, (in the type) shortly auriculate at base ex- 

 cept the uppermost ones. Capitula |-J in. long, apparently about 

 20-fiowered, or rarely fewer, narrowly cylindrical, obsoletely tomentose 

 at the base, on short or somewhat elongated slender glabrate or pu- 

 berulous pedicels, in a lax corymbose cyme. Inner involucral bracts 

 about 8, linear or linear- oblong, obtuse, ultimately reflexed. Achenes
