2. S. angustissimus, Hook. f. in Journ. Linn. Soc. Lond. Bot. 
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, 3 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, } in. long, 12-15-costate ; 4 of the ribs 
larger than the rest. Pappus 3 in. long, soft, white.

3. S. Schweinfurthii, 0. § H. 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 3 in. Capitula 
widely campanulate, 2 in. long, many-flowered, on unequal rather slender 
pedicels, in a subumbelliform cyme. Inner involucral bracts numet- 
ous narrowly lanceolate subobtuse glabrous; outer somewhat woolly H 
not setose-hispid. Achenes oblong, } in. long, about 10-ribbed, 4 © 
the ribs stronger than the rest, somewhat rugulose, scarcely com- 
pressed. Pappus white, soft, 2 in. long. Receptacle 4 in. diameter.

Perennial. Stem erect, somewhat shrubby at the base, branched 4 
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 
by in. or more, sessile, (in the type) shortly auriculate at base ex 
cept the uppermost ones. Capitula g-1 in. long, apparently about 
20-flowered, or rarely fewer, narrowly cylindrical, obsoletely tomentose 
at the base, on short or somewhat elongated slender glabrate or pt 
berulous pedicels, in a lax corymbose cyme. Inner involucral bracts 
about 8, linear or linear-oblong, obtuse, ultimately reflexed. Achenes 
yo.in. long, about 10-striate, rough. Pappus 4 in. long.—S. laces
