More herbaceous than 8. rigidus, with (usually) more deeply-cut or pinnatifid 
leaves, but very variable. Var. 8. (Hb. Sd.) looks like a weak state of S. rigidus ; 
y. is unknown to me ; 5. (Herb. Sd., Hk.) ought perhaps to be made the type of the 
species. Leaves 2-6 inches long, 1-14 wide. Heads not 2 lines long, campanulate. 
is is unquestionably the S. /yratus, Th., and therefore probably of Linn. f., but 
not of De Candolle. The specimens examined by me are not sufficiently copious to 
enable me to judge of its specific limits, or whether all the varieties might not be 
referred to 8. rigidus. 
100. S. rigidus (Linn. Sp. 1224); a large shrub ; branches striate, 
terete, roughly hispid, the upper ones herbaceous, panicled at summit ; 
leaves stem-clasping and often adnate-subdecurrent at base, oblong, or 
fiddle-shaped, obtuse or acute, the smaller often obovate, sharply and 
unequally toothed, scabrous above, more or less cobwebbed, and netted- 
veined beneath, harsh to the touch; corymb much branched, its divi- 
sions closely many-headed, pedicels scaly ; heads radiate, 20-30-fl. ; rays 
5-6, yellow; inv. calycled, glabrous, of many narrow scales; achenes 
striate, hispidulous. Zh./ Cap. 682. DC. 1. c. 392. 
Var. 8. scaber; rameal leaves conspicuously adnate-decurrent at base, obovate- 
oblong, obtuse, green on both sides, not cobwebbed. S. scaber, Willd., DC. Ll. c. 334.

8-12 ft. high, much branched, scabrous and rough to the touch in most parts. 
Leaves 2-3 inches long, 1-2 in. wide, variable in shape and pubescence, sometimes 
almost woolly beneath. Infl. very compound, the heads small; inv. 14-2 lines long. 
101. §, caulopterus (DC.! 1. c. 388); stem herbaceous, erect, rib-stri- 
ate, minutely pubescent ; branches corymbiferous; cauline leaves obo- 
vate or oblong, sharply calloso-denticulate, glabrous ot cobwebbed above, 
minutely hispidulous, penninerved and closely reticulate beneath, decur- 
rent at base into a long, toothed or subentire stem-wing ; upper lvs. 
ovate, sub-sessile; corymb compound, laxly many-headed, the pedicels 
long, somewhat scaly; inv. calycled, of 9-12 glabrate scales; disc-fi. 
10-12, rays 4-5; achenes (young) ‘hispidulous.

Of Drege’s! plant I have seen but the apex of a branch and one of the uppermost, 
non-decurrent leaves ; my description therefore is chiefly adapted from DC. 1. c.
