like S. vulgaris, but the heads are erect, and are not conical by the inflexion of the 
invol. bracts after flowering. It is very near S. ramosus, but the heads are rather 
larger and ligules longer. Perhaps both these are vars. of 5. egyptius, L. 
Srcr. Il. Pseudo-jacobeea. Heads radiate, bracteolate; invol. bracts 
many-seriate, imbricate; fl. all pappose ; anther-cells not tailed.—The habit 
and involucre of the species are peculiar; the flowers are those of S. Jacobæa. 
17. S. lavandulefolius, DC. in Wight Contrib. 23; Prodr. vi. 368 ; 
woolly, stems stout woody erect densely leafy unbranched, leaves 1 in. densely 
imbricate linear-oblong from a broad subauricled base obtuse, margins strongly 
recurved entire rarely toothed or 3-fid, heads } in. diam. campanulate in dense 
or open corymbs, invol. bracts 20-40 many-seriate closely imbricate, outer 
subulate or lanceolate acuminate, ligules 10-16 short, achenes slender glabrous 
shorter than the soft white pappus. Wight. Ic. t.1133 ; Clarke Comp. Ind. 193. 
Nucuerry Mrs. ; in pastures, alt. 6-8000 ft., Wight, Ae, 
Stems from a woody stock, 6-12 in., very strict. Leaves thickly woolly, especially 
beneath, uniformly smaller upwards. Corymbs with stout erect branches and 
peduneles ; heads glabrate or woolly.—This is a very anomalous plant, on account of 
the numerous many-seriate invol. bracts, in some heads about 20, all narrowly 
lanceolate, glabrate; in others up to 40 and tomentose, the inner broadly oblong ; 
between these states there are all intermediates. One of Wight’s specimens had been 
injured by an insect, and the leaves on the lower part of its stem are flat and 
irregularly cut, or even deeply trifid with acute spreading lobes ; the uppermost are, 
however, as in all the numerous other specimens from 7 collectors, linear-oblong, 
quite entire, with strongly recurved margins, and are densely imbrieate. 
Srcr. III. Madaractis. Heads turbinate or obconie, all radiate, usually 
bracteolate ; invol. bracts l-seriate; ligules broad and long, usually 4-nerved ; 
anther-cells not tailed ; ray-fl. (all in S. belgawmensis) epappose ` pappus often 
shorter than the achenes, rigid, scabrid, often reddish, unequal, sometimes sub- 
biseriate, the outer hairs very short (pappus paleaceous below in 5. Grahami). 
(See also S. chrysanthemifolius, var. spectabilis and 5. diversifolius, both with 
epappose ray-fl.). 
* Leaves not white and cottony beneath, rarely pinnatifid. 
18. S. linifolius, Clarke Comp. Ind. 902; glabrous, stem herbaceous 
erect or ascending fastigiately leafy, leaves sessile elongate-linear subacute entire 
or distantly serrate base contracted not auricled 1-nerved, heads few bracteolate 
long-peduncled in lax corymbs, invol. bracts 15-20 à in. long linear-oblong 
acuminate, achenes slender glabrous equalling the red pappus. Doronicum

Root perennial. Stems 8-18 in., often branched from the base, very smooth, 
Leaves 3-6 by 4—4 in., green when dry, suberect and spreading, usually numerous and 
close set, having a fastigiate appearance, occasionally pinnatifidly lobed. Ligules 
10-12, elliptic-oblong, longer than the invol. bracts. Achenes $ in.; pappus not 
much longer, hairs slender, subequal, not cohering at the base. 
19. S. Gardneri, Thwaites Enum. 167 ; glabrous, stem herbaceous erect 
or ascending subsimple, leaves sessile elongate-linear distantly serrate base 
contracted not auricled 1-nerved, heads few bracteolate long peduncled in lax- 
corymbs, invol bracts 10-15 de in. long linear-oblong acuminate glabrous, 
ligules 8-10 narrow, achenes short linear pubescent equalling the whitish or 
yellowish pappus. Doronicum Gardneri, Clarke Comp. Ind, 202.
