ed, the branches long, subsimple, ending in a 3~5-headed corymb. Leaves rarely 
over an inch or 14 inch long, very blunt, obscurely denticulate. 8. is much smaller 
in all parts and less fleshy ; its iny. scales scarcely ustulate. 
3. 8. littoreus (Thunb.! Cap. 681); annual, nearly glabrous; stem 
erect, fistular, with spreading branches; leaves eared and stem-clasping 
at base, oblong or oblong-hastate, or the lower ones pinnatifid, acute, 
unequally toothed or incised, the serratures deltoid, callous-tipped ; 
heads in a loose, corymbose panicle, radiate; inv. calyculate, the scales 
glabrous, oblong-acuminate, brown-tipped, membrane-edged; achenes 
striate, setulose. DC. 1. c. 379. S. arenarius, Th.! (ex pte.) p. 680. S. 
ustulatus; DC. l. c. 380. S. heterophyllus, Drege! (in Hb. Sd.) 
Var. §. hispidulus; stem and lower surface of leaves more or less rough with 
swollen, white hairs; leaves often pinnatifid, sparingly eared and sometimes tapering 
to the base. S. arenarius, Th.! (ex pte.) p. 680. (Herb. Sd., D., Cap.) 
Has. Round Capetown, in sandy ground and near cultivation; Little Namaqua- 
land and Saldanha Bay, Drege! (Herb. Th., D., Hk., Sd., Cap.) 
1-2 ft. high, loosely much branched, erect or spreading. Leaves 14-2 inches long, 
very variable, in 8. the upper leaves are often obovate, in a, usually broad based, but 
all forms occur indiscriminately together. Iny. scales brown or black-tipped, those 
of the calycle either ciliate, pilose, or quite glabrous. Drege’s “‘ 8. ustulatus” DC. is 
undistinguishable from this ; Eeklon’s (in Hb. Cap.) is S. maritimus, Linn. 
4, §. laxus (DC.? 1. c. 381); annual, quite or nearly glabrous; stem 
erect, fistular, angular, paniculately branched ; cauline leaves amply 
eared and amplexicaul at base, narrow, acute, toothed, incised or pin- 
natifid, the margin reflexed, lobes callous-denticulate ; panicle diffusely 
much branched, many-headed; pedicels slender, nude; heads (small) ; 
inv. 12-15-leaved, glabrous, calyculate; disc-fl. 20-30; rays 5-6; 
achenes oblong, minutely downy-canescent, not striate. 
Has. Olifant’s River, Drege! (Herb. Sd., D., Hk.) 
2 ft. or more high, distantly branched, weak. Lower leaves unknown; medial 1-2 
inches long, distant, the lobes 1-2 lines wide. Heads 2 lines long, the disc 14 wide. 
With the foliage of S. littoreus, this has a much more diffusely branched panicle, 
smaller fl.-heads; very narrow scales to the calyculus, and different achenes, 
5. 8. ruderalis (Harv.); annual, glabrous; stem erect, branched, rigid, 
angle-striate; leaves sessile, linear-lanceolate orlanceolate, acute, tapering 
to the base, distantly denticulate or subentire with subrevolute margins, 
sometimesslightly eared at base; heads loosely corymbose, on long, sparsely 
scaly pedicels, radiate; inv. calycled at base, glabrous, of 18-20 acute 
scales; rays 12-15, revolute; dise fl. 50-60; achenes closely puberulous. 
Has. Waste ground near Natal, 7. Williamson, J. Sanderson, 326, Gerr. & M‘K.,

1-1} ft. high, diffusely branched, the stems green. Leaves 2 inches long, 2-4 
lines wide, rather rigid when dry, on both sides green. Inv. campanulate, 2-3 lines 
long. Rays yellow, 4 lined. 
6. S. abruptus (Thunb.! Cap. 685); annual, subglabrous or sparsely 
hispidulous ; section weak, ae paniculately branched; leaves 
half-clasping at base, oblong, deeply or sharply incised or pinnatifid, 
the lobes or teeth oblong, spreading, subacute; the larger ones dentate ; 
margins reflexed; infl. laxly panicled, the pedicels elongate, scarcely
