at the base. E. B. t. 748. — /3. leaves distinctly auricled and 
amplexicaul at the base. S. lividus L. ? : E. B. t. 2515. 
Dry upland soils, banks, and gravelly pastures. Q. 7 — 9 
Stem 14 — 2 ft. high. Plant with a disagreeable smell, but not so 
powerful as that of S', viscosus. The S. lividus of Linn, is a Spanish 
species, and unknown to us ; but whatever it be, we fear the plant 
of E. Bot. cannot be considered specitically distinct from the present. 
** Heads with a spreading ray. Involucre with small scales at the base. 
Leaves pinnatijid. 
4. S. * squdlidus L. (inelegant R.) ; ray spreading its ligules 
elliptical entire, leaves glabrous pinnatifid, with distant oblong 
and toothed segments, involucre glabrous, its outer scales few 
small, achenes silky. E. B. t. 600. 
On walls in and about Oxford. Walls and rubbish at Bideford, 
Devon. 0. 6 — 10. — A most distinct species, but scarcely indige- 
nous. 
5. S. tenuifdlius Jacq. (hoary if.) ; ray spreading its ligules 
oblong, leaves closely pinnatifid pale and downy beneath, seg- 
ments linear their margins somewhat revolute, stem erect 
loosely cottony, outer scales half as long as the inner, all the 
achenes silky. E.B.t.SlA. S. erucasfolius L.? 
Hedges and road-sides in England, especially in a chalky or gra- 
velly soil. Woodhall, near Airdrie; Berwickshire, in various places. 
74. 7, 8. — Allied to the following, but with more regular, less 
divided, and less spreading segments to the leaves. Rhizome creeping. 
6. S. Jacobce'a L. (common if.) ; ray spreading, leaves lyrate 
bipinnatifid, segments divaricated toothed glabrous, stem erect, 
achenes of the disk hairy, those of the ray glabrous, involucre 
hemispherical. E. B. t. 1130. 
Way-sides and neglected pastures, too plentiful. If.. 7 — 9. — 
Stems 2 — 3 feet high, striate, branched. Heads of flowers large, 
golden-yellow, in erect corymbs. A var. is occasionally found without 
the ray. 
7. S. aqudticus Huds. (Marsh R.); ray spreading, leaves 
lyrate serrate glabrous the lowermost obovate and undivided, 
involucre hemispherical, achenes all glabrous. E. B. t. 1131. 
Wet places and by the sides of rivers and ditches. 2/.. 7, 8 . 
Heads of flowers larger than in the last species. 
*** Heads with a spreading ray. Involucre with small scales at the 
base. Leaves undivided. 
8. S . paludusus L. (great Fen if.); ray spreading its ligules 
toothed, leaves semiamplexicaul lanceolate sharply serrate
