½–1 in. diam., yellow; involucral bracts glandular and tomentose. Rays ¼–½ in. long, spreading. Achenes linear, glabrous.—Choix, 21, t. 17; Hook. f. Fl. Nov. Zel. i. 143; Handb. N.Z. Fl. 158; Kirk, Students' Fl. 338.

North and South Islands: Not uncommon from Taupo and the Ruahine Mountains to the south of Canterbury. Sea-level to 4500 ft. November–January.


2. S. bellidioides, Hook. f. Fl. Nov. Zel. i. 144.—Very similar to S. lagopus, but smaller and more slender. Leaves all radical, spreading; blade ¾–4 in. long, broadly oblong to linear-oblong, obtuse or subacute, rounded or slightly cordate at the base or narrowed into the petiole, membranous or subcoriaceous, entire or crenulate, upper surface rugose or almost flat, more or less covered with short stiff bristles, beneath glabrate or sparingly clothed with white or brownish tomentum; petioles long or short, usually woolly. Scapes 1–12 in. high, simple or branched, cottony or glandular-pubescent, rarely glabrate; bracts few, small, acute. Heads 1 to many, ½–1 in. diam.; involucral bracts tomentose or glabrate. Achenes linear, glabrous.—Handb. N.Z. Fl. 159; Kirk, Students' Fl. 338. S. Traversii, F. Muell. in Trans. Bot. Soc. Edinb. vii. (1861) 154.

Var. glabratus, Kirk, l.c.—Leaves broadly oblong, glabrous beneath, sparingly setose above.

Var. angustatus, Kirk, l.c.—Leaves linear-oblong, apex rounded or subacute.

South Island, Stewart Island: Not uncommon in mountain districts throughout. 2000–5000 ft. December–February.

This appears to pass into S. lagopus, but in its usual state can generally be distinguished by the smaller size and more membranous leaves, which are often quite glabrous beneath, seldom white and cottony.


3. S. Haastii, Hook. f. Handb. N.Z. Fl. 159.—Rootstock stout or slender, more or less clothed at the top with soft whitish wool. Leaves all radical; blade 2–5 in. long, broadly oblong or orbicular-oblong, obtuse at the tip, rounded or slightly cordate at the base, subcoriaceous, obscurely crenulate, both surfaces covered with soft white lax or appressed tomentum, or the upper surface hoary-tomentose or almost glabrate; petioles slender, 2–6 in. long, white and cottony. Scapes slender, 5–15 in. high, simple or branched, cottony and slightly glandular; pedicels long, slender; bracts few, linear or linear-obovate. Heads 1–8, ¾–1½ in. diam.; involucral bracts linear-oblong, subacute, white and cottony. Achenes narrow-linear, glabrous.—Kirk, Students' Fl. 339.

South Island: Nelson—Clarence Valley, T.F.C. Canterbury—Broken Eiver, Enys! Kirk! T.F.C.; Mount Cook district, Haast! T.F.C.; shores of Lake Ohau and source of the Ahuriri, Haast. Otago—Lake Hawea, Haast; not uncommon in the interior, Hector and Buchanan! Petrie! 1500–4000 ft. December–January.
