2. L. petiolata, Hook. f. Fl. Nov. Zel. i. 125.—Habit of L. Forsteri, but smaller and much more slender. Leaves usually radical, spreading, ½–1½ in. long; petiole slender, half the length or more; blade variable in shape, obovate to orbicular, sometimes broader than long, obtuse, rather thin, acutely coarsely toothed with the teeth apiculate, more or less hairy on looth surfaces, often purplish beneath. Scape very slender, strict, 2–6 in. long, usually hirsute. Heads small, 15–13 in. diam.; involucral bracts linear, acute, often purplish at the tips; margins scarious. Ray-florets numerous; ligule very narrow, revolute. Achenes rather longer and more turgid than in L. Forsteri, linear-obovate, curved or falcate, slightly glandular above, narrowed into a rather long beak; margins thickened.—Handb. N.Z. Fl. 137; Kirk, Students' Fl. 257. L. strangulata, Col. in Trans. N.Z. Inst. xxii. (1890) 471.
Var. minima, Cheesem.—Very small, ½–2 in. high. Leaves with the petiole ½–1 in. long, membranous, dentate, sometimes lobed or pinnate at the base. Scapes filiform. Heads small.—L. Forsteri var. minima, Kirk, l.c.
North and South Islands, Stewart Island: Not uncommon from the Upper Thames and Waikato southwards, ascending to 4000 ft. November–January. Var. minima: Moist rocks by the side of streams; Bay of Islands to Te Aroha.
Very closely allied to L. Forsteri, but separated by the more slender habit, smaller and thinner leaves, smaller heads with shorter and narrower rays, and longer and narrower curved achenes. Mr. Kirk places the var. minima under L. Forsteri, but to me it appears much nearer to L. petiolata.
3. L. Barkeri, Kirk, Students' Fl. 257.—Stems leafy, slender, erect, 3–9 in. high. Leaves cauline, usually gradually diminishing in size upwards, 1–2 in. long; petiole about half the length; blade obovate-spathulate to narrow oblong-spathulate, obtuse or subacute, gradually narrowed into the petiole, coarsely crenate-dentate, scaberulous on both surfaces. Scape shorter or longer than the leafy part of the stem, scaberulous and pilose. Head ⅓–½ in. diam.; involucral bracts linear, acute, thin, often purplish. Ray-florets numerous; ligules white, revolute. Ripe achenes not seen.
South Island: Nelson—Sphagnum swamps in the Clarence Valley and near Lake Tennyson, T. F. C. Canterbury—By the Porter River, Kirk! Craigieburn Mountains, Cockayne! Cass River, near Lake Tekapo, T. F. C. 1500–3500 ft. December–January.
Far too closely allied to L. Forsteri, from which it only differs in the leafy stems, narrower scaberulous leaves, and (according to Kirk) in the linear short-beaked achenes.
4. L. purpurea, Kirk, Students' Fl. 257.—"Stems leafy below, naked above, erect, slender, grooved, 4–6 in. high, pubescent or puberulous. Leaves (including the petiole) 1½ in. long, membranous, ovate, radical and cauline, rather distant, truncate at the base, rounded at the apex, serrate or crenate-serrate, teeth apiculate, pubescent on both surfaces, ciliate, purple beneath. Heads ⅓–½ in.
