Lagenophora. | COMPOSITZ. 273 
2. L. petiolata, Hook. f. Fl. Nov. Zel. i. 125.—Habit of 
L. Forsteri, but smaller and much more slender. Leaves usually 
radical, spreading, 4-14 in. long; petiole slender, hali 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 both surfaces, often 
purplish beneath. Scape very slender, strict, 2-6in. long, usually 
hirsute. Heads small, $-4in. 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 ZL. Forsteri, limear-obovate, curved or falcate, 
slightly glandular above, narrowed into a rather long beak ; margins 
thickened. — Handb. N.Z. Fl. 187; Kirk, Students’ Fi. 257. 
L. strangulata, Col. in Trans. N.Z. Inst. xxii. (1890) 471. 
Var. minima, Cheesem.—Very small, $-2in. high. Leaves with the petiole 
4-lin. long, membranous, dentate, sometimes lobed or pinnate at the base. 
Scapes filiform. Heads small.—L. Forsteri var. minima, Kiri, l.c. 
NortH AnD SoutH IsLANps, 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 LZ. 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 
ZL. Forsteri, but to me it appears much nearer to L. petiolata. 
3. L. Barkeri, Kirk, Students’ Fl. 257.—Stems leafy, slender, 
erect, 8-9in. high. Leaves cauline, usually gradually diminishing 
in size upwards, 1-2in. long; petiole about half the length ; blade 
obovate-spathulate to narrow oblong-spathulate, obtuse or sub- 
acute, 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 4-1in. diam. ; 
involucral bracts linear, acute, thin, often purplish. Ray-florets 
numerous; ligules white, revolute. Ripe achenes not seen. 
SoutH Istanp: Nelson—Sphagnum swamps in the Clarence Valley and near 
Lake Tennyson, 7. #’. C. Canterbury—-By the .Porter River, Kirk! Craigie- 
burn Mountains, Cockayne! Cass River, near Lake Tekapo, 7. F’. C. 1500- 
3500 ft. December—January. 
Far too closely allied to L. Forster, 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—6in. high, pubescent or 
puberulous. Leaves (including the petiole) 14in. long, membran- 
ous, 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 4-1 in.
