Lagenophora.] 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, $1⁄5$–$1⁄3$ 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.

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.
