352 glabrous. Leaves ½–1 in. long, oblong in outline, membranous, deeply pinnatifid or bipinnatifid; ultimate segments linear, entire, acute or mucronate. Heads $1⁄10$–$1⁄5$ in. diam., on long slender peduncles; involucral bracts in 2 series, linear-oblong, obtuse. Female florets numerous, in 3 series, on slender pedicels; corolla wanting. Disc-florets comparatively few, subsessile; corolla tubular, dilated at the base, 4-toothed at the tip. Achenes of the female florets obovate, with a broad thick wing, glandular on both faces; those of the disc-florets much smaller, glabrous, hardly winged.—''Handb. N.Z. Fl. 141; Fl.

3. C. atrata, ''Hook. f. Handb. N.Z. Fl.'' 142.—Rhizome stout, creeping, tortuous; roots long and stringy. Stems 1–6 in. high, erect or ascending, stout, leafy, densely pubescent. Leaves ½–1½ in. long, thick and fleshy, pubescent on both surfaces; petiole broad, flat, sheathing ar the base; blade linear-oblong or linearobovate in outline, pinnatifid; segments close-set, entire or toothed or again pinnatifid; cauline leaves smaller, pinnatifid or lobed. Heads subglobose, ⅓–¾ in. diam., black or brownish-yellow; involucral bracts in 2–4 series, linear-obovate, entire or pinnatifid, shorter than the florets or equalling them. Female florets in 3–5 series; corolla cylindric, rugose, 3–4-toothed. Disc-florets with a long rugose tube and narrow funnel-shaped 4-toothed limb. Achenes linear-oblong or linear-obovoid, rugose.—Kirk, Students' Fl. 323.

4. C. plumosa, ''Hook. f. Handb. N.Z. Fl.'' 141.—A large densely tufted aromatic species, often forming broad soft patches, everywhere clothed with long villous hairs. Stems short, stout, creeping. Leaves on long slender petioles 3–6 in. long; blade 2–6 in., oblong in outline, flaccid and membranous, finely 3–4-pinnatifid; primary divisions close-set, linear-oblong, recurved, 2-pinnatifid on the upper side; ultimate segments ⅙ in. long, linear, toothed on one side. Peduncles slender, shorter than the leaves, usually with a linear entire or pinnatifid bract about the middle. Head ⅓–½ in. diam.; involucral bracts in 2 or 3 series, broadly oblong, with broad
