12. C. pectinata, Hook. f. Handb. N.Z. Fl. 142.—Stems 1–6 in. long, creeping and rooting, rather stout, wiry, woolly or glabrate, often putting out silky runners. Leaves few, scattered, rigid, glabrous or silky, ¾–1½ in. long, linear-oblong in outline, pectinately pinnatifid; segments short, subulate, entire. Peduncles slender, naked or rarely with a minute bract about the middle, 1–3 in. long, exceeding the leaves. Heads ⅕–¼ in. diam., involucral bracts in 2–3 series, broadly oblong, pubescent, purplish; margins jagged. Female florets in several series; corolla ovoid, compressed, minutely 2–4-toothed at the narrow mouth. Disc-florets funnel-shaped, 4-toothed. Achene narrow-obovoid, compressed and slightly winged.—Kirk, Students' Fl. 325.

Var. sericea, Kirk, l.c. 326.—Smaller and more compactly branched, everywhere clothed with long dense silky hairs. Peduncles shorter and stouter, ½–1 in. long. Heads ⅓ in. diam. Perhaps a distinct species.

South Island: Nelson—Clarence Valley, T.F.C.; Mount Captain, Kirk! Canterbury—Mount Torlesse, Haast! mountains above the Broken River, Enys! Kirk! T.F.C. Otago—Lake district. Hector and Buchanan! common in mountain districts, Petrie! Var. sericea: Old Man Range and Mount Cardrona, Petrie! Ben Lomond, Cockayne! Altitudinal range from 1500 to 6000 ft. December–January.


13. C. Goyeni, Petrie in Trans. N.Z. Inst. xviii. (1886) 295.—A small tufted species. Stems 1–3 in. long, creeping and rooting, much branched; branches short, ascending at the tips, with the leaves ¼ in. diam. Leaves alternate, imbricate, appressed to the branch, ⅛–⅕ in. long; lower half broad, membranous, glabrous or more or less pubescent, sheathing at the base; upper half cut straight down into 5–7 linear-subulate erect lobes. Heads terminal, minute, ⅛ in. diam., on short woolly peduncles rarely exceeding the leaves; involucral bracts in 1 or 2 series, ovate-oblong, with scarious purple margins. Female florets few, in 1 series; corolla ovoid, compressed, narrowed at the mouth. Disc -florets numerous, funnel-shaped. Mature achenes not seen.—Kirk, Students' Fl. 326.

Var. pinnatisecta, Kirk, l.c.—Leaves pinnatifid, clothed with silky hairs.

South Island: Otago—Mount Pisa and the Hector Mountains, Petrie! 5000–6000 ft. January–February.

A curious little plant, perhaps nearest to C. pectinata. The leaves closely resemble those of Azorella Selago.


14. C. Featherstonii, F. Muell. ex Hook. f. Handb. N.Z. Fl. 733.—Stems 6–12 in. long or more, rather stout, prostrate or decumbent at the base, ascending above, much branched, leafy, clothed with short soft pubescence. Leaves alternate, ¾–2 in. long, obovate-spathulate or oblong-spathulate, gradually narrowed to a sessile base, crenately 3- or 5-toothed at the tip or entire, flat, fleshy, finely and softly pubescent on both surfaces.
