296 beneath, above setose with moniliform hairs intermixed; principal nerves 8–16, parallel, but following the outline of the leaf; margins remotely and minutely spinulose-serrate. Cauline-leaves smaller and narrower, sessile, clothed with thin white tomentum on both surfaces. Flowering-stem stout, 2–6 ft. high; raceme of 15–30 heads or more. Heads subglobose, discoid, 1–1½ in. diam., purple; involucral bracts ovate-lanceolate, margins ciliate. Ray-florets with a very short and inconspicuous 2–3-fid ligule. Achenes silky-strigose. Pappus-hairs slightly thickened at the tips.—''Handb. N.Z. Fl. 129; Kirk in Trans. N.Z. Inst.'' xxiii. (1891) 434. P. Hombronii, ''Dcne, in Voy. Astrol. et Zèl.'' 36.

Flowering-stems 1–3, 1½–2 ft. high, strict, silky-tomentose, naked below excepting for 1–3 narrow-linear bracts; raceme of 12–24 heads. Heads subglobose, discoid, ¾ in. diam.; involucral bracts narrow-linear, acuminate. Ray-florets few, with a very short and inconspicuous 2-lobed ligule. Achene silky.

Perennial herbs, usually tufted or with a short creeping rhizome, rarely with a procumbent or suberect branched stem. Leaves all radical and rosulate, or cauline and densely imbricated, narrowed into a sheathing base, usually clothed beneath with appressed white or buff tomentum. Scapes or peduncles long or short, rarely almost wanting, bracteate. Heads large, solitary, radiate. Involucre broadly hemispherical; bracts imbricated in several or many series, narrow, pubescent or cottony or glandular. Receptacle flat or convex, pitted. Ray-florets female, in a single row, ligulate;
