COMPOSITÆ.
[Pleurophyllum.

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. Albinea orisegenesa, Homb. & Jacq. Voy. Astrol. et Zèl. 37, t. 4.

Auckland and Campbell Islands, Antipodes Island: Abundant from sea-level to over 1000 ft. December–January.

Separated from the preceding by the petiolate leaves and subglobose discoid heads. Kirk has pointed out that the plate in the "Flora Antarctica," excellent in most respects, is faulty in the leaf figured not being that of the present species, but of P. speciosum.


3. P. Hookeri, Buch. in Trans. N.Z. Inst. xvi. (1884) 395 (excl. t. 37).—Leaves all radical, 6–12 in. long, 3–4 in. broad, obovate or oblong-obovate, acute or acuminate, narrowed into a short broad petiole, coriaceous, clothed on both surfaces with rather loose white and silvery tomentum; principal nerves 8–12, slender; margins entire or minutely denticulate. 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. Pappus-hairs hardly thickened above.—Kirk, Students' Fl. 278. P. Hookerianum, Kirk in Trans. N.Z. Inst. xxiii. (1891) 435. P. Gilliesianum, Kirk in Rep. Austral. Assoc. (1891) 220.

Auckland Islands: Kirk! Campbell Island: Buchanan! Kirk! Macquarie Island: Scott, Hamilton! 500–1000 ft. December–January.

Closely allied to the preceding, but sufficiently distinct in the smaller size, leaves silvery-tomentose on both surfaces, rigid scapes, and smaller heads.


6. CELMISIA, Cass.

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;
