Olearia.] 8. O. Lyallii, Hook. f. Fl. Nov. Zel. i. 116.—A robust shrub or small tree, sometimes reaching the height of 30 ft., with a trunk 18–24 in. diam.; branches stout, spreading, densely tomentose. Leaves 4–8 in. long (or more in young plants), ellipticovate or orbicular-ovate, abruptly acuminate, shortly petiolate, excessively rigid and coriaceous, white with floccose tomentum above but becoming glabrous when old, under-surface densely clothed with soft white wool; margins irregularly doubly crenate. Racemes terminal, stout, 4–8 in. long; rhachis, pedicels, and bracts clothed with snow-white wool. Heads large, discoid, 1¼–1½ in. diam., darkbrown; involucral scales numerous, in 4–8 series, linear, villous at the tips. Achenes densely silky.—''Handb. N.Z. Fl. 125; Kirk, Students' Fl.'' 266. Eurybia Lyallii, ''Hook. f. Fl. Antarct.'' ii. 543.

9. O. Buchanani, T. Kirk, Students' Fl. 267.—An erect shrub or small tree; branchlets as thick as a goose-quill, reddish, glabrous. Leaves opposite, 2–4 in. long, elliptic-lanceolate, obtuse, gradually narrowed into a short petiole, quite entire, flat, glabrous above, clothed with thin appressed whitish tomentum beneath; veins finely reticulated above, obscure beneath. Heads small, ¼ in. long, in rather loose branched axillary corymbs about equalling the leaves; pedicels slender, pubescent. Involucral scales 8–10, pubescent at the tips. Florets of the ray 3–4, ligulate; of the disc about 4, campanulate above. Achenes short, grooved, pubescent.

10. O. Traversii, ''Hook. f. Handb. N.Z. Fl.'' 731.—A small tree 15–30 ft. high, with a trunk 1–2 ft. diam.; bark pale, furrowed; branches tetragonous, clothed with appressed silky tomentum, as are the leaves beneath, branches of the inflorescence, and involucres. Leaves opposite, 1½–2½ in. long, oblong or ovate-oblong to broadly ovate, acute or apiculate, shortly petiolate, quite entire, flat, glabrous above or slightly silky when young. Panicles numerous, axillary, much-branched, shorter or longer than the leaves. Heads numerous, small, ¼ in. long, discoid; scales of the involucre few, linear-oblong, obtuse or subacute. Florets 5–15; outer ones female, with a minute tubular corolla with an oblique mouth; central hermaphrodite, campanulate above; style-branches
