Olearia.] Differs from O. furfuracea in the much smaller size, smaller close-set excessively rigid and coriaceous leaves, and especially in the much larger heads with twice the number of florets. I have a plant from Castle Hill, Coromandel, which resembles it in foliage, but forms a large shrub 12 ft. high. A similar form has been gathered by Petrie at Mercury Bay. But both of these have few-flowered heads only slightly larger than those of the typical state of O. furfuracea, and are best placed under that species.

13. O. nitida, ''Hook. f. Handb. N.Z. Fl.'' 125.—A much-branched shrub 3–12 ft. high, rarely more; branches stout or slender, often angular. Leaves alternate, variable in size, 1½–3½ in. long, broadly ovate or elliptic-ovate, acute or acuminate, rounded and often unequal at the base, coriaceous or almost membranous, clothed with appressed white and satiny tomentum beneath; margins distinctly or obscurely sinuate-dentate, rarely entire; petiole ½–1 in. long. Corymbs large, rounded, much-branched, very effuse; branches slender, silky-pubescent. Heads numerous, $1⁄6$–$1⁄4$ in. long, obconic; scales of the involucre laxly imbricating; the outer ovate, pubescent or villous; the inner linear, fimbriate or sparingly silky. Florets 15–20; ray-florets 7–10, with a short broad ray. Pappus-hairs unequal, dirty-white or reddish. Achenes short, broad, silky.—Kirk, Students' Fl. 268. O. populifolia, ''Col. in Trans. N.Z.
