Leaves alternate, 1½–2½ in. long, 1 in. broad, oblong or broadly elliptic, rounded at the apex, truncate at the base, shortly petioled, coriaceous, clothed with appressed white tomentum beneath; margins undulate. Panicles spreading, exceeding the leaves. Heads $1⁄5$ in. long; involucral scales laxly imbricating; the lower farinose; the upper linear, obtuse, ciliate or pubescent. Florets 3–5.

27. O. albida, ''Hook. f. Handb. N.Z. Fl.'' 128.—A small tree 10–20 ft. high; branchlets grooved, more or less hoary with white tomentum. Leaves alternate, quite entire, 2–4 in. long, oblong or ovate-oblong, obtuse or subacute, rounded or narrowed at the base, petioiate, coriaceous, farinose above when young, glabrous when old, clothed with soft white appressed tomentum beneath; margins undulate or nearly flat. Panicles large, broad, with spreading branches; pedicels short, tomentose or farinose. Heads numerous, ¼ in. long, subcylindric; involucral scales imbricate, farinose or tomentose; the outer short, obtuse; the inner linear-oblong, often ciliate. Florets 3–6; ray-florets 1–3. Pappus-hairs unequal, thickened at the tips. Achenes linear, grooved, pubescent.—Kirk, Students Fl. 273. Eurybia albida, ''Hook. f. Fl. Nov. Zel.'' i. 118.

28. O. avicenniæfolia, ''Hook. f. Handb. N.Z. Fl.'' 127.—A small branching tree 8–20 ft. high; branchlets grooved and angular, more or less hoary with fine white tomentum. Leaves alternate, quite entire, 2–4 in. long, elliptic-lanceolate or oblong-lanceolate, subacute, narrowed into a rather long petiole, coriaceous, glabrous above, clothed with thin closely appressed white or buff tomentum beneath; veins finely reticulated, conspicuous on both surfaces; margins flat. Corymbs large, much-branched, long-peduncled, usually exceeding the leaves. Heads very numerous, small, $1⁄6$–$1⁄5$ in. long, narrow; involucre cylindric; scales few, imbricate, glabrous or minutely pubescent. Florets 2 or 3, rarely 4; ray-florets 1 or rarely 2, sometimes wanting. Pappus-hairs in one series. Achenes silky.—Kirk, Forest Fl. t. 111; Students Fl. 274. Eurybia avicenniæfolia, ''Hook. f. Fl.
