26. O. angulata, T. Kirk in Trans. N.Z. Inst. xiii. (1881) 384.—A much-branched shrub 8–12 ft. high; branches short, spreading, grooved, ahiiost hoary. 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 15 in. long; involucral scales laxly imbricating; the lower farinose; the upper linear, obtuse, ciliate or pubescent. Florets 3–5. Pappus-hairs unequal. Achenes strigose.—Students' Fl. 273.
North Island: Spirits Bay, North Cape district. Kirk! April–May.
This only differs from O. albida in the shorter and broader much more waved leaves, and, in my opinion, would have been best treated as a form of that plant.
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.
North Island: North Cape to Taranaki and the East Cape, usually near the sea, but not common. April–May.
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, 16–15 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. Nov. Zel. i. 120. Shawia avicenniæfolia, Raoul, Choix, 19.
South Island, Stewart Island: Abundant throughout, ascending to 3000 ft. Akeake. January–February.
