[Olearia.

Very similar to O. odorata in habit and appearance, but the fascicles are larger and much more lax, the peduncles longer, the involucral bracts not viscid nor glandular, and the florets much fewer in number. I have only seen two specimens.


34. O. virgata, Hook. f. Handb. N.Z. Fl. 128.—An erect much-branched shrub 4–10 ft. high, often forming dense thickets; branches spreading, stout or slender, tetragonous or almost terete, smooth or grooved, glabrous or pubescent when young; bark dark red-brown. Leaves opposite or in opposite fascicles, ¼–½ in. long, linear-obovate or linear-spathulate, obtuse, narrowed into a short petiole or sessile, coriaceous, glabrous or silky above, clothed with white appressed tomentum beneath. Heads solitary or fascicled, on short arrested opposite branchlets, shortly pedunculate or almost sessile. Involucre broadly turbinate; bracts in about 3 series, linear-oblong, tomentose or villous or almost glabrous. Florets 5–12; ray-florets 3–6, short, slender; disc-florets often with villous tips to the corolla-lobes. Achenes small, linear, glabrous or slightly pubescent.—Kirk, Students' Fl. 275. O. quinquefida, Col. in Trans. N.Z. Inst. xxviii. (1896) 596. O. aggregata. Col. l.c. 597. O. parvifolia, Col. l.c. 598. Eurybia virgata, Hook. f. Fl. Nov. Zel. i. 119.

Var. ramuliflora, Kirk, Students' Fl. 276.—Leaves in opposite fascicles of 2–6, rather larger, ¼–½ in. long, flat. Heads more numerous, in fascicles of 2–6; peduncles slender, often ¼ in. long or more, silky. Involucres tomentose or villous. Florets 7–12.—O. ramuliflora, Col. in Trans. N.Z. Inst. xxii. (1890) 467.

Var. lineata, Kirk, Students' Fl. 276.—Branchlets more slender, spreading, often silky-pubescent. Leaves ½–1½ in. long, very narrow-linear, glabrate or silky above, tomentose beneath; margins much revolute. Heads fascicled; peduncles slender, silky. Involucre villous or tomentose. Florets 12–20.

North and South Islands: From the Thames Valley and Rotorua southwards; not uncommon. Sea-level to 3000 ft. December–January.


35. O. Solandri, Hook. f. Handb. N.Z. Fl. 128.—An erect much-branched shrub 5-15 ft. high; branches stout, spreading, angled, often viscid, usually more or less clothed with pale-yellowish pubescence. Leaves of young plants opposite, ⅓–½ in. long, linear-obovate or -spathulate, narrowed into short petioles, membranous, flat, white beneath; of mature plants in opposite fascicles, 1/51/3 in. long, narrow-linear or linear-obovate, obtuse, narrowed into very short petioles, coriaceous, glabrous above, beneath clothed with pale-yellowish tomentum; margins recurved. Heads ¼–⅓ in. long, solitary, sessile, terminating short lateral branchlets. Involucre narrow-turbinate; scales in 3–4 series, numerous, imbricate, obtuse or subacute, bright fulvous, pubescent or viscid. Florets 8–20; ray-florets 5–14, ray short. Achenes grooved, pubescent.—Kirk, Students' Fl. 276. O. fasciculifolia. Col. in Trans. N.Z. Inst. xxv. (1893) 330. O. consimilis, Col. l.c. xxviii. (1896) 596. Eurybia Solandri, Hook. f. Fl. Nov. Zel. i. 119.
