Manual of the New Zealand Flora.

4. Olearia, Mcench

4. Olearia, Mcench.

Shrubs or trees. Leaves alternate, rarely opposite or fascicled, usually with white or buff tomentum beneath. Heads large or small, solitary or corymbose or paniculate, radiate or rarely discoid. Involucre broad or narrow; bracts imbricated in several rows, margins dry or scarious. Receptacle flat or convex, pitted. Florets few or many, rarely solitary; ray-florets female, in a single row, usually ligulate, spreading, rarely slender and filiform or altogether wanting; disc-florets hermaphrodite, tubular, 5-lobed. Anthers often acute at the base or with minute tails, rarely obtuse. Style-branches flattened, with short obtuse or rarely lanceolate appendages. Pappus of one or more rows of unequal scabrid bristles, often thickened at the tips. Achenes ribbed or striate, terete or slightly compressed.

In addition to the 35 species found in New Zealand, all of which are endemic, there are about 70 others, confined to Australia and Tasmania with the exception of 2 recorded from Lord Howe's Island. The genus is very closely allied to Aster, with which the late Baron von Mueller proposed to unite it, together with Celmisia and several other genera.

Chatham Islands: Abundant in moist places, near the margin of woods, &c. Hangatare. November–December.

A beautiful little plant, easily recognised by its small size, narrow leaves, slender peduncles, and purple flowers. I am indebted to Mr. Cockayne for a very interesting series of specimens showing the range of variation in the size and shape of the leaves. See his paper on "The Plant-covering of Chatham Island," Trans, N.Z. Inst. xxxiv. 288, for some remarks on the subject.

(1875) 336, t. 15.

Chatham Islands: In swampy places on the higher parts of the island and on cliffs, H. H. Travers! Enys! Cox! Keketerehe. November–February.

This comes very near to O. operina and O. angustifolia, but is sufficiently distinct in the broader leaves and more slender peduncles with fewer bracts.

4.O. operina, Hook. f. Fl. Nov. Zel. i. 114.—A stout sparingly branched shrub 6–12 ft. high; branches, leaves beneath, peduncles, and inflorescence densely clothed with soft white tomentum. Leaves often crowded at the tips of the branches, spreading, 2–4 in. long, ½–¾ in. broad, narrow obovate-lanceolate, acuminate, gradually narrowed into a short winged petiole, rigid, very thick and coria ceous, glabrous above; margins with numerous close blunt teeth with callous tips.

The Snares: Abundant, Kirk! Auckland Islands: Apparently rare,. Lyall, Bolton, Kirk!

A magnificent plant, nearly related to O. Colensoi, but at once distinguished by the open and far more robust habit, larger and broader leaves, which are tomentose on the upper surface as well as beneath, and by the scales of the involucre being in several series.

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.

North Island: Buchanan! The exact locality not known.

Founded on a single specimen in Mr. Kirk's herbarium stated to have been, collected by Mr. Buchanan in the year 1870 in some locality in the North Island. It is evidently a distinct species, not closely related to any other. It and O. Traversii are the only species found in New Zealand with large opposite leaves.

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 en tire, 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. page 284very short. Pappus 1-seriate. Achenes striate, silky.—Kirk, Forest Fl. t. 34; Students' Fl. 267. Eurybia Traversii, F. Muell. Veg. Chath. Is. 19, t. 2.

Chatham Islands: Abundant in woods. Akeahe. October–November.

Achenes small, faintly striate, pubescent.—Kirk, Students' Fl. 267. Eurybia furfuracea, D.C. Prodr. v. 267; Hook. f. Fl. Nov. Zel. i. 117. Haxtonia furfuracea, A. Cunn. Precur. n. 440. Shawia furfuracea, Raoul, Choix, 45. Aster furfuraceus, A. Rich. Fl. Nouv. Zel. 246.

North Island: Abundant from the North Cape to Hawke's Bay and Tara-naki. Wharangipiro; Akepiro. November–February.

A very common plant to the north of the East Cape, varying greatly in the size, shape, and texture of the leaves, the size of the flower-heads, and the number of florets. Two forms may perhaps be distinguished, one with broad heads containing 8–12 florets, the other with much narrower heads and 4 to 8 florets. To this state Mr. Kirk gives the varietal name of angustata,

12.O. Allomii, T. Kirk in Trans. N.Z. Inst. iii. (1871) 179.— A dwarf sparingly branched shrub 1–3 ft. high; branches stout, and with the inflorescence and leaves beneath clothed with smooth and shining silvery tomentum. Leaves alternate, rather close-set, 1–2 in. long, ¾–1½ in. wide, oblong-ovate or elliptic-ovate, obtuse, truncate or rounded and often unequal at the base, shortly petiolate, exces sively thick and coriaceous; veins reticulated above, midrib prominent below. Corymbs longer than the leaves, branched. Heads large, ½ in. diam., or even more when fully expanded; involucre broadly turbinate; scales laxly imbricate, tomentose, obtuse. Florets 15–20; rays about 8. Pappus-hairs unequal. Achenes grooved, hispid.—Students' Fl. 271.

North Island: Great Barrier Island, not uncommon, ascending to 2500 ft., Kirk! November–December.

page 285

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, ⅙–¼ 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.

Var. cordatifolia, Kirk, Students' Fl. 268.—Leaves orbicular, cordate at the base, very coriaceous. Heads broadly obconic; involucral scales densely woolly, inner villous at the tips. Florets about 20; those of the ray with long and narrow ligules.

Var. angustifolia, Cheesem.— Leaves 2–3½ in. long, linear-lanceolate to lanceolate or oblong-lanceolate, almost membranous, margins sinuate. Corymbs lax, much-branched. Heads large, in. long; rays long and narrow.

Var. capillaris, Kirk, l.c.—Small, stout or slender, densely or sparingly branched. Leaves small, ¼–1 in. long, ovate or rounded, membranous or sub-coriaceous, silky above when young. Heads 3–12, in sparingly branched corymbs longer than the leaves; pedicels very slender; involucral scales glabrate or slightly villous. Florets 8–12.—O. capillaris, Buch. in Trans. N.Z. Inst. iii. 1871) 212.

Dall! source of the Poulter River (Canterbury), Cockayne!

Perhaps the most variable species of the genus, but generally to be recognised in all its forms by the thin white and peculiarly satiny tomentum on the under-surface of the leaves.

Only differs from O. Haastii in the more erect habit and longer and narrower leaves. Intermediate forms have been collected, but the usual aspect of the plant is distinct.

24.O. (?) coriacea, Kirk, Students' Fl. 276. — A sparingly branched rigid shrub 6–8 ft. high; branches erect or ascending, rather stout, pubescent. Leaves alternate, ½–⅔ in. long, ovate or orbicular-ovate, obtuse, shortly petiolate, excessively thick and coriaceous, glabrous above, white with appressed tomentum beneath; margins recurved. Flowers not seen, but the peduncles of the previous year's inflorescence are about twice as long as the leaves, and are apparently branched at the top.

South Island: Marlborough—Awatere Valley and Mount Fyffe, Kirk!

Apparently a very distinct species, the exact position of which must remain doubtful until flowering specimens have been obtained.

Var. cymbifolia: Mountain districts in the South Island, but local; most plentiful in Nelson and Marlborough.

A variable plant, especially in the size and shape of the leaves, the extent to which the leaf-margins are revolute, the size of the heads, and the number of florets. There is a specimen in Mr. Petrie's herbarium with the heads collected in 3–5-flowered corymbs.

North and South Islands: From the East Cape southwards to Oamaru. and Greymouth; often local, usually near the coast. Sea-level to 1500 ft. Akiraho. April–May.

The heads never contain more than one floret, which is invariably tubular and hermaphrodite. On account of the constancy of this character Mr. Kirk has proposed to revive Forster's genus Shawia, but, I think, quite unnecessarily. In O. avicenniæfolia the florets are sometimes reduced to 2, and occasionally-there is no ray-floret, thus absolutely bridging over the gap between O. Forsteri and the remaining Oleariæ.
