[Olearia.

longer, linear-oblong, almost glabrous or pubescent at the tips. Florets 4–8; ray-florets 2–4, short, broad. Achenes grooved, pubescent.—Students' Fl. 272. O. angustata, Armst. in Trans. N.Z. Inst. xiii. (1881) 337.

South Island: Canterbury—Ashburton Mountains, Potts! Upper Rangitata, Armstrong! Otago—Resolution Island and Preservation Inlet, Enys! 1500–3500 ft. January.

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.


25. O. nummularifolia, Hook. f. Handb. N.Z. Fl. 127.—A much and closely branched shrub 2–10 ft. high; branches stout, woody, scarred; younger ones often viscid, more or less clothed with whitish or yellowish stellate tomentum or almost glabrous. Leaves alternate, close-set, erect or spreading, 1/51/2 in. long, almost orbicular to broadly oblong or obovate, rounded at the tip, very shortly petiolate, excessively thick and coriaceous, shining and reticulate above, clothed with appressed stellate tomentum beneath; margins recurved. Heads ⅓–½ m. long, solitary, on axillary peduncles longer or shorter than the leaves. Involucre narrow-turbiuate; scales in several series, closely imbricating, tomentose or pubescent or almost glabrous; outer short and broad; mner linear, obtuse. Florets 6–12; ray-florets 3–5, rather broad. Achenes pubescent.—Kirk, Students' Fl. 273. O. Hillii, Col. in Trans. N.Z. Inst. xx. (1888) 194. Eurybia nummularifolia, Hook. f. Fl. Nov. Zel. i. 118.

Var. cymbifolia, Hook. f. Handb. N.Z. Fl. 732.—Leaves spreading or deflexed, oblong, obtuse, convex above, margins much revolute all round, hence boat-shaped with the cavity beneath; more or less clothed with white stellate tomentum. Heads as in the typical form, but scales usually more tomentose.

North and South Islands: Mountain districts from the East Cape and Taupo to Foveaux Strait, but local to the south of Lake Wanaka. Altitudinal range from 2000 ft. to 4500 ft., but descending to sea-level in Colac Bay, Southland. 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.
