petioles stout or slender, ½–1½ in. long. Panicles very large, wide-spreading, much-branched. Heads numerous, ¼–⅓ in. diam., campanulate; scales of the involucre in several series, lanceolate or ovate-lanceolate, obtuse or subacute, tomentose or villous or nearly-glabrous. Florets 12–24; ray-florets the most numerous; ligules short, broad. Pappus-hairs white or reddish, unequal. xchenes quite glabrous or rarely with a few scattered hairs.—Kirk, Forest Fl. t. 114; Students' Fl. 269. Eurybia Cunninghamii, Hook. f. Fl. Nov. Zel. i. 117, t. 30. Brachyglottis Rani, A. Cunn. Precur. n. 465.

Var. colorata, Kirk, Students' Fl. 269.—Leaves narrower, oblong-lanceolate to lanceolate. Otherwise as in the type.—O. colorata. Col. in Trans. N.Z. Inst. xii. (1880) 362.

North and South Islands: Abundant in woods from the North Cape to Marlborough and Nelson. Sea-level to 2500 ft. Heketara. October–November.

A very variable plant. The leaves are sometimes coarsely toothed and ac other times almost entire; the involucral scales vary from linear-oblong and densely tomentose to linear and almost glabrous. Mr. Kirk describes the var. colorata as having the scales nearly glabrous, but they are densely tomentose in Mr. Colenso's type specimens and in all others that I have seen.


17. O. excorticata, Buch. in Trans. N.Z. Inst. vi. (1874) 241.—A small much-branched shrub or small tree 12–15 ft. high, with a trunk 1 ft. in diam.; bark loose, papery; branchlets grooved, and with the panicles, petioles, and leaves beneath clothed with dirty-white or buff tomentum. Leaves alternate, 1½–4 in. long, ½–1 in. broad, lanceolate or oblong-lanceolate, acute or acuminate, shortly petiolate, coriaceous, glabrous and finely reticulated above; lateral veins spreading, but hardly at right angles; margins flat, obscurely sinuate-dentate. Panicles longer than the leaves, branched, corymbose; pedicels slender, densely tomentose. Heads numerous, small, 1/61/5 in. long; involucre narrow-turbinate; outer scales small, ovate, tomentose; inner linear-oblong, obtuse, villous at the tips. Florets about 12; ray-florets 5–7. Pappus-hairs slender, in one series. Achenes grooved, hispid.— Kirk, Students' Fl. 270.

North Island: Tararua Mountains, Mitchell! Mount Holdsworth, T. P. Arnold! South Island: Mr. H. J. Matthews has sent specimens from a cultivated plant raised from seed obtained in the Nelson District.


18. O. suavis, Cheesem. in Trans. N.Z. Inst. xxiv. (1892) 409.—A densely branched shrub or small tree 6–18 ft. high; branches stout; branchlets, panicles, and under-surface of leaves clothed with pale-yellowish or fulvous tomentum. Leaves alternate, ¾–1½ in. long, ½–¾ in. broad, Imear-oblong or oblong to ovate, obtuse at both ends, shortly petiolate, coriaceous or almost membranous, entire or obscurely sinuate, glabrous above; lateral veins conspicuous beneath, spreading almost at right angles. Panicles much longer than the leaves, slender, corymbose, much-branched; pedi-
