Leaves alternate, 3–7 in. long, ⅓–1 in. broad, narrow-linear or linear-lanceolate to linear-oblong, acute or acuminate, shortly petioled, quite entire or obscurely sinuate-toothed, coriaceous, glabrous and reticulated above; midrib very stout and prominent beneath, lateral veins strong, spreading at right angles and dividing the under-surface into numerous sunken interspaces; margins recurved. Panicles towards the tips of the branches, branched, slender, forming a corymbose mass 4–8 in. diam. Heads numerous, small, 1/5 in. diam., on slender pedicels; involucre turbinate; scales few, laxly imbricate, tomentose or villous. Florets small, 8–12, about half of them shortly rayed.

20. O. alpina, Buch. in Trans. N.Z. Inst. xix.

Leaves 5–6 in. long, ¼ in. broad, linear, entire; midrib very stout, lateral veins close, diverging at right angles, forming a series of lacunæ on each side of the midrib. Panicles large, much-branched. Heads numerous; involucre turbinate. Flowers not seen. Pappus-hairs reddish.—Kirk, Students Fl. 270.

North Island: Wellington—Tararua Mountains and hills towards Wanganui, Buchanan.

I have seen no specimens of this, and the above description is adapted from Buchanan's. It is evidently near to O. lacunosa, but appears to have narrower leaves.
