packed, imbricated in many series, 1/81/6 in. long, broadly obovate-spathulate or cuneate, rounded or almost truncate at the tip, membranous, upper part clothed on both surfaces with long straight hairs which project beyond the leaf, but the extreme tip naked on both sides though concealed by the hairs, lower portion of the leaf glabrous on both surfaces. Heads small, 1/10 in. diam., sunk among the terminal leaves; involucral bracts numerous, linear, obtuse, glabrous, the inner with short white radiating tips. Florets 10–14; corolla dark-crimson. Achene clothed with long silky hairs. Pappus-hairs few, rigid, thickened at the tips.—Kirk, Students' Fl. 305.

North Island: Mount Holdsworth, Tararua Range, alt. 4500 ft., Buchanan! T. P. Arnold! January.

I have only seen very imperfect specimens of this, and the above description is mainly founded on that originally published by Buchanan. Its nearest ally appears to be R. manimillaris.


15. R. Buchanani, T. Kirk, Students' Fl. 307.—Apparently forming hard compact masses. Branches short, stout, with the leaves on ¼ in. diam. Leaves closely packed, imbricated in several series, 1/81/6 in. long and almost as broad at the tip, broadly cuneate, truncate, membranous; upper surface with the lower twothirds quite glabrous, above that clothed with straight hairs which project just beyond the tip, forming a kind of fringe; undersurface with the lower half loosely cottony, the upper half glabrous, more or less corrugated or wrinkled. Heads unknown.

South Island: Otago—Mount Alta, Buchanan!

A very remarkable plant, the exact position of v?hich must remain doubtful until the flowers have been observed. It is probably nearest to P. Goyeni. The leaves difier from those of any other species in the broad truncate tips densely hairy above, but glabrous and wrinkled beneath.


16. R. Goyeni, T. Kirk in Trans. N.Z. Inst. xvi. (1884) 373.—Forming hard compact greenish masses from a few inches to 2 or 3 ft. long, but rarely more than 6 or 8 in. high. Branches very short, closely compacted and often subangular from mutual pressure, with the leaves 1/51/4 in. diam. Leaves very closely packed, densely imbricated in many series, 1/81/6 in. long, linear-oblong, sessile by a broad base, rather wider and truncate at the tip, glabrous beneath, on the upper surface bearing near the tip a dense tuft of straight white hairs slightly longer than the leaf, the extreme upper margin naked although concealed by the hairs. Heads small, deeply sunk among the leaves at the tips of the branches; involucral bracts in 2 series; the outer linear-spathulate, scarious, bearing a tuft of hairs at the tip; the inner linear, scarious, obtuse, some of them with short hardly radiating white tips. Florets few. Achene hispid, with a thickened areole. Pappus-hairs few, thickened upwards.—Students' Fl. 306.
