13. R. mammillaris, ''Hook. f. Handb. N.Z. Fl. 150.—Forming hard compact masses similar in size and aspect to those of R. eximia.'' Branches short, stout, with the leaves quite ¼ in. diam. Leaves most densely packed, imbricated all round the branches in many series, spreading, $1⁄12$–$1⁄8$ in. long, obovate-cuneate or spathulate, rounded or almost truncate at the tip, membranous, glabrous or nearly so in the lower half, in the upper half clothed on both surfaces with a dense tuft of straight hairs which project just beyond the tip and conceal the leaf. Heads $1⁄6$–$1⁄4$ in. diam., sunk among the leaves at the tips of the branches; involucral bracts in about 2 series, the inner linear-oblong, scarious, with conspicuous white obtuse or subacute radiating tips. Florets 10–12, the hermaphrodite ones more numerous than the females. Achene clothed with long silky hairs, and with a thickened areole at the base.
