Raoulia.], laxly imbricated or somewhat remote, spreading or erecto-patent, $1⁄8$–$1⁄5$ in. long, linear-ligulateor linear-oblong, acute or obtuse, flat or nearly so, 1-nerved, glabrous or slightly silky, sometimes with a minute pencil of hairs at the tip. Heads rather large, ¼–⅓ in. diam.; involucral bracts in 3–4 series; outer green, ovate-oblong, acuminate; inner longer, linear-oblong, with white radiating tips. Florets numerous, 30–50; female in 2 series, rather less in number than the hermaphrodite ones. Achene puberulous. Pappus-hairs copious, soft, not thickened at the tips.—''Handb. N.Z. Fl. 149; Kirk, Students' Fl.'' 303.

6. R. subsericea, Hook. f. Fl. Nov. Zel. i. 136.—Stouter than R. glabra, and more closely branched, forming smaller and more compact patches with shorter erect branches. Leaves rather longer and broader than in R. glabra, closely imbricated, $1⁄6$–$1⁄4$ in. long, linear-oblong, obtuse or subacute, flat or nearly so, usually sparingly clothe(i with thin silvery tomentum or rarely almost glabrous. Heads rather larger, ⅓ in. diam.; involucral bracts broader, the innermost with larger and more conspicuous white radiating tips. Florets similar to those of R. glabra, but fewer in number. Achene glabrous. Pappus-hairs copious, soft, slightly thickened at the tips.—Handb. N.Z. Fl. 150; Kirk, Students' Fl. 303.

7. R. Parkii, ''Buch. in Trans. N.Z. Inst.'' xiv. (1882) 355, t. 34, f. 3.—Stems 1–6 in. long, prostrate, creeping and rooting, often densely matted and forming large patches; branches short, erect or ascendmg, ½–1 in. long. Leaves closely imbricated, spreading and recurved, $1⁄10$–$1⁄6$ in. long, obovate-spathulate, obtuse, clothed with white or buff woolly appressed tomentum except towards the base, which is usually glabrous. Heads $1⁄6$–$1⁄4$ in. diam., sessile among the terminal leaves; involucral bracts in 2–3 series; the outer short, tomentose on the outside; the inner longer, linearoblong, obtuse, with white radiating tips. Florets 15–25, the females about equal to the hermaphrodite ones in number. Achene puberulous. Pappus-hairs slightly thickened at the tips.
