Leaves numerous, small, crowded, spreading and recurved, ⅛–⅕ in. long, linear-obovate or linear-oblong or oblong-obovate, obtuse, narrowed into a very short petiole, coriaceous, glabrous or hoary above, beneath clothed with dense white tomentum; margins recurved. Heads numerous, in small terminal corymbs, shortly pedicelled, turbinate, ¼ in. long; involucral bracts in several series; the outer shorter, ovate-oblong, tomentose; inner linear-oblong, with short white obtuse radiating tips. Receptacle with many white-tipped scales similar to the inner involucral bracts. Florets 6–20. Achenes glabrous, striate. Pappus-hairs slender.—''Hook. f. Fl. Nov. Zel. i. 132; Handb. N.Z.
