Characteristics

Dwarf twiggy mat-forming subshrub, branches diffuse or erect to ±150 mm, very slender but stiff, thinly white-woolly, closely leafy, often with dwarf axillary shoots. Leaves up to 14 x 2 mm but often only ±4 x 0.5 mm, linear or linear-lanceolate, margins strongly revolute, apex subacute, base broad, very shortly decurrent, upper surface thinly and loosely woolly, lower white-woolly. Heads heterogamous, campanulate, ±3.5-4(-5) x 2-3(-4) mm, 2-5, rarely more, clustered at the tips of the branchlets. Involucral bracts in ±4 series, graded, closely imbricate, inner about equalling flowers, tips obtuse, crisped, pellucid, whitish, straw-coloured, tawny or sometimes reddish, not radiating. Receptacle shortly toothed. Flowers 18-36, 5-10 female, 14-29 homogamous. Achenes ±1 mm long, with myxogenic duplex hairs. Pappus bristles many, about equalling corolla, scabridulous, bases cohering by patent cilia.
