Characteristics

Subshrub, main stems up to ±300 mm long, branched, prostrate or diffuse, flowering branchlets ascending, all closely leafy throughout. Leaves imbricate, those on sterile shoots mostly 7-15 x 2-6 mm, subequal, narrowly obovate, lower part appressed, webbed to stem, upper part ascending or spreading, often somewhat recurved, tip acute, apiculate, hooked, leaves on flowering twigs often much narrower, ±1.5-3 mm broad, somewhat spreading or strongly appressed, oblong-lanceolate or oblong, acute or subacute, uppermost often tipped with papery brown scales, all leaves wholly enveloped in silvery, silky 'tissue-paper' indumentum. Heads heterogamous, turbinate-campanulate, mostly 15-20 mm long, nearly double that across the radiating bracts, solitary at tips of branchlets in upper leaf axils, these branches peduncle-like when leaves much reduced and appressed. Involucral bracts in ±7 series, loosely imbricate, graded, inner much exceeding flowers, linear-lanceolate, mostly subacute, sometimes acute, glossy white or pale to deep rose, or white tipped rose, outer ovate-lanceolate, subobtuse to acuminate, golden-brown sometimes tinged rose. Receptacle very shortly honeycombed. Flowers 58-282, 6-24 female, 52-243 homogamous. Achenes 1 mm long, cylindric, with myxogenic duplex hairs. Pappus bristles many, equalling corolla, tips subplumose, shaft scabrid, bases lightly fused.

Prostrate or straggling, closely leafy, silvery subshrub, up to 300 mm tall. Leaves imbricate, suberect or spreading, often recurved above, oblong-lanceolate, hooked, 7-15 x 2-6 mm, silvery silky with tissue paper-like hairs. Flowerheads terminal, solitary on scaly peduncles distinct from leafy shoots, disciform, top-shaped, mostly 15-20 x 30-40 mm, bracts ± 7-seriate, lanceolate, acute, shiny white to pink, outer often flushed brown, glabrous; florets ± 60-28.
