Characteristics

Mat-forming perennial herb, sterns decumbent and often rooting at the base, then erect to ±150 mm, simple or branching from the base, leafy. Leaves rosetted initially, oblanceolate, uppermost lanceolate, up to 50 x 5(-7) mm, becoming shorter and narrower upwards and passing into bracts with brown scarious tips, apex subacute to acute to acuminate, apiculate, base broad, clasping, both surfaces and the stems enveloped in silvery silky skin-like indumentum. Heads homogamous, cylindric, ±3-4 x 1.5-2 mm, many in dense, flat-topped clusters 10-20 mm across, solitary at the branch tips, surrounded by brown papery bracts and webbed together with grey silky-woolly hairs. Involucral bracts in 3 series, graded, equal, equalling the flowers, very loosely imbricate, silvery, pellucid, at least the outer ones golden-brown above, tips blunt, lacerate, crisped, not radiating. Receptacle shortly honeycombed. Flowers 7-14. Achenes not seen, ovaries glabrous. Pappus bristles very few, (often some flowers epappose, others with 1 or 2 bristles), shorter than corolla, subplumose above, smooth below, bases not cohering.
