Characteristics

Mat-forming perennial herb with prostrate rooting branches radiating from a stout woody stock and giving rise to innumerable crowded leaf rosettes, flowering stems terminal, 50-400 mm tall, leafy. Radical leaves 10-40(-70) x 2-3(-5) mm, linear-lanceolate, acute, apiculate, base broad, clasping, margins weakly revolute, both surfaces silvery white-felted, lower paler than upper which is sometimes merely cobwebby, prominently 3-5-nerved; cauline leaves similar but often shorter, closely imbricate. Heads heterogamous, campanulate, 12-15 mm long, ±25 mm across the fully radiating bracts, mostly solitary, occasionally 2 or 3 corymbosely arranged. Involucral bracts in ±8 series, graded, loosely imbricate, inner much exceeding flowers, glossy white, very pale to dark chestnut brown or reddish brown outside in upper half. Receptacle shortly honeycombed. Flowers 153-443, 15-28 female, 138-424 homogamous. Achenes 1.5 mm long, glabrous. Pappus bristles many, equalling corolla, barbellate above, bases not cohering. Flowering between December and July, chiefly in February and March.
