Characteristics

Prostrate or diffuse grey-or white-woolly herb, possibly perennial, root woody, branches several from the crown, up to 450 mm long, sometimes rooting in the lower parts, loosely branched, branchlets thinly greyish-white woolly, leafy. Leaves mostly 8-20 x (2-)5-12 mm, considerably smaller immediately below the heads, spathulate to obovate, apex mostly rounded, tip or sometimes whole leaf folded and recurved, base narrowed, half-clasping, both surfaces greyish-white woolly, the wool sometimes closely woven. Heads homogamous or heterogamous, cylindric, ±5 x 2-3 mm, solitary or aggregated in small glomerules ±10 mm diam. terminating the branches and short lateral branchlets in the upper axils, surrounded by reduced leaves webbed together with wool. Involucral bracts in 4 series, outermost short, lanceolate, surrounded by 1 or 2 leaves webbed to them with wool, inner about equalling the flowers, subequal, loosely imbricate, soon caducous, tips subpellucid, or opaque at the extreme tips, mostly golden-brown, sometimes crimson, subacute to more or less truncate, then often emarginate, not radiating. Receptacle scarcely honeycombed. Flowers 9-26, 0-5 female, 9-26 homogamous. Achenes 0.75 mm long, glabrous or with myxogenic hairs. Pappus bristles in 2-3 series, very many, very delicate, equalling corolla, scabrid, bases cohering lightly by patent cilia.
