Characteristics

Shrubby, much-branched perennial, either sprawling or forming a dense rounded bush or mat, main stems 3-5 mm diam., branches up to 450 mm long, old parts becoming nude, young branches grey-woolly-felted, closely leafy throughout. Leaves spreading, eventually reflexed, 4-10 x 1 mm, linear-lanceolate, apex obtuse, base slightly broadened, half-clasping, margins strongly revolute, upper surface thinly woolly, lower surface scarcely visible, greyish-white woolly-felted. Heads homogamous, campanulate, ±4 x 3 mm, ±10-15 in dense glomerules 10 mm across at the branch tips, soon overtopped by young growth. Involucral bracts in ±5 series, soon caducous, imbricate, graded, outermost reduced, acute, webbed together and to adjoining heads, innermost about equalling flowers, not radiating, glabrous, very obtuse, erose, somewhat concave, translucent, pale golden-brown. Receptacle shortly honeycombed. Flowers ±15-23. Achenes not seen, ovaries with myxogenic duplex hairs. Pappus bristles very many, scabrid, bases cohering lightly by patent cilia.
