A creeping perennial herb forming tight mats up to ca. 1 m wide, densely covered all over with long silky silver hairs. Rhizomes interwoven, ± horizontal on soil surface or ascending and tightly packed, densely hairy; branches us. in clusters, up to 4 radiating from around a flowering node; leaves clustered near apex, remaining crowded or occ. older ones becoming up to 0.8 cm apart. No short shoots. Roots moderately stout for the size of the shoots, up to 0.5 mm diam. Leaves 1-pinnatifid, 4-10 × 2-3 mm; blade coriaceous, dark green but hidden under a dense layer of woolly hairs; pinnae 4-8 pairs, very close-set and not easily discerned under the hairs, cut to rhachis, obovate, obtuse, without teeth. Peduncles longer than leaves, 1-2 cm, nude, densely woolly. Monoecious. Heads 3-10 mm diam.; surface convex; involucre subcampanulate; phyllaries ca. 20 in 2 subequal rows, oblong, grey-green but densely villous, with wide brown scarious margin, not growing after anthesis; pistillate florets 20-50 in 1-2 rows, 2.75 mm long, straight, pale yellow or yellow-red, sts with 1-2 dark stripes along corolla and ovary; corolla ca. 3 times as long as wide, with equal teeth; staminate florets more numerous. Achenes up to 1.6 × 0.6 mm, zb compressed, biconvex, golden-brown, scarcely wrinkled. Flowers in summer.
