Straggling well-branched subshrub up to 1 m tall, branches virgate, white-woolly, closely leafy becoming nude and pedunculoid below the inflorescence. Leaves mostly 6-20 x 2-12 mm, panduriform, upper part broadly elliptic to suborbicular, abruptly contracted about the middle, apex very obtuse, base broad, ear-clasping, margins crisped-undulate, both surfaces greyish-white woolly, upper less densely so. Heads homogamous, campanulate to subglobose, 4-5 x 3-5 mm, many in small corymbose clusters often corymbose-paniculately arranged. Involucral bracts in 5 series, graded, loosely imbricate, inner about equalling flowers, tips not radiating, concave, very obtuse, more or less undulate-crisped, opaque creamy white to pale primrose yellow, or rosy. Receptacle with fimbrils equalling ovaries. Flowers 14-30. Achenes 0.75 mm long, barrel-shaped, ±8-ribbed, glabrous. Pappus bristles many, a little shorter than corolla, scabrid, bases cohering strongly by patent cilia. Flowers between September and February, mainly in December and January.
