Dwarf shrub, twiggy, compact, branches erect or prostrate and then rooting, glabrous or loosely woolly at first, sometimes glandular-pilose, nearly always so on the upper parts and on the peduncles, densely leafy. Leaves up to 3 cm long including the broad, half-clasping petiole-like base, blade oblong in outline, closely pinnatisect or bipinnatisect, lobes up to 4 mm long, the young unfurled leaves densely white-woolly, glabrous at maturity though sometimes with stalked glands. Heads radiate, solitary or up to 3 corymbosely arranged at the branch tips. Involucre turbinate, bracts c. 12, (6-)7-8 mm long, about equalling the disc, glandular-pilose, often cobwebby at the base as well, nerves resinous. Rays c. 13, long, spreading, they and the disc bright canary yellow, corolla lobes of the disc flowers with a median resinous line. Achenes c. 3 mm long, cylindric, ribbed, glabrous.
