Description
Stoloniferous perennial; stems 1-few, usually ascending, sometimes erect, usually simple, rarely sparingly branched, (2)–5–20–(40) cm tall. Lvs usually mostly basal at flowering; basal lvs short-petiolate, densely white-tomentose on lower surface usually including mid-vein, usually moderately to densely, sometimes sparsely tomentose on upper, plane, narrow- to broad- obovate or oblanceolate, long-cuneate, usually obtuse, sometimes acute, shortly mucronate, (5)–15–40–(60) × (2)–5–12 mm; cauline lvs usually becoming much reduced upwards, often oblong, acute, finally apetiolate and broad-based. Capitula c. 1–2 mm diam., (5)–8-numerous in dense ± globular terminal clusters, very rarely smaller axillary clusters below; longest subtending lvs 0.5–1.5× diam. of cluster. Involucral bracts elliptic to oblong-elliptic, obtuse to subacute, 3.5–4 mm long; stereome green, sometimes tinged reddish purple toward apex; lamina yellow to pale brown or orange; gap and margins usually tinged pinkish purple, sometimes clear. Achenes minutely papillate, c. 0.7 mm long.
