 Description

Stoloniferous perennial; stems 1-few, ascending to erect, simple or sparingly branched, 20–70 cm tall. Lvs either basal and cauline at flowering, or basal lvs withered or 0; cauline lvs apetiolate, densely white-tomentose on lower surface, glabrous on upper, plane or somewhat keeled, lanceolate, narrow-oblanceolate to linear, cuneate or not narrowed to base and amplexicaul, acute, 30–200 × (1)–4–12 mm; basal lvs cuneate; uppermost lvs linear-lanceolate. Capitula c. 1.5–3 mm diam., few to numerous in dense ± globular terminal clusters, often smaller axillary clusters below; longest subtending lvs 1–4× diam. of cluster. Involucral bracts ovate- to elliptic-oblong, acutely narrowed or rounded to blunt apex, 4–4.5 mm long; stereome green; lamina pale brown; gap and margins clear, partly tinged reddish purple. Achenes minutely papillate, c. 0.6 mm long.
