 Description

Stoloniferous perennial with much-branched stems terminating in leafy rosettes and usually forming mats, 2–4 cm tall. Lvs mostly in basal rosettes; basal lvs slightly narrowed to broad sheathing petiole, densely sericeous on both surfaces including mid-vein but not petiole, keeled toward apex, narrow-oblong to spathulate, obtuse, (5)–8–12 × 2–4 mm; cauline lvs 1–2, narrow. Capitula c. 5–8 mm diam., solitary; subtending lvs < capitula; scape terminal, simple, erect, amongst lvs at flowering, elongating only to just above lvs at fruiting. Involucral bracts narrowly elliptic-oblong, subacute, 7–7.5 mm long; stereome yellow-green; lamina very pale brown, sometimes darker at base; gap and margins clear to mid-brown. Achenes glabrous, 1–1.2 mm long.
