Leaves crowded-rosulate and prostrate, very variable, mostly 3–10 x 1–2.5 cm., exceptionally to c. 21 cm. long or 7.5 cm. wide, elliptic to oblanceolate in outline sometimes elongate-spathulate, gradually or abruptly narrowed from about the middle into a linear petiole-like base, apex subacute to rounded, base cuneate to long-attenuate becoming dilated and ± stem-clasping, margins entire or repand, irregularly toothed, subruncinate or subpinnatifid, midrib broad composed of numerous ± distinct veins running parallel to diverge in pairs at regular intervals, prominent beneath; upper surface glabrous or thinly pilose; lower surface densely white-felted.
Perennial herb, stems rhizomatous or prostrate, forming caespitose mats, 0.05-0.15 m high. Leaves petiolate, elliptic to pinnatifid, margins entire or lobed, upper surface glabrous or hirsute, 15-180 mm long; involucral bracts in few rows, apex of outer bracts erect or reflexed, glabrous or hirsute. Ray florets female, fertile, limb yellow. Disc florets many, hermaphrodite, corolla yellow. Filaments smooth. Flowering time Sept., Oct. Pappus of scales in 2 series of subequal length, 0.2-0.5 mm long. Cypselae glabrous or minutely pubescent, smooth or transversely rugose, abaxial ribs ± inconspicuous.
Ray-florets; rays yellow, spreading, 10–20 x 4–7 mm., narrowly-elliptic, narrowly 3-lobed at the apex; achenes 1–2.5 mm. long, turbinate, obscurely c. 8-ribbed, the ribs transversally rugose or muricate, glabrous except for a short delicate coma; pappus variable, sometimes wanting, 2–3-seriate, of delicate scarious overlapping narrowly lanceolate scales to 1 mm. long, the inner tapering to an attenuate apex, the outer much smaller and blunt.
Tufted, white-felted perennial to 15 cm. Leaves elliptic, shortly petiolate, with recurved teeth, discolorous, white-felted below, sometimes roughly hairy above. Flower heads radiate, solitary, on short, densely hairy scapes, yellow with greenish reverse. Achenes glabrous or ciliate, with a basal circlet of delicate hairs, sometimes almost wanting, pappus rudimentary to 1.5 mm.
Involucres 8–11(14) x 6–9 mm., broadly obconic; phyllaries few-seriate, narrowly hyaline on the margins, glabrous occasionally pilose outside; outer phyllaries c. 6 mm. long, narrowly ovate, acute to attenuate at the apex; the inner phyllaries up to c. 10 x 3 mm. and oblong-lanceolate, rounded-mucronate at the apex.
Perennial herb, up to 200 mm tall. Leaves in a basal rosette. Involucral bracts biseriate. Pappus scales very short or rudimentary; basal coma of short delicate hairs. Flowers with pale yellow rays, sometimes tinged greenish grey below, disc yellow.
Scapes several from the rootcrown, up to c. 8 cm. tall but usually shorter than the leaves, simple, glabrous or white-araneose with ± obvious scattered patent soft reddish-purple pilose hairs to c. 1 mm. long.
A mat-forming scapose perennial herb, stoloniferous; rootstock woody with numerous thong-like lateral roots.
Disk-floret corollas yellow, up to c. 6 mm. long, achenes and pappus similar to those of the ray-florets.
