Morphology General Habit
A perennial herb, usually acaulescent, from a woody rootstock; roots numerous spreading thong-like.
Morphology Stem
Stems sometimes developed but abbreviated, erect to c. 5 cm. tall, simple or with a few short branches, and with 1–3 persistent leaf bases.
Morphology Leaves
Leaves few to numerous, prostrate discolorous subsessile, 6–20 x 1.5–12 cm., oblong-elliptic, oblanceolate-elliptic or ± orbicular, rounded and somewhat cuspidate at the apex or obtuse, broadly cuneate below narrowing to a winged midrib up to c. 2 cm. long, somewhat stem-clasping at the base, margins sparsely denticulate or serrulate, slightly revolute, green and glabrous on upper surface, white araneose-sericeous beneath (the indumentum sometimes peeling off), strongly 5(7)-nerved from the base, venation finely reticulate and prominent on both surfaces, or obscured by the indumentum beneath.
Morphology Reproductive morphology Inflorescences Capitulum
Capitula subsessile, 1–7, solitary or densely clustered in the leaf rosette.
Morphology Reproductive morphology Inflorescences Bracts Involucre
Involucres mostly 25–36 mm. long, 20–50 mm. in diam. in the upper part, broadly obconic-campanulate.
Morphology Reproductive morphology Inflorescences Bracts Phyllaries
Phyllaries stiffly slightly diverging, greenish to straw-coloured, chartaceous, sharply ciliolate on upper margins otherwise glabrous, the outermost usually not extending onto the capitulum stalk; the outer phyllaries from c. 7 mm. long and linear-lanceolate, usually somewhat falcate, tapering to a pungent apex; the inner phyllaries to c. 35 mm. long and narrowly lorate-lanceolate, ± scarious-winged in the lower part, inrolled and long-acuminate finely pungent to the apex; innermost phyllaries somewhat shorter, membranous winged and sharply cuspidate.
Morphology Reproductive morphology Flowers Corolla
Corollas creamy to brownish usually with purplish lobes, 10–13 mm. long, infundibuliform; lobes 5–6.5 mm. long, linear, erect; achenes c. 2 mm. long, narrowly turbinate, densely long-ascending hispid; pappus copious, several seriate of plumose white setae 8–11 mm. long, shorter on the outside, seta bristles 0.5–1 mm. long.

Morphology General Habit
Acaulescent perennial herb.
Morphology Leaves
Leaves all basal, forming a rosette, oblanceolate to obovate to almost round, 4–15 cm long, 1–8(–12.5) cm wide, cuneate into a membranous slightly expanded base, margins minutely serrulate, apex obtuse to rounded, minutely apiculate, dark green and glabrous above, white-tomentose beneath, with 1–2 prominent ascending subbasal veins on each side.
Morphology Reproductive morphology Inflorescences Capitulum
Capitula 1–4, subsessile, precocious on surface of soil, or in centre of leaf rosette, discoid; involucre 25–32(–40) mm long; phyllaries ± 170, multiseriate, the outer narrowly lanceolate, glabrous, shiny white or pallid with paler membranous, minutely shortly pectinate-ciliate margins, becoming progressively longer and broader-margined inwards, the longest ± 25(–35) mm long, acuminate, pungent, the innermost ± 35 shorter, membranous, lanceolate to oblong, acuminate, rarely tomentellous.
Morphology Reproductive morphology Flowers Florets
Florets ± 40, all tubular, hermaphrodite; corolla yellow, glabrous, 10.5–11 mm long, lobes narrow, 4.5–5.5 mm long.
Morphology Reproductive morphology Fruits
Achenes 3 mm long, densely hirsute with long ascending white or tawny hairs; pappus of numerous plumose bristles, the outer shorter, the inner longer, subequal, 9.5–10 mm long.
