Characteristics

Perennial herb, subscapigerous; crown of rootstock densely woolly and covered with remnants of old leaf-bases; stems 1–2, erect, 20–54 cm high, arachnoid-lanate.. Basal leaves sessile, oblanceolate, 5–16 cm long, 0.4–3 cm wide, gradually tapered into a basally slightly expanded and sheathing petioloid base, margins subentire or indistinctly crenate-dentate in distal part, apex shortly acuminate, green and almost glabrous above, green and sparsely villous beneath; stem leaves smaller and becoming progressively smaller up the stem, sessile, oblong-lanceolate, base semi-amplexicaul, apex shortly acuminate.. Capitula radiate, ± 4 in a lax terminal corymb; stalks of the individual capitula woolly; involucre broadly hemispherical, 9–11 mm long, 10–15 mm in diameter, woolly at base; bracts of calyculus ± 10, narrowly lanceolate, 6–7 mm long; phyllaries ± 18–20, lanceolate, 8–12 mm long, laxly villous, shortly bearded at apex.. Ray florets 10–12, yellow, corolla tube 5–6 mm long, strongly pubescent, rays 11–18 mm long, 3.5 mm wide, 10-veined; disc florets deep yellow, corolla 9 mm long, tube slightly expanded above the middle, pubescent at and below the middle, lobes 1–1.5 mm long, triangular.. Achenes 4–5 mm long, shortly hairy; pappus 8 mm long, white.
More
Perennial herb up to c. 75 cm tall, rootstock silky-woolly, old fibrous leaf bases often present as well, roots woolly, flowering stems one or several from the crown, simple below the inflorescence, loosely woolly, glabrescent, leafy in the lower part. Radical leaves very variable in size, (5-)10-40 cm long, about half of this petiolar, blade narrowly to broadly elliptic, 0.5-8 cm wide, apex acute to obtuse', narrowed to a broad petiole-like base, expanded below, half-clasping and there persistently silky-woolly, margins minutely callose-denticulate, both surfaces lightly cobwebby, usually glabrescent, cauline leaves similar but sessile, soon distant and passing into lanceolate-acuminate bracts. Heads radiate, 2-20 corymbosely arranged. Involucre campanulate, bracts (16-)20, (7-)8-10 mm long, thinly woolly to glabrdus, calyculus bracts few, short. Rays (8-)10-13, long and spreading, they and the disc bright yellow. Achenes 4 mm long, cylindric, ribbed, hairy.
