Characteristics

Perennial herb, stock stout, crowned with one or several leaf rosettes, flowering stems several, lateral to each rosette, 80-600 mm long, often decumbent at the base or ascending, commonly simple, sometimes forking once or twice near the base, more rarely near the apex, densely leafy. Radical leaves up to 120 x 15 mm, but often less than half that, lingulate, oblong or elliptic, apex obtuse or subacute, base broad, clasping, both surfaces clothed in very close, silvery silky-felted indumentum, occasionally more woolly than silky; cauline leaves similar but smaller and decreasing rapidly in size upwards, spreading or more or less imbricate, enveloped in the same silvery, skin-like indumentum as the radical leaves and the stem. Heads homogamous, narrowly cylindric, 2.5-3.5 x 1.5-2 mm, very many in small corymbose clusters congested in a flattened spreading cymose corymb ±20-40 mm across, the whole matted together below with closely interwoven wool. Involucral bracts in 3-4 series, subequal, loosely imbricate, outer brown or straw-coloured, inner tipped bright canary yellow, about equalling the flowers, not radiating, translucent. Receptacle shortly honeycombed. Flowers 4-13, yellow. Achenes 0.75 mm long, narrow, glabrous. Pappus bristles ±5-7, delicate, tips shortly plumose, bases nude, not cohering.
