Characteristics

A rhizomatous perennial herb, stems solitary or 2 to 3 together, erect to ±450 mm, commonly simple, rarely forking, loosely grey-cottony, densely leafy. Radical leaves (seldom represented in herbaria) rosetted, spreading, up to 30 x 10 mm, lanceolate, apex acute to very acute, base broad, half-clasping, both surfaces enveloped in silvery silky, rather 'stringy' indumentum, rarely woolly-felted; cauline leaves similar but smaller (up to 20 x 8 mm), not decreasing in size upwards, erect, closely imbricate. Heads homogamous, cylindric, 3-4 x 1-1.5 mm, very many in congested, roundish, corymbose clusters matted together with wool at the base, these in turn congested (but not matted) in a flattish corymbose cyme 20-50 mm across. Involucral bracts in ±4 series, graded, imbricate, outer brownish, inner tipped bright canary-yellow, about equalling flowers, not radiating, translucent or sub-opaque. Receptacle with pit margins slightly produced. Flowers 5-6, yellow. Achenes not seen, ovaries glabrous. Pappus bristles ±6, tips shortly plumose, bases nude, not cohering. Flowering between February and May, but mainly in March and April.
