Characteristics

Perennial herb; flowering stems 40-450 mm high, lateral, decumbent or erect, simple or forking above, glandular pubescent or woolly, closely leafy. Leaves in 1 to several basal rosettes; blade of basal leaves suborbicular to elliptic-oblong, 20-40(-140) x 15-25(-40) mm, mostly loosely grey-woolly or cobwebby; blade of stem leaves oblong to narrowly ovate, smaller. Heads disciform, campanulate, 15-20 x 25-35 mm, solitary or many-headed, open corymb at tips of branches. Involucral bracts in 9-11 series, graded, loosely imbricate, much exceeding florets, glossy, acute, white tipped rose, crimson or scarlet, or entirely rose-coloured or crimson, radiating, stereome divided. Receptacle epaleate, shortly honeycombed. Flowers: female and disc florets ± 165-520, 20-90 female; corolla of disc florets narrowly funnelshaped, yellow often tipped red; Nov.-May. Fruit with cypsela (and ovary) hairy. Pappus bristles several, barbellate to subplumose in upper part, bases nude, not cohering.
More
Variable, stock woody, with 1-several leaf rosettes, flowering stems decumbent or erect, up to 450 mm long, simple or forking above into a few-to many-headed, very open corymb, glandular-pubescent or woolly, closely leafy. Leaves grey-woolly or cobwebby to glandular-pubescent; radical leaves prostrate, up to 140 mm long; cauline leaves oblong to lanceolate, becoming bracteate. Capitula heterogamous, campanulate, ± 25-35 mm in diam.; involucral bracts in 9-11 series, graded, glossy, white to crimson. Flowers 165-520, yellow often tipped red. Flowering time mainly Jan.-Apr. Pappus of several bristles, bases nude, free. Cypselae 0.75 mm long, barrel-shaped, hairy.
The heads are always ±15-20 mm long, but there is much variation in stature, leaf size and indumentum, number of heads on the flowering stem, and colour of the involucral bracts. Plants with 1-headed stems are common above ±1 200 m, those with many-headed stems from sea-level to ±1 800 m, but there are many exceptions. Plants with pure white bracts have been recorded only below ±600 m and grow mixed with plants with particoloured bracts.
Decumbent or erect perennial herb, 40-450 mm tall. Radical leaves suborbicular to elliptic-oblong, 20-40 (-140) x 15-25(-40) mm, mostly loosely grey-woolly or cobwebby; cauline leaves oblong to lanceolate, smaller. Heads campanulate, 15-20 mm long. Flowers yellow often tipped red; involucral bracts white tipped rose, crimson or scarlet or entirely rose or crimson.
