. patent, oblong or ovato-oblong, acute, hairy,
with the margin sinuato-dentate, at the base attenuated
into a generally short petiole, clothed
with long dense white hairs of a glaucous green :
those of the stem having the lowest one nearly
resembling the radical ones, the superior lanceolate,
entire, sometimes bracteiform.
Flowers in a solitary, in (3 two or three from the same
stem, large, sulphur-coloured.
Involucre composed of subulate, erect scales, the
lower ones imbricated, hairy, the hairs either
naked with the base black and the apices white,

Ach en ia oblong, striated, crowned with a pappus about
equal to it in length.
Receptacle of the flowers nearly plane, dotted.
