Glabrous, fibrous-rooted perennial from a short, woody base, 1.5-4 dm. tall.


Somewhat succulent, the basal ones mostly elliptic-ovate to sub-rotund, abruptly contracted to the truncate base, with rounded teeth and a petiole; cauline leaves reduced and becoming sessile on the upper part of the stem, bluntly toothed or pinnatifid with blunt lobes.


Heads 2-6, rarely more, orange or reddish, rayless; involucre 6-8 mm. high, its bracts generally suffused with reddish-purple.
