Many-stemmed perennial, 30-120 cm. Stems sometimes branched, unwinged, floccose-arachnoid. Median cauline leaves semi-amplexicaul, oblong, pinnatifid to pinnatisect, lateral lobes bifid, 2-8-paired, broadly triangular to lanceolate, lateral and terminal lobes with weak to stout 1-24 mm apical spines, spinose-strigose above, with setae 0.3-3.0 mm, otherwise ± glabrous; tomentose below. Lateral branches 0-many, short or elongate, 1-7-capitulate; uppermost leaves 1-6, usually longer than involucre, semi-involucrate or not.
