Annual or short-lived perennial and lactiferous herb with short, spreading, or ascending, naked and scapose stems. Leaves are mostly basal, spatulate-oblong, shallowly to deeply irregularly dentate or pinnately lobed, with sharply incised lobes pointing toward the base and margins covered with small (<1 mm) cartilaginous denticulations. Heads are subspherical, borne sessile or on short peduncles, arranged in axillary or terminal clusters on long scapes, with yellow ligules. Fruits are truncate, spongy, compressed and ribbed, with 6 mm-long pappus achenes, most of them having lateral ribs forming prominent wings.
