The species vary in morphology. They are annual or perennial herbs growing from a fibrous root system or a taproot. One species has rhizomes with tubers. The plants produce a single stem or up to 50 or more, usually growing erect, reaching a few centimeters to 75 centimeters tall. Most of the leaves are basal, but some stems have leaves higher up. The blades are often linear to lance-shaped, toothed or lobed, and borne on winged petioles. The flower heads are solitary, growing at the top of the stem or on stalks from the leaf axils. They contain up to 60 yellow or orange flowers. The fruit is a hairless, ribbed cypsela, sometimes with a pappus.[2]
