Perennials.  Sap is milky white.  Colony-forming from rhizomes and stolons.  Colonies are often dense and sometimes extensive.  Typical height is 3 to 7 inches.

Inflorescences consist of one or two flower heads at the top of the stem. Stems are scapose, covered with dense stellate hairs and stalked glandular hairs, as well as long, spreading bristles.

Flower heads are ligulate.  All florets are bisexual and fertile.  Corollas are bright yellow with a red stripe on the lower surface.  Involucres are 7-10 mm high, moderately covered with black, stalked glands and minute stellate hairs.  Peduncles, if present, are short.

Basal leaves (persistent throughout the season) are broadly oblanceolate to obovate, with long bristly hairs above and a dense coating of stellate hairs below (so dense that leaf undersides appear whitish).

Plants of fields, roadsides, lawns.  Flowers May to June.  Not native.
