Perennials.  Stems are 1or 2 from a caudex, relatively thin and often flexuous above; entirely glabrous, or pubescent toward the base, then becoming sparsely stipitate-glandular upward.  Stolons are not produced.  Typical height is from 2 to 3 feet.

Inflorescences are open, panicle-like, with few to many widely spreading branches.  Flower heads are few, on long, spreading  peduncles, located mainly at the tips of branches.  Branches and peduncles are glabrous or sparsely covered with minute, stipitate glandular hairs.

Flower heads are ligulate, with 8-30 florets per head.  All florets are bisexual and fertile.  Corollas are yellow.  Involucres are  6-7(-9)  mm high, sparsely covered with minute, stalked glandular hairs.

Basal leaves are typically absent at flowering.  Lower stem leaves, if present, are elliptic, tapering to a winged petiole.  Mid- to upper leaves are often numerous, oblanceolate to elliptic, tapering to a wedge-shaped base, and with sparsely toothed margins; the teeth are short, but evident.

Plants of dry to mesic woods or open woods, roadsides and disturbed ground.  Flowers August to September.  Not native.
