Reaching 3-feet tall, this rough-hairy plant can be covered with few or as many as 25–45, rich yellow flower heads. Note the leaves are triangular to heart-shaped, pointed, and on very short stems.

Flower heads to 2 1/2-inches wide (7.5 cm) have 6–8 yellow, petal-like ray flowers, each 3/8–3/4-inch long (9–19 mm), with a single  notch in the tip, and on stems (peduncles) to 6–inches long (15 cm); disk is yellow with protruding dark stamens. The phyllaries beneath the rays are lance-shaped and gradually narrow to a point.


LEAVES: Lower stems opposite, upper leaves alternate. Blades oval to triangular or lance-shaped, 3/4–4-inches long (2–10 cm), by 1/2–2 3/4-inches wide (1.3–7 cm); margins serrated to minutely toothed, surfaces 3-nerved and rough-hairy. Note the leaf stems (petioles) are less than 3/8-inch long (8 mm).
