Anisocarpus madioides (syn. Madia madioides) is a North American species of flowering plant in the family Asteraceae known by the common name woodland madia.

Description

Anisocarpus madioides is a perennial herb growing up to about 75 centimeters in height, its stem coated in rough hairs and stalked resin glands. The lower leaves are up to 12 centimeters long, oppositely arranged, and fused around the stem at the bases. The upper leaves are much smaller and often alternately arranged. The inflorescence produces several flower heads on long peduncles, each with a rounded involucre of glandular phyllaries. The heads bear yellow ray florets up to a centimeter long and many disc florets. The fruit is an achene a few millimeters long, usually with a small pappus. Flowers bloom April to September.
