Identification

This is a 8 to 48 tall, erect forb rising on 1 to 5 stems from a short rhizome.

The stems are somewhat zigzag, bending slightly in opposite directions at each leaf node. This is most noticeable between the upper leaves. They are green and not glaucous.

The stem leaves are alternate, large, broadly ovate, with coarse, sharp teeth along the margin. They have 3 to 8 veins but are not strongly triple-nerved. They gradually taper to a sharp point forming concave indentations along the tip. The base of the leaf blade tapers abruptly to a short, wide leaf stalk. There is a leaf-like or membrane-like extension along both sides of the leaf stalk (winged).

Flower heads appear in small clusters in each leaf axil and in a cluster at the tip of the stem. Each flower head has 3 or 4 ray florets.
