Erect. Stems unbranched, either solitary or with a few in a cluster. Leaves round to lance-shaped, toothed; basal leaves on long stalks, 2–4 pairs sessile along stem, middle pair often larger than those below.

Grows in moist woods, meadows, along mountain streams, mostly at lower elevations but can be found in high mountains. Highly variable species, generally more leafy than A. cordifolia.
