Notes: FNA19: "Leontodon autumnalis is recognized by the usually branched stems with (1)2-5 heads, peduncles bracteate proximal to heads, non-beaked cypselae, and pappi wholly of plumose bristles. It is now established in eastern North America and is sporadic in the west. Specimens with coarsely hirsute phyllaries have been recognized as var. pratensis; intermediates occur and the characteristic does not seem to correlate with other characters."
