Discussion

Leontodon hispidus has been reported in eastern North America. It is recognized by the solitary heads, coarsely hispid leaves and peduncles, and pappi with long plumose and short non-plumose bristles. It is often confused with L. saxatilis, in which the pappi of the outermost cypselae are reduced to crowns. Leontodon hirtus Linnaeus has been reported from various locations in North America; the specimens appear to be assignable to L. hispidus Linnaeus.
