Lactuca hirsuta R. W. Smith

Dry ± open ground, including oak-pine savanna on old dunes, clearings among jack pines, sandy bluffs and banks, prairie-like areas.

Our plants are all the glabrous or nearly glabrous phase of this species, which, however, is sometimes hairy on the lower internodes. This is a very local species, and most records from the southern half of the Lower Peninsula are quite old.
