Please try our next iteration of the Michigan Flora Online here. Beginning on February 1, 2023, will point to this new site.

The new site offers several benefits over the existing website, including real coordinate mapping, giving a clearer view of the density of documentation as well as more precision about plant distributions and their link to landforms. We will also have the ability to update species pages more regularly, both in terms of new collections and as more existing Michigan specimens are georeferenced. In addition, we have a better photo display, and offer indented keys.

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.
