Please try our next iteration of the Michigan Flora Online here. Beginning on February 1, 2023, michiganflora.net 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.

Sandy plains and banks, especially jack pine, oak, and aspen savannas and forests; does well after fire.
Rarely the base of the stem has some scattered long ± straight hairs, though these are less dense than in H. gronovii and H. longipilum. Occasionally a plant will lack the conspicuous and distinctive reddish purple borders on the leaf veins, and a very few plants have the bristly hairs around the margin of the leaves sparse or lacking. The heads are fewer-flowered (not over 25) than in many species. The inflorescence at maturity is very broadly paniculate, with ± divaricate branching. See also comments under H. gronovii, which may have basal leaves of similar shape (although usually not all leaves are basal).
A collection from Schoolcraft County may be a hybrid with Hieracium scabrum.
