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.

A southern species of sandy open savanna and prairies, not collected in Michigan since the First Survey gathered it in Kalamazoo and Calhoun Cos. in 1838, although two sheets, dated 1843, in the D. Cooley collection (MSC), but without locality, may have come from Macomb Co. The species is still present in adjacent Lambton Co., Ontario.
The species is hemiparasitic on the roots of a great variety of trees and presumably other plants, but can mature without a parasitic attachment. The corolla is purplish to blue and nearly regular.
