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.

R. W. Smith
Native from Pennsylvania to the Southeast, or perhaps only in North Carolina. Spreading from cultivation to roadsides, bluffs, old farm sites, and such places. First collected in 1884 in Kent Co.
A specimen of Robinia neomexicana A. Gray, a frequently cultivated small tree from the western US, was collected in Houghton Co. in 1976, with the note that it "reproduces well by suckers in Houghton." It is probably not fully established outside of cultivation. It has rose pink flowers, deeper that those of R. viscosa, and lacks both warty glands and stiff, spreading hairs on the branchlets.
