Besseya commemorates Charles E. Bessey, wjhi did collected a few plants in Michigan in the middle 1800's, but is far better known for botany in the west (where, in fact, most of the species of Besseya occur).
This is nested in a broadly construed Veronica, but perhaps in the long run, it may be better to achieve monophyletic genera by splitting Veronica further.
All species found in Besseya
