Polygala senega A. A. Reznicek

In southern Michigan, in a diversity of forested, swampy, rocky, or even prairie-like habitats, shores and banks; in northern Michigan, on calcareous rocks and gravels in openings and at borders of coniferous forests. Surprisingly spotty in distribution, although locally frequent.

A few collections from the sourthern half of the Lower Peninsula are the more southern Polygala senega var. latifolia Torr. & A. Gray, a generally larger plant with the widest leaves ca.1.4–2.6 mm wide (in our specimens). Typical. P. senega has the widest leaves not more than ca. 1.3 mm wide.
