Lysimachia nummularia B. S. Walters

A native of Europe and Asia Minor, established as a weed escaped from cultivation. Its large yellow axillary flowers make it an attractive plant, and its creeping habit withstands mowing, so it thrives in some lawns, cemeteries, and borders of gardens; also found in floodplains and swamps, on stream and river banks as well as moist shores, and in ditches and meadows. First collected by C. K. Dodge in St. Clair Co. in 1888.

This species is sometimes misidentified (when without flowers) as some native genus, such as Chrysosplenium or Mimulus, from which it can easily be distinguished vegetatively by the orange to black glandular dots visible especially as tiny swellings on the undersides of the leaves.
