Oenothera glazioviana R. W. Smith

A taxon apparently of garden origin, collected in sod along a roadside at Cedar Springs, Kent Co., in 1895 (C. W. Fallass 813, ALBC, MSC); the Clinton Co. record is from a yard at Bath in 1880 (L. H. Bailey, BH) and may have been a cultivated plant.

Easily recognized by its very large flowers (petals ca. 4–4.5 cm long on our specimens), the leaves undulate when fresh, and the stigmas elevated above the anthers at anthesis.
