Flora of the Chicago Region: A Floristic and Ecological Synthesis by Gerould Wilhelm and Laura Rericha (2017)

Completely updated and rewritten, the Flora of the Chicago Region: A Floristic and Ecological Synthesis is rich with new and expanded features in comparison with the 4th edition of the Plants of the Chicago Region by Floyd Swink and Gerould Wilhelm (1994). Also, it has added newly-described species and range updates; morphological descriptions; taxonomic etymology; re-evaluations of many problematic genera; an entirely new section of associate flora and fauna such as bryophytes, lichens, insects, birds, and mammals; in-depth descriptions of our region's habitats, geology, and soils; a re-evaluation of our region's coefficients of conservatism, and original illustrations for every genus.

The Flora is available for purchase from the Indiana Academy of Science and the Morton Arboretum bookstore in Lisle, Illinois.
