A common group of plants in the Midwest's natural areas, the oval sedges supply food for wildlife while their roots bind the soil and their vegetation creates habitat. Carex of Illinois and Surrounding States: The Oval Sedges offers a guide to the identification, distribution, and natural history of this diverse group of plants. Focused on the Carex section Cyperoideae, the editors cover Illinois' twenty-five species, every oval sedge in Indiana and Kentucky, and nearly every species in Iowa, Michigan, Missouri, and Wisconsin. A two-step process helps users recognise the notoriously difficult-to-identify plants while illustrations and labelled photographs aid users in evaluating morphological characteristics. The editors also furnish first-ever distribution maps for Illinois' recently described species and varieties, plus up-to-date maps for nearly every other species.
Drawing on the study of thousands of specimens, Carex of Illinois and Surrounding States: The Oval Sedges is an invaluable resource for botanists, ecologists, environmental engineers, and professional and amateur environmentalists interested in a deeper understanding of these essential plants.

"I am deeply impressed. This work will be of interest to botanists at many levels, from those who have just learned to distinguish the major groups of sedges to those who, like myself, have been working on sedges for decades but still appreciate the insights of careful observers. I'm eager to see this book in print, and I know many others will be, as well."
