Sedges of Maine: A Field Guide to Cyperaceae - Matt Arsenault , Glen H. Mittelhauser , Don Cameron , Alison C. Dibble , Arthur Haines , Sally C. Rooney , Jill E. Weber (paperback)

From the jacket: “Sedges are important components of Maine’s biodiversity and natural heritage. Over 25% of sedge species in Maine are of conservation concern, yet sedges are ubiquitous in many habitats across the landscape. Thus, proper identification of all sedge species is an essential component of ecological studies...”
Sedges, “grass-like” members of the Cyperaceae family, are some of the most difficult vascular plants to identify, even for knowledgeable botanists. The team behind this richly illustrated photographic guide are experts in their field, and they bring sedges to the easy(er) grasp of the reader.
A lengthy introduction provides general information about sedges, followed by keys and identification resources to over 200 species and subspecies. The extensive glossary helps immensely with the terminology associated with this group. Each sedge includes a description, distribution and habitat, and key features that distinguish it from lookalikes, as well as numerous photographs. “Sedges of Maine” is an essential tool for natural resource managers and surveyors, but it is also thoroughly useful to naturalists and even folks who just want to know what those grass looking things are in their backyard! This book is applicable not just to Maine, but also the majority of Sedges found in the Northeastern United States and Southern Canada. 712 pages.
