Covers the notoriously difficult to identify Cyperaceae with illustrations of all species in the group, emphasizing its great ecological importance. With extensive information on the more than 460 species of Carex, this third volume out of five covering the monocots of North America also includes 96 species of Cyperus, 68 species of Rhynchospora, 66 species of Eleocharis, and the monotypic, North American endemic Cymophyllus. The treatments all contain identification keys, summaries of habitats and geographic ranges, distribution maps, pertinent synonymies, descriptions, chromosome numbers, and phenological information.
"This volume is such an important and useful contribution to the study of Cyperology that it is bound to have a permanent place on my desk." -- Clare Archer, Principal Scientist, National Herbarium, Pretoria, South Africa
