This book brings together a wealth of information on the natural history, ecology, and systematics of North American aquatic flowering plants. Unlike most books on aquatic plants that have a taxonomic focus and are intended primarily for identification, this book provides a comprehensive overview of the biology of major aquatic species by compiling information from numerous sources that lie scattered among the primary literature, herbarium databases, and other reference sources. The book covers more than 1500 species in 472 genera.
