Asteraceae and Compositae are synonymous; both names for this family are correct. This volume covers the 75 genera and 276 species of the sunflower family native to or naturalized in Ohio. It includes several types of identification keys for specialists and laypeople; maps showing distribution, abundance, and flowering periods, descriptions of each species and its habitat, and very clear drawings.

The Asteraceae, often referred to as the sunflower family, are one of the largest flowering plant families in the world, containing over 20,000 species. The family reaches its maximum diversity in temperate zone. In Ohio, 75 genera and 276 species are represented in the flora. "The Dicotyledoneae of Ohio" is a comprehensive study of the sunflower family as it is known to exist in the state today. Dr. T. Richard Fisher traveled the state extensively for thirty years in order to observe and study the many species in their habitats as well as specimens represented at the larger herbaria in Ohio. Fisher has constructed keys to aid in the identification of species and provides complete illustrations, ecological habitat descriptions, and distribution maps showing abundance and flowering period. Several alternative types of keys are provided for readers with varying levels of experience. For example, Fisher offers basic descriptive information for the layperson, while the more experienced student can begin at the generic descriptive key. Each species has been fully described and illustrated, with emphasis on detailed identifying features and a discussion of the abundance and ecology of species. T. Richard Fisher is Professor Emeritus of Biology at Bowling Green State University (Ohio). He is the author of "Introduction to Horticulture" and numerous articles.

Providing a taxonomic treatment of some 700 species of the Ohio flora, this book presents descriptions of and commentary on the individual species and covers the families and genera to which they belong. For those families and genera represented by more than one species, Tom S. Cooperrider includes keys for identification by which the related species can be distinguished from one another. He also describes the species' important varieties, forms, and hybrids that occur in Ohio. Both thorough and accurate, this volume will serve as a valuable source of information about a particular group of Ohio plants and as an aid in identifying an unknown specimen. Original illustrations are provided for nearly all native and naturalized species, along with county dot-distribution maps, which Cooperrider constructed by using records from herbarium specimens (some 80,000 in number) that he examined. This book is one of three in the Vascular Flora of Ohio series covering the dicotyledons of Ohio. The series is part of the Ohio Flora Project, which began in 1950 under the leadership of the late E. Lucy Braun and the aegis of The Ohio State University Academy of Science. A detailed description of plant occurrence that makes Ohio's flora one of the best known of any of the fifty states is the result of this enterprise. Tom S. Cooperrider is professor emeritus of biological sciences at Kent State University and a Fellow of the American Association for the Advancement of Science, The Explorers Club, and The Ohio Academy of Science. The 1994 recipient of the Ohio Biological Survey's Osborn Award, he is the author of Vascular Plants of Clinton, Jackson, and Jones Counties, Iowa and Ferns and Other Pteridophytes of Iowa and the editor of Endangered and Threatened Plants of Ohio.
