From the preface: This book has two principal objectives: 2.) to give information as to what species occur in Ohio and to show by means of maps the distribution of these species; and, 2.) to give to amateurs, students, and fieldworkers in the natural sciences a ready means of identifying woody plants at any season of the year. In addition, data on variation within the species are included, particularly when of geographic significance or when not in accord with the usual "manual" concepts. It has seemed desirable, also, to include some general information concerning economic plants, relationships, and broad geographic distribution of genera and families.
