Scientific study of Ohio's plant life began in the late eighteenth century, and the first catalog of Ohio's vascular plants was published in 1860. The most recent catalog, published in 1932, has understandably become outdated. Now Tom S. Cooperrider and his co-authors, Barbara K. Andreas, Allison W. Cusick, Guy L Denny, John V. Freudenstein, and John J. Furlow, provide a comprehensive, modern reference covering the Ohio vascular flora. Including two thorough indexes -- one to scientific names, one to common names -- this user-friendly book will be invaluable for conservation and environmental workers in Ohio and surrounding states.
