This is the first comprehensive account of the native and naturalized ferns, flowering herbs, and woody plants of Kentucky. Ronald L. Jones has compiled detailed identification keys to families, genera, and species. The plant family descriptions contain information on wildlife and human uses, important weeds, poisonous plants, and medicinal herbs, and the species accounts provide scientific and common names, flowering periods, habitat, physiographic distribution, state and federal designations, and wetland ranking. A total of 179 families, 856 genera, and 2,600 species and infraspecific taxa are included. The extensive introduction includes information on a variety of topics, including the history of the flora, vegetation types, and current conservation issues.
