How to Identify Plants

First issued in 1957 by Swallow Press, this classic guide to the art of plant identification is now familiar to an entire generation of students. Harrington who was Professor of Botany and Curator of the Herbarium at Colorado State University, gives step-by-step instructions and definitions to help readers recognize and classify plants. The new printing has been reset and reformatted, and L.W. Durrell’s drawings and glossary—more than 500 images—have been digitally enhanced for clarity.

Harold David (H. D.) Harrington (1903–1981) was a professor of botany and curator of the Colorado State University Herbarium for twenty-five years beginning in 1943. Many of his books are still regarded as the definitive sources for their subjects.
