The sugar maple, here flaunting its fall colors, is one of the more than 450 species of trees you can learn to recognize at this site on dendrology, the study of trees. John Seiler, a tree physiologist at Virginia Polytechnic Institute and State University in Blacksburg, says that the site draws a broad audience, from college botany students to curious hikers. Illustrated fact sheets covering the most common species of North America provide distinguishing details of leaf shape, flower structure, and growth form. Find out which trees sprout in your state or use the interactive keys to identify species by their leaves and twigs.
