James L. Reveal was a professor emeritus of botany at the University of Maryland. A graduate of Utah State and Brigham Young Universities, his broad experience in botanical research embraced floristic studies in western North America (including endangered and threatened species), and the examination of historical specimens gathered in temperate North America.
The majority of his work was in association with the Norton-Brown herbarium (MARY) at the University of Maryland. Additional efforts involve the Department of Botany at The Natural History Museum in London, especially work on the John Clayton herbarium. He accomplished extensive work in the Department of Botany at The Academy of Natural History in Philadelphia, especially with the Lewis and Clark herbarium. He has also worked at the Missouri Botanical Garden and the Monte L. Bean Museum of Life Sciences at Brigham Young University. He had also been a research associate at the Smithsonian Institution, the Missouri Botanical Garden, and the Natural History Museum of London.
His list of publications exceeds 375 titles to date. He is a co-author, with Gary E. Moulton and Alfred E. Schuyler, of "The Lewis and Clark collections of vascular plants: Names, types, and comments," Proceedings of the Academy of Natural Sciences of Philadelphia, 149 (1999):1-64.
His numerous contributions to Discovering Lewis & Clark® reflect his special interest in botanical nomenclature, and the history of botanical explorations and discovery.
