James Lauritz Reveal (March 29, 1941 – January 9, 2015) was a U.S. botanist best known for his contributions to the genus Eriogonum and for his work on suprageneric names. His website, at PlantSystematics.org, also presents material on plant taxonomy including the Reveal system. He published extensively on North American flora, was a member of the Angiosperm Phylogeny Group, and was one of the authors of the APG II and APG III classifications. At the time of his death, Reveal was a professor emeritus at the University of Maryland, adjunct professor at Cornell University's Department of Plant Biology and honorary curator at the New York Botanical Garden. Biography Early life and education James Lauritz Reveal was born on March 29, 1941, in Reno, Nevada to Arlene Hadfield Reveal and Jack Lilburn Reveal (1912-1988), a librarian and a forester/botanist, respectively. Reveal attended Utah State University (B.S. 1964, M.S. 1966) and received his Ph.D. from Brigham Young University in 1969. He held a post-doctoral fellowship with the Smithsonian Institution from 1967 to 1969. Career In 1969, Reveal joined the Botany faculty at the University of Maryland, serving as director of the Norton-Brown Herbarium of the University of Maryland between 1979 and 1999. During his tenure, the Norton-Brown Herbarium amassed one of the greatest collections of Polygonaceae subfam. Eriogonoideae in the world. Reveal's research interests included botanical studies in the American West, especially endangered and threatened species. He studied the history of botanical exploration in the New World and botanical nomenclature and taxonomy as well, with much of his research and writing devoted to the Polygonaceae subfamily Eriogonoideae, commonly known as the wild buckwheats. His interest in combining history and botany led to projects on botanical history of colonial Maryland and on the botanical discoveries of the Lewis and Clark Expedition, about which he wrote several books and articles. A prolific collector, author, and speaker, Reveal collected more than 9,000 plant specimens from North America, Central America, and China, and published over 500 papers; he presented more than 100 invited talks. As a member of the Smithsonian Institution's Endangered Species Committee (1974-1982), Reveal was instrumental in attaining the addition of endangered plant species to the original Endangered Species Act. Reveal discovered or identified over fifty plant varieties, most of these discoveries being flowering plants of the American Southwest. In 1968, Reveal identified five new plant varieties at a Nevada nuclear testing site. In
