David Stoughton Conant (June 17, 1949, Springfield, Vermont – June 27, 2018) was an American botanist, specializing in the systematics and genetics of tropical tree ferns.[1]
As a professor at Lyndon State College, he taught a variety of different subjects, including botany, genetics, biochemistry, and systematic botany to name a few. Over his 32-year career, he was a recipient of multiple National Science Foundation Grants which enabled him to travel to New Guinea, Borneo, Australia, Central America, Venezuela, and the Caribbean to continue his passionate study of tree ferns. He named several species of tree ferns, including one which he named after his mother and one which he named after his wife.[1]
After retiring from Lyndon State College, Conant started a business doing excavation projects. Later in Barnet, Vermont, he concentrated on working with his wife on their property, where they cleared fields and built a network of roads through wooded areas.[1]
In 1979 he married Aminta Kitfield (honored by the botanical eponym Cyathea amintae). Upon his death he was survived by his widow, three daughters, and four grandchildren.[1]
