Carleton, Mark Alfred, 1866-1925

Mark Alfred Carleton was an American botanist and plant pathologist best known for his plant explorations in Russia for the USDA and his introduction of hard red wheats and durum wheats from Russia into the American wheatbelt. Carleton collected botanical specimens in southwest Kansas, southeastern Colorado, Indian Territory (present Oklahoma), No Man’s Land (present Oklahoma Panhandle), and the Texas Panhandle in the summer of 1891. These field trips let to the publication of a descriptive bulletin by the National Herbarium. Carleton also worked with Arthur Spear Hitchcock to research plant rusts, which led to his position at the USDA's Division of Vegetable Physiology and Pathology which later became a part of the Bureau of Plant Industry.
