Citrus plants
Walter Tennyson Swingle Walter Tennyson Swingle (1871 - 1952) was a renowned botantist and one of the twentieth century's foremost authorities on citrus plants. In 1943, after 50 years of service to the United States Department of Agriculture, he was given a position on the faculty of the University of Miami by President Bowman F. Ashe who was impressed with Swingle?s vision of tropical botany. Swingle was given the title Consultant of Tropical Botany and set up the Plant Research Laboratory in the old Botany building in Coral Gables. At UM, Swingle completed his monograph "The Botany of Citrus and its Relatives of the Orange Subfamily" which remains the premier reference for the taxonomy, morphology, and anatomy of these plants.
