Calaway Homer Dodson (born December 17, 1928) is an American botanist, orchidologist, and taxonomist.


Dodson was born in Selma, California.[1] He specialized in orchidology very early in his career. Over the course of his life, he made numerous expeditions to the tropics of the Americas, covering the Andes of Colombia, Ecuador, Peru, and Bolivia, where he collected specimens and discovered new species of different genera of orchids.

In 1960 Dodson began, in collaboration with Robert Dressler, a classification of the Maxillaria of the Americas. In 1965 he presented a study of the pollinating agents of orchids and the importance that they have on the evolutionary development of the family Orchidaceae.

In the spring of 1973, Dodson was named Executive Director of the new "Marie Selby Botanical Garden" in Sarasota, Florida, of which today he is "Honorary Curator of Orchidaceae".[2] In 1975 Dodson created the genus Dressleria (named after Robert Dressler) including species of the genus Catasetum, from which he also reclassified other species of the genus Clowesia.

After making various publications related to the world of orchids, Dodson now works on a project to compile information of the orchid family into a database, including images and facts from species from across the world. To date, the project has collected information on 57,000 orchids.
