Timothy Charles Plowman (November 17, 1944 – January 7, 1989) was an American ethnobotanist best known for his intensive work over the course of 15 years on the genus Erythroxylum in general, and the cultivated coca species in particular.
[2] Plowman joined the Field Museum of Natural History in 1978 where he became tenured in 1983 and was appointed Curator in 1988.
He is one of the main subjects of One River: Explorations and Discoveries in the Amazon Rain Forest by Wade Davis.
[3] The nightshade species Brunfelsia plowmaniana is named after him,[4] as also is the monotypic genus Plowmania.
& Subils is closely related to Brunfelsia, but differs from it most notably in the large and brilliant orange-red flowers (reminiscent of those of the better-known ornamental Ipomoea coccinea) that have earned it well-deserved place in U.S.
