American Society of Plant Taxonomists

The American Society of Plant Taxonomists (ASPT) is a botanical organization formed in 1935 to "foster, encourage, and promote education and research in the field of plant taxonomy, to include those areas and fields of study that contribute to and bear upon taxonomy and herbaria", according to its bylaws. It is incorporated in the state of Wyoming, and its office is at the University of Wyoming, Department of Botany.

The ASPT publishes a quarterly botanical journal, Systematic Botany, and the irregular series Systematic Botany Monographs. The society gives annual awards for excellence in Botany. The Society gives the Asa Gray Award for "outstanding accomplishments pertinent to the goals of the Society," and the Peter Raven Award to a botanist who has "made exceptional efforts at outreach to non-scientists."
