ASPT is dedicated to the promotion of research and teaching in taxonomy, systematics, and phylogenetics of vascular and non-vascular plants. Organized in 1935, the Society has over 1,100 members. To further its mission, the Society publishes two journals: Systematic Botany and Systematic Botany Monographs, provides funding for research and travel, and convenes annual scientific meetings.
Systematic Botany is the Society's quarterly international scientific journal, and publishes papers on topics such as taxonomy, systematics, speciation, morphometrics, molecular phylogeny, conservation, biogeography, and methods
Systematic Botany Monographs is a series published of taxonomic revisions and monographs focused on a particular plant group with emphases on species delimitations and accompanying nomenclature, as well as information about morphology, distribution, and phylogeny.
