Judd system

A 20th-century system of plant taxonomy, the Judd system (1999-2016) of plant classification was drawn up by the American botanist Walter S. Judd (1951-) and collaborators, partially based on APG schemes.

Note: This is a selected list of the more influential systems. There are many other systems, for instance a review of earlier systems, published by Lindley in his 1853 edition, and Dahlgren (1982). Examples include the works of Scopoli, Batsch and Grisebach.
