An early system of plant taxonomy developed by

Antoine Laurent de Jussieu Antoine Laurent de Jussieu (; 12 April 1748 – 17 September 1836) was a French botanist, notable as the first to publish a natural classification of flowering plants; much of his system remains in use today. His classification was based on an e ...

Michel Adanson Michel Adanson (7 April 17273 August 1806) was an 18th-century French botanist and naturalist who traveled to Senegal to study flora and fauna. He proposed a "natural system" of taxonomy distinct from the binomial system forwarded by Linnaeus. ...

's ''Familles naturelles des plantes'' (1763). While Adanson introduced the concept of families, Jussieu arranged them hierarchically into Divisions, Classes and Orders (equivalent to families), in his seminal ''Genera plantarum''. After the publication of ''Genera plantarum'' Jussieu published many memoirs further developing the description and
