De Jussieu system


An early list of [systems of plant taxonomy|system of plant taxonomy] developed by Antoine Laurent de Jussieu, the de Jussieu System', is of great importance as a starting point for botanical nomenclature at the rank of family, together with Michel Adanson's Familles naturelles des plantes. While Adanson introduced the concept of families, Jussieu arranged them hierarchically into Divisions, Classes and Orders, in his seminal Genera plantarum.
After the publication of Genera plantarum Jussieu published many memoirs further developing the description and circumscription of families. His final system was published posthumously in 1837, a year after his death.
