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 ...
(1748 – 1836), the ''de Jussieu System (1789), is of great importance as a starting point of
botanical nomenclature
Botanical nomenclature is the formal, scientific naming of plants. It is related to, but distinct from Alpha taxonomy, taxonomy. Plant taxonomy is concerned with grouping and classifying plants; botanical nomenclature then provides names for the ...
at the rank of
family, together with
Michel Adanson'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
circumscription of families. His final sysyem was published posthumously in 1837, a year after his death.

Further subdivided by the position of the stamens and calyx in reference to the
ovary
The ovary is an organ in the female reproductive system that produces an ovum. When released, this travels down the fallopian tube into the uterus, where it may become fertilized by a sperm. There is an ovary () found on each side of the body. ...
** Hypogyna (Ovary above attachment of floral parts, ie below ovary)
** Perigyna (Ovary surrounded by attachment of floral parts, surrounding it)
** Epigyna (0vary below attachment of floral parts, ie above ovary)
