Jussieu was the first to publish a natural classification of flowering plants, basing his system on a extensive unpublished work by his deceased uncle, the botanist Bernard de Jussieu.

"In his study of flowering plants, Genera plantarum (1789), Jussieu adopted a methodology based on the use of multiple characters to define groups, an idea derived from naturalist Michel Adanson. This was a significant improvement over the "artificial" system of Linnaeus, whose most popular work classified plants into classes and orders based on the number of stamens and pistils. Jussieu did keep Linnaeus' binomial nomenclature, resulting in a work that was far-reaching in its impact; many of the present-day plant families are still attributed to Jussieu. Morton's 1981 History of botanical science counts 76 of Jussieu's families conserved in the ICBN, versus just 11 for Linnaeus, for instance" (Wikipedia article on Antoine Laurent de Jussieu, accessed 3-2020).
