In his study of flowering plants, Genera plantarum (1789), Jussieu classified many of the families used today. Prior to him, Linnaeus classified plants into families based on the number of stamens and pistils. This put a lot of unrelated plants together and split some related ones apart. Jussieu classified plants based on a natural system.
