Francesco Cupani
was an Italian naturalist mainly interested in botany.
In 1692 he became the first Director of the botanic garden at Misilmeri. Here the plants were classified a system taxonomy of binomial nomenclature later made standard by Carl Linnaeus. This work put him in contact with many botanists, for instance Joseph Pitton de Tournefort, Caspar Commelin, William Sherard, James Petiver, Johann Georg Volckamer, Felice Viali and Giovanni Battista Trionfetti. He is credited with cultivating wild sweetpeas and introducing them to the world. A sweetpea variety is named for him.
