Count Alexandre Henri Gabriel de Cassini (May 9, 1781 – April 16, 1832) was a French botanist and naturalist, who specialised in the sunflower family (Asteraceae) (then known as family Compositae). He was the youngest of five children of Jacques Dominique, Comte de Cassini, famous for completing the map of France, who had succeeded his father as the director of the Paris Observatory. He was also the great-great-grandson of famous Italian-French astronomer, Giovanni Domenico Cassini, discoverer of Jupiter's Great Red Spot and the Cassini division in Saturn's rings. The genus ''Cassinia'' was named in his honour by the botanist Robert Brown. He named many flowering plants and new genera in the sunflower family (Asteraceae), many of them from North America. He published 65 papers and 11 reviews in the ''() Bulletin des Sciences'' of the Société Philomatique de Paris between 1812 and 1821. In 1825, Cassini placed the North American taxa of ''Prenanthes'' (family Asteraceae, tribe Lactuceae) in a new genus ''Nabalus''. In 1828 he named ''Dugaldia hoopesii'' for the Scottish naturalist Dugald Stewart (1753-1828). Some genera (originally) named by him : * ''Brachyscome'' (1816) * ''Carphephorus'' * ''Dracopis'' Cassini (Coneflower) * ''Emilia'' Cassini (Tasselflower) * ''Eurybia'' (Cassini) S.F.
