(9364) Clusius Main-belt Asteroid
Discovered on 23 April 1992 by E. W. Elst at La Silla.
Named for Carolus Clusius (Charles de l'Escluse; 1526-1609), a Flemish botanist well-known for his catalogue, published in Antwerp in 1576, of fine drawings of more than 200 plants he had studied in southern France, Portugal and Spain. His system of classification proposed the idea of natural families. The Clusiaceae, a family of plants and trees, was named after him. It is said that he introduced the tulip into Holland.Naming citation (19990402/MPCPages.arc), IAU / Minor Planet Center, via NASA/JPL
