9203 Myrtus           Discovered 1993 Oct. 9 by E. W. Elst at the European Southern Observatory.
Named for Myrtaceae, the myrtle family of aromatic trees and shrubs, with more than 100 genera and nearly 4000 species. This family is typical of the Southern Hemisphere, where the Eucalyptus genus is prevalent. Myrtus communis (common myrtle) is a species native to the Mediterranean and is cultivated as far north as England.
