9316 Rhamnus           Discovered 1988 Aug. 12 by E. W. Elst at Haute Provence.
Named for Rhamnaceae, the buckthorn family of deciduous and evergreen trees, shrubs and climbing plants, with 60 genera and around 900 species. They grow wild in all parts of the world. Some of the species yield dyes. The berrylike fruits appear in dense clusters. Rhamnus purshina (bearwood) produces a dry bark (cascara sagrada) that is used as a laxative.
