SDSU Herbarium

   The SDSU Herbarium (acronym SDSU in Index Herbariorum) is a teaching and research collection of over 17,500 plant herbarium specimens. These specimens function as research vouchers and are used in teaching Economic Botany (Biology 460), Plant Systematics (Biology 530), and Taxonomy of California Plants (Biology 531) at SDSU.

Our plant collections are mostly from southern California, but also from central and northern regions of the state, Baja California, Mexico, and some southwestern U.S. regions. We have regional collections of Point Loma, Camp Pendleton, Santa Margarita Ecological Reserve and also maintain some research collections from Australia and some southern Pacific islands. The collection is entirely databased. We will be submitting data of the California specimens for accessing and mapping on The Jepson Interchange by early 2008. For further information about the herbarium collection, please contact the curator, Dr. Michael G. Simpson, or the assistant curator, Matt Guilliams.
