Marion Ownbey Herbarium

Type Specimens

In addition to the general collection of specimens, visitors have access to the special collections of type specimens and cultivated plants. The herbarium has a small library that emphasizes floras and identification manuals. Visitors should contact the curatorial assistant (wsherb@wsu.edu) for orientation in the herbarium and information of the proper handling of herbarium specimens.
