The OSU Herbarium contains approximately 140,000 specimens, largely from Oklahoma and surrounding states. The oldest specimen dates from 1862, and there are 215 types. Since its establishment in 1920, it has been curated by Ron Tyrl, R. Stratton, H. I. Featherly, and U. T. Waterfall. Its current director is Mark Fishbein, a taxonomist and systematicist. The herbarium also houses a seed/fruit collection, a cryptogamic collection, library of botanical books, and a complete set of topographical maps of the State of Oklahoma.

The OSU Herbarium is part of a statewide database created through grant support by the National Science Foundation; the Environmental Protection Agency; and the Oklahoma Biological Survey. You can search the database and learn more about it by accessing the links below.
