Through the support of many individuals, NPSO, and OSU Extension, we now have funding to operate at half-capacity through June 2024. We'll continue to seek support to fully fund our program, so we can keep providing our resources. Thank you — your donations are greatly appreciated!

Oregon State University Bryophyte Collection (OSU-B)

The Oregon State University Herbarium (OSC) houses approximately 550,000 vascular plant, bryophyte, algal, and fungal specimens. The collections are worldwide in scope, with a focus on the state of Oregon and the Pacific Northwest of the United States and Canada. Our bryophyte collection also includes the ORE herbarium, and specimens should be cited based on the original herbarium. Square brackets indicate interpreted information not on the original label.
