TEMPORARILY CLOSED while we relocate

The Department of Botany and Plant Pathology and the Oregon State University Herbarium are relocating this summer to the Research Way Laboratory Building for two years while Cordley Hall is renovated.  The OSU Herbarium is currently closed for packing and moving. We anticipate that the OSU Herbarium will be fully accessible again by October 1. Please delay shipments to the herbarium until that time, when our new address will be available for use. 

OSU Herbarium

The Oregon State University Herbarium 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.

Oregon State University Herbarium

Oregon State University's Herbarium supports learning, discovery, and engagement by obtaining and curating our state’s most comprehensive collection of plants, fungi, lichens, and algae from around the world, with a geographic emphasis on Oregon and the Pacific Northwest. Our resources are used at OSU, across Oregon, nationally, and globally to create knowledge and solve problems. Curation and research in the collection fosters leadership and science-based expertise in our students, preparing them for service in natural resource and data management positions worldwide. We enrich communities across Oregon through our plant identification services, outreach and training sessions, and through our partnership with OregonFlora.
