This is the website of the ODU Herbarium, a curated collection of vascular plants, bryophytes, and algae for use in teaching, research, and public service. Major emphasis is placed on species of the Atlantic Coastal Plain, including the Dismal Swamp and the Blackwater Ecologic Preserve. The ODU herbarium represents the regional flora and is consulted by the Natural Heritage Program of the Commonwealth of Virginia. We have active loan and exchange programs with other herbaria in the U.S. and the world. Among the strengths of the collection are parasitic angiosperms and quillworts. The research collection contains approximately 28,000 mounted specimens, and a smaller teaching collection has approximately 3,000 specimens. The digital collection can be accessed at http://www.sernecportal.org.
