Plymouth State University Herbarium

pshA herbarium is a permanent, catalogued collection of preserved plant specimens. Specimens in herbaria are typically organized taxonomically in tall, airtight, metal cabinets and have many uses:  taxonomic verification,  geographic range estimates, biodiversity estimates, and climate change assessment are just a few!

The herbarium at Plymouth State University contains mostly historic collections by E. J. Hehre and many others. The herbarium currently consists of three full cabinets (Angiosperms) and six half-cabinets (Algae to Gymnosperms!), but will nearly double when two, large collections (recent donations) have been added. The herbarium will be indexed after preliminary digitization and once we’ve found a proper space for it.

If you would like to use the herbarium, please contact Diana Jolles at 603-535-3320 or to arrange a visit or request specimen information. If you are looking for specimens from New England for your work, consider using the Consortium of New England Herbaria (CNH).

We are in the process of specimen inventory. As digitization begins, information about our holdings will be accessible here, but you can also follow us on Twitter @PSHerbarium!
