Volunteers collecting for the Hyde Herbarium in the Arboretum

The Hyde Herbarium also assists students, faculty and staff with plant identification and plant keying. Herbarium staff can guide those with questions to appropriate resources and help navigate the collection of herbarium specimens.

Students and researchers are also encouraged to submit voucher specimens from their research to the Hyde Herbarium. Doing so creates a permanent record of the plant researched that becomes part of our main collection. The herbarium will process the plant specimens and provide long-term care to voucher specimens. For information on collecting and making voucher specimens, please contact the Collections Manager at or (206) 685-2589.
