The Otis Douglas Hyde Herbarium provides free plant identification to the public. To have a plant identified, please bring in a sample of your unknown plant with either flowers or fruits to the herbarium during our open hours. You may also drop off plant samples for identification with the Center for Urban Horticulture reception desk when the herbarium is not open. If your plant sample does not have flowers or fruit, we will still make every effort to identify the plant sample, but may not be able to accurately identify the plant species.

The Hyde Herbarium also provides assistance to the public, students, faculty and staff with plant identification and plant keying. Herbarium staff can assist with identification questions, provide guidance 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. Submitting voucher specimens to the herbarium provides a permanent record of the plant researched. The herbarium will process plant specimens and provide long-term care to voucher specimens, including them in our main collection. For information on collecting and making voucher specimens, please contact the Collections Manager at hydeherb@uw.edu or (206) 685-2589.
