University of Arizona Herbarium

This is not a museum where you would go to browse the collection.
The herbarium features 365, 00 specimens of vascular plants. If you are trying to identify a plant, the herbarium will help you.
The herbarium was started in the 1890s by botanist James W. Tourney.
Admission is free but donations are suggested for consultants who use the plant identification service frequently.
Hours are 8:30 a.m. to 4:30 p.m.: Mondays through Friday.
If you need research help, call ahead so someone is available for assistance. Bring a sample of the plant, including the bloom, if you can.
