Welcome to the Herbaria
The University and Jepson Herbaria of the University of California at Berkeley are two collections of pressed plants housed together along with research labs, libraries, and archives. Together the Herbaria hold about 2,200,000 specimens, one of the largest collections in North America.
 •The University Herbarium, established in 1895, holds botanical collections from around the world.
 •The Jepson Herbarium, established in 1950, specializes in the vascular plants of California.
Botany Lunch Seminar schedule has been posted for the Fall 2015 session. Meetings are Fridays at noon during the academic year — all are welcome.
Group Volunteer Saturday dates are posted for the 2015-2016 session.
