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 Spring 2015 session. Meetings are Fridays at noon during the academic year — all are welcome.
Registration for the 2015 Jepson Workshops is now open!
Group Volunteer Saturday dates are posted for the 2014-2015 session.

Richard G. Beidleman
June 3, 1923 — August 7, 2014
We are mourning the loss of Research Associate Dick Beidleman, who was a devoted archivist and workshop instructor. Dr. Beidleman taught at the University of Colorado, Colorado State University, and Colorado College. He co-authored Plants of Rocky Mountain National Park, and his most recent book was California's Frontier Naturalists (University of California Press). We will miss his warmth, wisdom, and humor. Read his obituary in the Pacific Grove Cedar Street Times.
Alan Smith receiving the Asa Gray Award

Alan Smith was awarded the prestigious Asa Gray Award by the American Society of Plant Taxonomists at its July 2014 annual meeting, "for outstanding accomplishments pertinent to the goals of the Society." Dr. Smith has been curator of ferns in the University Herbarium at UC Berkeley for his whole career and was lauded for both his outstanding contributions to fern floristics and phylogenetic systematics, as well as for developing one of the most important and well-curated fern herbaria in the world. ...

Dr. Paul Silva

Paul Claude Silva
October 31 1922 — June 12 2014
Curator of Algae, University Herbarium, University of California, Berkeley
Phycology, biological nomenclature, the California flora, UC/JEPS, and numerous political, social, and cultural causes lost a devoted friend when Paul Silva died after a several-year illness. Paul's diligence and enthusiasm have affected all of us. We will feel his loss for a long time to come.

New NSF grant to study California plant biodiversity and endemism in a phylogenetic context, received by Brent Mishler, Bruce Baldwin, and David Ackerly, will apply novel phylogenetic methods to better understand the distribution of plant diversity across both space and time in California. This new project takes advantage of the rapidly expanding Consortium of California Herbaria, the constantly updated Jepson eFlora for California, and the wealth of phylogenetic studies that have accumulated. A comprehensive phylogeny for California plants will be built, in part using newly generated molecular data generated from fresh material gathered via an innovative collaboration with citizen scientists from the California Native Plant Society.

A new eFlora project on California Seaweeds has been funded by a three year grant from the Packard Foundation to UC Curator of Algae Kathy Ann Miller and Director Brent Mishler. This online flora will update Abbott & Hollenberg's Marine Algae of California (1976) and provide a portal for students, ecologists, managers, and the public who wish to learn more about our 750 seaweed species. ...

The 2014 SO BE FREE foray was held March 28-31, 2014, in the Santa Cruz Mountains approximately 1.5 hours south of San Francisco. More than 50 participants visited a region rich in limestone and marble, as well as marine sandstone deposits, supporting a number of rare endemic bryophytes. Habitats seen included coastal prairie, coast redwood forest, live oak forest, and chaparral scrub.

BERKELEY — Thanks to new molecular-genetic tools and intensive field research, scientists' understanding of the native flora of the Golden State — one of the world's hotspots of botanical diversity — has grown exponentially in the 18 years since publication of The Jepson Manual, the authoritative reference on California botany. New native plants have been discovered, evolutionary relationships redefined, additional species threatened or endangered by development and climate change — .... read more
