Heather Johnson has a new watercolor for us to use on the cover of this issue of Obispoensis. It’s most commonly identified around the central coast as miner’s lettuce (Claytonia (Montia) perfoliata). The situation where a leaf blade base appears to be passed through (perforated) by its stem is said to be perfoliate.read more

The summer has flown. It seems like I was just admiring the blooms on my Clarkia. Now their seeds are in little packages ready for the seed exchange and I am on to watching the blossoms on my many Eriogonums. I am waiting for the seeds to ripen so those can end up in bags for the exchange as well. In between I have been collecting from Chlorogalum, Ceanothus, Sage, Sidalcea, Silene and numerous other plants.read more
Our chapter would like to have a high quality photo of every species in our county, as will be described in Dr. David Keil’s Flora.
We would like as many pictures as possible to be usable both for scientific purposes and for use in digital media, and as such we
would like to be the owners of the photos under copyright.

During the volunteer sessions at the Hoover Herbarium, people can take part in any number of activities. One of our primary responsibilities is mounting new specimens. This involves taking dried and pressed plants and glueing them to paper. When we mount plants, we do it in such a way that those specimens will last for hundreds of years. Each specimen is a physical record of what plants occurred where and when. Without this valuable information we wouldn’t know when a species goes extinct, expands or contracts its range, or where species occur. After mounting, the specimens are databased and geo-referenced. Then they are filed into the main collection. We have over 80,000 specimens at the Hoover Herbarium. We are also working on a SLO Voucher Collection, which will contain one representative specimen for each species in the county. Volunteers look through our specimens and pick the one that should be added to the Voucher Collection. Additionally, we are actively working on our moss and lichen collections. Volunteers can choose what aspects of the work they would like to participate in. Any and everyone is welcome. The Hoover Herbarium is located on the 3rd floor of the Fisher Science Building (33) in rooms 352 and 359.
