Thank you again to everyone who made 2016 a huge success in the herbarium. Here is some important info about the herbarium this quarter:
- The times this quarter are Thursdays 3 – 5 pm and Fridays 12 – 2 pm.
- I now have the ability to pay for metered parking so please let me know if you’d like to use that option.
- Dr. Paul Wilson is guiding us on a moss collecting hike on Feb. 11th and will be talking with us in the herbarium on Feb 10th during the volunteer session.
- Last quarter, we mounted almost 1,000 new specimens. That was really incredible and thank you to everyone who helped manage the large number of students who were in there!
- We also finished cataloging the Herbarium Library, and boy did we find some treasures. We are still in the process of refiling all the books.
- Cathy and Jason are making progress on our lichens and mosses.
- The SLO Voucher Flora Project is still happening and we are chipping away at that. All of our records can be searched here:
- Plants: http://nansh.org/portal/
- Mosses: http://bryophyteportal.org/portal/
- Lichens: http://lichenportal.org/portal/
In other big news, our newest Botany faculty member, Dr. Dena Grossenbacher, has arrived to Cal Poly. She starts this quarter. She studies Mimulus and Clarkia, among other
wonderful plants. I’m sure you will all meet her at some point this quarter.

See also: Volunteer at the Hoover Herbarium
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. Parking permits are required Monday through Thursday, 7:00 am through 10:00 pm; and Friday, 7:00 am through 5:00 pm. You can either buy a $6 day pass, a $4 3-hr pass, park in a metered space, or park off campus and walk in. I can pay for metered parking, but you’ll want to arrange that with me first.
Questions: email Jenn Yost at email@example.com.

Our banquet speaker this year will be Dr. Glen Holstein , Sacramento Chapter Botanist
Glen is Chapter Botanist for the Sacramento Valley Chapter of the California Native Plant Society. He’s a graduate of Cal Poly, San Luis Obispo, with a degree in biology, and from there to botany graduate school at UC Davis. Glen took a few years off to help found the California Natural Diversity Data Base, participate in creation of the Cosumnes, Cold Canyon, Nipomo Dunes, and Carrizo Plains reserves, and to write a chapter on riparian biogeography for Warner & Hendrix’s California Riparian Systems. Following that he finished his botany Ph.D. at Davis with a dissertation on climatic influences on plant physiognomy in world biomes.
As a botanist consultant he saw much of California and its rare plants. He has been a CNPS member continuously since soon after it was founded. Retirement has enabled him to devote much more time to CNPS as Botanist and Council Delegate for the Sacramento Valley Chapter while also serving on several allied conservation organization boards. One of his projects was guest-editing and writing three articles for the 2011 Fremontia issue on California’s prairies and grasslands.
Tickets are $10 per person – You may reserve your spot with credit card or PayPal by clicking the Tickets button, or if you prefer, you may send payment to D. Krause, 2706 Newton Drive, Cambria, CA, 93428. You may print this form to include with your check.

Invasive Species of the Month: Iceplant (Carpobrotus edulis)
Iceplant is a perennial in the Aizoaceae family, native to South Africa and grows in sandy areas on the coast from Eureka to Baja. This succulently leaved plant is overwhelming and carpets the land. I’ve seen outcompete giant Coreopsis and beach spectacle pod. Iceplant competes for nutrients, water, light and space. In very dry places they have long straggling woody stems. The pink or yellow flowers are beautiful and peak in early summer. The leaves root in the soil at the nodes and reproduces by seed. Seeds that passes through an animals gut germinates better.
Iceplant may be pulled and removed–which is the case at Piedras Blancas lighthouse, with spectacular results from the emerged native plant seedbank. Iceplant may be sprayed and the dead matter makes an excellent mulch for native plantings. Frost also kills Iceplant.
According to Cal-IPC iceplant was brought to California in the early 1900’s for stabilizing soil along railroad tracks. It was planted along freeways by Cal Trans until the 1970’s. Now it provides job security for weed warriors.

Carpobrotus edulis or Carpobrotus chilense?
These two species are very similar, and the Jepson descriptions do not fully cover the overlap of features. Generally C. chilense has smaller magenta flowers (3-5 cm diameter) compared to 8-10 cm for C. edulis, which favors yellow flowers, but there is color ‘crossover’. The flower of C. edulis is pedicelled and C. chilense is sessile. The fruit of C. edulis is triangular in cross section, that of C. chilense more rounded and softer.

The photograph above shows a massive carpet of Carpobrotus at Shark Inlet. The bench in the foreground used to be pickleweed marsh until the Paso Robles earthquake caused the sand dunes to press down into the mudflat, squishing the edge of the flat above the high tide line and enabling the iceplant invasion.

O.K…. so we’re not Vermont. However we do have some pretty fall color displays. If you like the gold of aspen, you will see the same colors in our closely related cottonwood stands, both trees belonging to the genus Populus. (more…)
Monarch caterpillar feeding on Asclepias fascicularis
All of our local native milkweeds are perennials, but like a lot of our drought-adapted plants, die back and go dormant during the long late summer and fall drought. Many gardeners, knowing there is a monarch butterfly/ milkweed connection, try to keep the milkweeds green all year, or use non-native milkweeds that stay green. Cal Poly’s Dr. Francis Villablanca has shown that winter breeding by monarchs will take place if green milkweed is available, which would not normally happen in the overwintering populations in SLO County. Nonstop breeding on the same plants can perpetuate the transmission of a devastating parasite called OE, for Ophryocystis elektroscirrha.
Normally, the transmission cycle is broken when milkweeds go dormant. The infection can kill adults as they emerge from their chrysalis, while mildly infected monarchs fly poorly, don’t reproduce normally, and die early. These very sick butterflies can then carry spores of the pathogen into the milkweeds in other gardens or along the entire migration route.
You don’t have to tear out a non-native milkweed if you cut it way back. While the infection issue is much greater for the central USA migration paths, it is critical that we take preventive actions on the coast, especially since we are still determining how bad it actually is in California.
Many thanks to Dr. Villablanca of Cal Poly on putting all of this together.
