It does. It really does.
Their awesome research is expanding the applied uses and economic utility of Phacelia taxa in agriculture and apiculture.
And what’s that in the foreground? Phacelia viscida!
The new schedule is out for the 2013 year of the Jepson Herbarium Workshops! http://ucjeps.berkeley.edu/workshops/2013/index.html
I am going to be teaching Basic Botany: Mastering the second edition of The Jepson Manual – with two options for workshop dates. One workshop will be offered on Feb 9th and another on Mar 9th. This should be a good early spring and excellent class series that we have developed from the Jepson Manual 101 clinics this year.
Registration is open early online for Friends of the Jepson Herbarium http://ucjeps.berkeley.edu/workshops/2013/regform_2013.html Questions can be directed to our courageous Jepson Workshop Coordinator. Information for past years and for the new 2013 schedule for the Jepson Workshops can be found at http://ucjeps.berkeley.edu/workshops/
The California Botanical Society has online payments available on the updated website! Check it out, there is great stuff for everyone looking to join the epic Society or renew your membership, apply for the Annetta Carter Memorial Fund, order back issues, link over to new issues of Madroño, get information for submitting articles to Madroño, or save the date for the upcoming Centennial Celebration April 12-14, 2013.
I heard a rumor that signed copies of a special issue could be requested [KELCH, D. G., and A. MURDOCK. 2012. Flora of the Carquinez Strait Region, Contra Costa and Solano Counties, California. Madroño 59(2):47-108.]
Online payment is available at http://www.calbotsoc.org/payment.html
Any questions, comments, issues, glitches, or requests can be directed to any of the members of council. Compliments for the updated webpage can be sent to our wonderful webmaster.
Part inspiration from past workshops, and part anticipation for the upcoming year. Share your favorite photos from workshops you have attended with our Jepson Workshop coordinator via email. I think my favorite so far is from the ‘planning’ post. Although I am partial to that Phacelia Friday.
This is a typical scene of botanists starting to scatter across the landscape at a stop from the 2012 White Mountains workshop.
The Times Standard news article includes more information, and is slightly more reassuring about the lack of any listed botanists, population geneticists, agronomists, or plant pathologists in the affiliated faculty and research interests on the institute’s homepage. Humboldt State has a world class herbarium [HSC], and a great botany department, this is a perfect synthesis of facilities for future research opportunities. Difficulties for current access, documentation, permits, regulations – I feel that this is a tremendously positive step toward best practices for scientific research on marijuana. Collecting specimens and growing plants of Cannabis for experimental and systematic studies are going to be incredibly important [voucher specimens are the fundamentals of plant biology], and efforts are needed to a] support field research to document rare populations before they are extirpated, b] study evolutionary relationships using comparative genomics with Humulus, c] understand modern domestication of a plant crop with applied breeding programs, and d] understand gene expression and regulation in chemical synthesis pathways in marijuana. HIIMR should also consider supporting a long term seed bank [okay, achene bank] and clonal germplasm repository for landraces of Cannabis, and possibly partner with Philip Morris to apply results to bring to market a marijuana cigarette.
Also, I am interested in a job when I finish my PhD. I will be in touch.
The project deadline for the Fall 2012 URAP project has been extended until September 7th at 3pm!
A list of the open and extended projects is available here.
Project description available at the Baldwin URAP project page [here] and and at the link through the title below. Information and application available at the UC Berkeley URAP [Undergraduate Research Apprentice Program] website [http://research.berkeley.edu/urap/index.php].
Deadline for this project (only) is extended to Friday, September 7th at 3pm. SPECIAL INSTRUCTIONS: Applicants should enter a URAP application on line. Activate it by submitting paper copy DIRECTLY to the faculty member’s departmental mailbox. Apply as soon as possible because projects may be closed as soon as they are filled. Do not wait until the deadline.
Along with the upcoming Jepson Workshop to the White Mountains, I am also pretty excited to extend the field trip by staying at SNARL. Any UC Reserve is great, but this one has a particular magic for me. I was fortunate to be funded by the UC VESR research grant during my MS thesis and stayed at SNARL for field research – and the phacelias in that area are great – in terms of diversity, historical collections, and ability to grow in the cracks of the parking lot. Trigger came along with me on those trips and enjoyed the sagebrush – but will be on a vacation for this one. Service dogs are working dogs, and get vacation days too.
The Jepson Workshop to the White Mountains is coming up and I am excited to revisit the area again. I had a chance to go on the 2009 Workshop and it was amazing. Of course. There was snow, there were bristlecones, and of course there were phacelias.
Continuing the perennial phacelia binge – here is the entire leaved, mat-forming [hey- compact!] and slightly glandular variety of Phacelia hastata of the Sierra Nevadas [CA and NV]. The hispid hairs are really noticeable on the calyx lobes, and some of the odder populations have lavender corollas – but most have white/cream petals.
Phacelia imbricata is a variable taxon, but can be recognized in the field by the overlapping outer calyx lobe [hence "imbricata"] and the dissected basal leaves. Phacelia imbricata var. imbricata occurs throughout California, with two varieties in southern California. However, intergradations with almost every perennial taxon occur throughout the range. The plants are on exposed slopes and roadsides. Finding plants along the way on summer hikes can be pretty delightful in the Coast Ranges – with the white corollas and yellow-green or grey-green leaves these plants [and Eriodictyon] keep the hydrophyll season going.
Phacelia corymbosa is another lovely perennial phacelia, but is covered with short glandular hairs in contrast to the long stinging hairs of Phacelia nemoralis. There can still be stabby hairs occasionally, so care is always a good idea – on this or any perennial phacelia. The glandular exudate stains newspapers when specimens are pressed, and can cause contact dermatitis. Maybe. The glandular trichomes haven’t been tested in this species – but it seems reasonable [see anything by Gary Reynolds - Reynolds and Rodriguez 1979, Reynolds et al. 1980, Reynolds 1981, Reynolds and Rodriguez 1981a, Reynolds and Rodriguez 1981b, Reynolds et al. 1986, Reynolds and Rodriguez 1986]. I get the itchies.
Corollas are white or fade cream and are readily dehiscent, with the typical long exserted stamens of the perennial phacelia group. Leaves are nicely green, and basal leaves usually dissected or lobed, but distal leaves can be simple and entire. There are usually many flowering stems. Jepson recombined this as a variety, if looking for the taxon in the 1943 flora.
The plants form mats on serpentine slopes or banks, and I found groupings on a riverbank. The previous year['s] accumulated basal leaves mound up underneath the new year’s basal rosette.
