Flora of Sentenac Canyon / Upper San Felipe Wash, Anza-Borrego Desert State Park
Introduction The checklist was updated from fieldwork on 1/8/13 by Tom Chester, Mike Crouse, Kate Harper and James Dillane; from 1/22/13 by Tom Chester, Kate Harper and James Dillane; from a brief stop on 1/22/13 by Tom Chester, Kate Harper and Adrienne Ballwey; and from a yet briefer stop on 3/1/13 by Tom Chester. Only the checklist was updated; nothing else on this page.
This checklist was compiled for use in the field in surveys here. It consists of vouchers from Sentenac Canyon and Upper San Felipe Wash, as well as species recorded in Plum and Grapevine Canyons. Those species were included because the voucher checklist was missing a number of species expected to be found in Sentenac Canyon and Upper San Felipe Wash.
Vouchers were compiled from searchs of the Consortium of California Herbaria on 11 December 2012 and 4 January 2013. The voucher search on 11 December 2012 was done for the Plum Canyon Checklist. The localities of vouchers rejected from the Plum Canyon area were searched for ones in Sentenac Canyon or in Upper San Felipe Wash. The search of 4 January 2013 was using coordinates, for the rectangular box from 33.13 to 33.14° north latitude and -116.44 to -116.41° east longitude.
Duplicate vouchers were removed, and the localities were reviewed manually to remove ones not in Sentenac Canyon or Upper San Felipe Wash.
This resulted in a total of 357 vouchers of 188 taxa.
The top collectors in this area are:
# Vouchers Collector 83 W.L. Jepson 41 F. W. Peirson 40 Frank F. Gander 32 Darley F. Howe Peirson collected with Jepson on 20 April 1928, but also collected on his own on 24 March 1928.
The checklist includes 22 vouchers from Jepson on 24 April 1920 that were probably collected in Plum Canyon, not in Sentenac Canyon or Upper San Felipe Wash. After field surveys are done in Sentenac Canyon and Upper San Felipe Wash, it will probably be possible to properly locate Jepson's vouchers. The localities for nearly all of them just say Wagon Wash, which is ambiguous.
The checklist of those 188 taxa were compared to the checklist for Plum and Grapevine Canyons, where it was found that common species such as Cylindropuntia ganderi, Hyptis emoryi, Yucca schidigera, Erodium cicutarium, Hilaria rigida and Brassica tournefortii were missing. In order to make a more complete checklist for surveys here, the species from Plum and Grapevine Canyons are included below.
The resulting checklist has 328 taxa.
Of course, attempts to make the checklist more complete in this way unavoidably result in the checklist including species that are not actually present in Sentenac Canyon and Upper San Felipe Wash. In the future, after field surveys are done here, species found only in Plum and/or Grapevine Canyons will be removed from this list.
Checklist for Sentenac Canyon / Upper San Felipe Wash As mentioned above, because the voucher checklist is almost surely incomplete, I include the Plum Canyon Checklist and the voucher portion of the checklist for Grapevine Canyon.
The Checklist follows the 2012 Jepson Manual Second Edition with only a few exceptions.
The Checklist is sorted first by the eight evolutionary categories (clades) used in the 2012 Second Edition Jepson Manual - lycophytes, ferns, etc., to eudicots and monocots - and then by family and scientific name. The clades are labeled in the Checklist. Note that this changes the order of presentation of the taxa from that of the 1993 First Edition.
The family name is abbreviated to the first six characters in order to save space in the table rows.
An asterisk before the Common Name indicates a non-native taxon.
The column labeled #V gives the number of vouchers in Sentenac Canyon / Upper San Felipe Wash. If that column is blank, the taxon was from either the Plum or Grapevine Canyon checklists.
The scientific name is linked to the latest online Jepson Manual description for each species, which also gives the months in which each species flowers. That link also gives a map of where the species occurs in California; a plot of elevation vs. latitude for California; and a histogram of the voucher collections by month.
A few species may not have working links, if their names have been updated more recently (such as Mimulus diffusus, which is still listed under M. palmeri in the online flora), or if they are reserved-judgment taxa which are listed in the entry for another taxon name. Some, but not all, of the problematic Jepson Manual links have all been updated to link to the parent species for the taxa without their own entries. Taxa linked to anything other than the Jepson Manual link for the full scientific name used below have been indicated with a ^ after the scientific name, and are discussed here.
The common name for most species in the checklist is linked to Calphotos to give pictures of most taxa. Of course, there is no guarantee that the Calphotos pictures are correctly identified.
Note that the link will not always return pictures, since not every species has pictures at Calphotos, and a number of species still have their Calphotos pictures under the Jepson Manual First Edition Names. Some links have been made to the Calphotos pictures using the First Edition Jepson Manual name, if there are no pictures under the Second Edition name. Of course, that may result in a link with no pictures if those the names of those Calphotos pix are updated in the future to the Second Edition names.
Note also that the links below will return only the specified taxon at Calphotos, and not any subtaxa; i.e., a link to Cryptantha barbigera will not return photos of Cryptantha barbigera var. barbigera. There may be additional pictures at Calphotos under a different scientific name such as the First Edition Jepson Manual name.
Some links, such as for Bochera perennans, go to special pages with more information on those species.
Some of the picture links have been updated to link to a page that has pictures. Taxa linked to anything other than the Calphotos page of their full scientific name used below have been indicated with a ^ after the common name.
If you find any links from either the scientific or common names below that do not work, please let us know so we can update them.
