Procedure For Compiling The Checklist The Checklist was compiled from two sources:
- Fieldwork done on 21 December 2012 by Tom Chester, James Dillane and Jim Roberts; and
- Vouchers compiled from a search of the Consortium of California Herbaria on 22 December 2012 by Tom Chester.
The fieldwork on 21 December 2012 was primarily to find traces of the old Wagon Road, with only incidental botanizing.
The fieldwork was used to compile a species list, with a GPS location for at least one occurrence of every species, and to estimate abundances for each observed species. Note that the fieldwork list is extremely incomplete for annuals and perennials, since it was made from field trips at the worst-possible time of year, in late fall, which covered only a small area of the canyon along the main hiking route from SR78 to one of the several saddles at the top. We did not attempt to identify dead annuals except for those whose determinations were unambiguous from their remnants. The abundances for those dead annuals may be severely underestimated.
The fieldwork found 87 distinct taxa.
Vouchers were obtained from three separate searches:

Species Checklist 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 #Pls gives a minimum estimate of the number of plants from the field surveys, up to a maximum of 99 plants. The main intent of this estimate is to indicate the species for which we found very few plants.
The column labeled #V gives the number of vouchers in the Sentenac Canyon area.
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. However, as of 26 December 2012, the 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.
