Flora of Northeast Vallecito Mountains and Adjacent Lower Borrego Valley

Panorama of the entrance to the Elephant Tree Area, which is the alluvial fan beyond the gap between the low hills on the left and right. Above the alluvial fan is the main mass of the Vallecito Mountains in the distance. The photograph was taken from Split Mountain Road at the San Diego / Imperial County Line about six miles south of Ocotillo Wells, looking west, on 1 December 2009. The dirt road to the Elephant Tree Discovery Trail is in the foreground.

See also a panorama of six photographs looking north and east from the lower end of Starfish Cove taken on 27 December 2009. The largest green blotches on the hillside in that panorama are Elephant Trees.

Michael Charters' Photo Galleries from 11 March 2010 and 13 February 2010 contain many beautiful photographs from this area.

The Checklist has been updated from all 10 days of fieldwork through 21 February 2013, but the text has not yet been updated. 11 additional species have been included from a survey of a nearby area of the Fish Creek Mountains



This checklist is a start at a true flora of the northeast Vallecito Mountains and the adjacent Lower Borrego Valley.

There are several botanical highlights of the flora here, which we will detail in the future. Perhaps the most interesting is that so far our surveys have not found a single non-native species in Alma Canyon and Alma Wash, nor are there any vouchers of non-native species there. The closest non-native species found so far are along Split Mountain Road near Ocotillo Wells. However, since we haven't botanized this area in prime time, we may yet find a few non-native species.

The Vallecito Mountains are somewhat curiously defined. The Vallecito Mountains, the Pinyon Mountains, and the North Pinyon Mountains form a fairly clear mountainous block, and hence logically should have a single name. But somehow the northwestern part of this block has been given the separate names of the Pinyon Mountains and the North Pinyon Mountains.

As a result, the Vallecito Mountains consist of a northeastern portion and a southern portion. The southern portion of the Vallecito Mountains trends mostly east-west, from Whale Peak on the west to Split Mountain on the east, with Hapaha Flat in the middle.

The northeastern portion is sandwiched between the Pinyon Mountains and Yaqui Ridge to the west, and the Fish Creek Mountains to the east. This northeastern portion trends northwest to southeast, following the fault along the southern edge of Lower Borrego Valley. It includes Sunset Mountain, Harper Canyon, Harper Flat, Starfish Cove, and the Elephant Tree Area.

In this flora, we include the adjacent portion of Lower Borrego Valley south of Old Kane Spring Road and west of Split Mountain Road. The Cactus Garden area at the mouth of Harper Canyon is in this area.

Although we haven't settled on exact boundaries of this area, our current concept is described in words as follows, and shown on the first map below. The northern boundary of this area is Old Kane Spring Road, and the eastern boundary is Split Mountain Road to Split Mountain. The southeastern boundary is roughly along a line from Split Mountain to the southeastern edge of the Mescal Bajada. Southeast of Harper Flat, this southeastern boundary is the same as the boundary used by Gander in his Floristic Regions of San Diego County to separate the Borrego Desert area from the Vallecito Area.

The northeastern boundary will probably be something like the southeastern edge of the Mescal Bajada to the junction of SR78 and Old Kane Spring Road. The area northwest of this northeastern boundary probably is better associated with The Narrows and Mescal Bajada, since that area drains into those regions.

The elevation of this area ranges from the benchmark elevation of 67 feet at Split Mountain Road just north of Halfhill Lake (see second map below) to 3657 feet at Sunset Mountain. Almost the entire area drains to the Lower Borrego Valley and then the Salton Sea via northeast or east-flowing drainages. In this respect, this area is similar to the Extreme Northeast San Diego County area.

The species on this checklist come from three sources:

The floristic area denoted here is plotted in the following large-scale map:

Voucher locations from this area and nearby are plotted as blue diamonds. The northwest group of vouchers come from the Cactus Garden area; the northeast group from the Old Kane Spring / Split Mountain Road area; the extreme southeast group is at Fish Creek near Split Mountain Road; and the southwest group is from the Dave McCain Spring Area northeast of Hapaha Flat. Future revisions of this checklist will probably remove the southwest group, if they are outside our final choice of the floral area boundary.

The vouchers within the rectangle outlined in black are from the Alma Canyon / Alma Wash area from Starfish Cove on the west and the Elephant Tree Area on the east. The rectangle gives the approximate location of the detail map shown below.

Voucher Records

The vouchers come from a search on 29 November 2009 of the Consortium of California Herbaria.

The Consortium records were searched for vouchers with coordinates between 33.027 and 33.126° N. Latitude, and -116.259 and -116.083 E. Longitude. Localities of those vouchers were examined, and additional searches were made to find ones in San Diego County from those localities, including Starfish Cove; Elephant Tree; Kane Springs Road. The detailed localities of those vouchers were examined and ones not definitely in the target area were eliminated. In particular, I eliminated all vouchers whose localities placed them as being along SR78. (A few vouchers plot on SR78 east of Ocotillo Wells, but their localities are Old Kane Springs Road which is probably different.)

339 vouchers were found of 148 taxa. Four collectors were responsible for 243 (72%) of those vouchers:

December 2009 Field Surveys

We compiled separate detailed plant checklists for all species encountered along the four routes shown in the following map:

The approximate location of this detail map is given by the rectangle outlined by black in the large-scale map near the top of this page.

The survey on 1 December 2009 was confined to the alluvial fan / Alma Wash area, and included a small loop near the mouth of Alma Canyon and a larger loop in the middle portion. The total unique mileage surveyed was 4.0 miles. A total of 55 species was found in our 1 December 2009 field survey, of which an amazing 36 (65%) had at least one specimen in bloom. The large number of blooming species was due entirely to a monsoonal thunderstorm on 5 September 2009.

We hiked through roughly, but not exactly, the same route on 9 and 15 December 2009 and found four additional species in this area, for a total of 59 species observed in this area.

The survey on 9 December 2009 covered 0.6 miles above the mouth of Alma Canyon. That survey found a total of 56 species in the Canyon, of which 41 were also found in the 1 December 2009 survey. We hiked through the same route on 15 December 2009 and found two additional species for this area, for a total of 58 species for this section.

The survey on 15 December 2009 covered 0.43 miles above the end point of the 9 December 2009 survey. It found a total of 55 species, including eight species not found in either of the previous two surveys.

The survey on 27 December 2009 covered 1.31 miles above the end point of the 15 December 2009 survey. This was not as thorough a survey as the other surveys, since we spent most of our time just hiking to get to Starfish Cove. Nonetheless, this survey found a total of 57 species.

Eight additional species were found in brief surveys made in two stops also shown on the above map, surveyed briefly on 1 and 9 December 2009.

All surveys together found a total of 94 taxa.

Note that many of the normal winter / spring annuals and perennials are missing from our surveys due to the time of year.

Some of the species we found could not be reliably determined, either because the observed plants were dead (annuals) or were not in bloom and showing their key characteristics. Two of them are identified only to the genera level in the table below: Cuscuta sp. and Ephedra sp. (2 lv'd). Other taxa that need confirmation from plants in bloom are: Descurainia pinnata ssp. glabra; Eriogonum thomasii; Lupinus arizonicus; and Sphaeralcea ambigua var. ambigua. All of these have vouchers from this area, making these the likely determinations, but one never knows for sure without doing a proper determination.

Perhaps the most amazing thing revealed by our surveys is that we did not find a single non-native species in Alma Canyon and Alma Wash. The only non-native species we found were in our stops along Split Mountain Road.

Number of Species in the Combined Checklist

The combined checklist contains 182 taxa, although two of the vouchered species may not be correctly determined and perhaps three or four additional entries may not represent distinct taxa (see below). Of the 182 taxa, 149 are vouchered, 94 were found in our three December surveys, and 62 are present in Rebman's Checklist. Our surveys found 26 species not vouchered from this area or recorded in Rebman's Checklist, an increase of 17% in the total checklist.

Checklist for Northeast Vallecito Mountains

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 five characters in order to save space in the table rows.

An asterisk before the Common Name indicates a non-native taxon.

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 16 January 2013, 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 go to special pages with more information on those species.

The column #Plants gives a rough estimate of the minimum number of plants that we saw, with a maximum value of 99 plants. The main intent of this column is to indicate the species for which we found very few plants. Separate estimates are given for Alma Canyon (header AC); and for the rest of the area in the Elephant Tree area, as shown on the above map (header (El).

The columns with header #V give the number of vouchers found in this area. In the list below, the vouchers for Glorietta Canyon and Yaqui Meadows were combined to save space, under the header of Gl. The header YP gives the number of vouchers in the Yaqui Pass Area.

The column #V is the number of vouchers for each taxon from the Consortium, with a maximum value of 9. An entry of Rb is a species that appears on the Rebman checklist for Starfish Cove that has no vouchers here.

All Gutierrezia plants in our surveys have been assigned to G. californica. Plants called G. sarothrae here are the same taxon, intermediate between those two species found outside southern California.

We have assigned all Aristida purpurea plants just to the species name.
