Flora of Table Mountain, San Gabriel Mountains
Fig. 1. Two species found in the San Gabriel Mountains only on the carbonate rocks at Table Mountain, or also only in the immediately-adjacent Blue Ridge. Both species are widespread outside of the San Gabriel Mountains.
Left: Gutierrezia microcephala, sticky snakeweed, photo taken by Tom Chester on 23 August 2013 just east of the west summit of Table Mountain. In the San Gabriels, this species is confined to the carbonate rocks at Table Mountain.
Right: Phlox diffusa, spreading phlox, photo taken by Michael Charters on 13 July 2015 just west of the lower parking area on Table Mountain Road. This species is found on the carbonate rocks at Table Mountain, but also has a few localities on the north side of the Blue Ridge immediately south of Table Mountain.

Target Species Found in Nearby Areas
Table Mountain is an unusual place in the San Gabriel Mountains, since it is a high-elevation terrain on the other side of the San Andreas Fault from the rest of the San Gabriel Mountains. Most of the San Gabriel Mountains belongs to the Pacific plate, consisting of highly-fractured plutonic and metamorphic bedrock transported on the southwest side of the San Andreas Fault from roughly the Salton Sea area, over one hundred miles to the southeast of its current location. In contrast, Table Mountain is a piece of the Mojave Desert province of the North American Plate that has been mostly uplifted in place by vertical movement along the San Andreas Fault, making it similar in origin to the northern part of the San Bernardino Mountains that are also on the north side of the San Andreas Fault. In fact, recent evidence shows that the exposed Holcomb Ridge - Table Mountain rocks were formerly south of the same rocks in the western San Bernardino Mountains that are about 17 miles to the east, that were displaced along the Cajon Valley Fault prior to the presence of the San Andreas Fault in this area (see Fig. 5 and stop #A5 in Geology and Hydrology in the Eastern San Gabriel Mountains).
Table Mountain consists of plutonic rocks and gneiss that includes some carbonate rocks that support some plant species not found elsewhere in the San Gabriel Mountains, or have a very limited distribution elsewhere in the San Gabriels (see below).
Table Mountain is in the extreme northeast portion of the San Gabriel Mountains. We define the Table Mountain floristic area extending from Mescal Creek on the west to Sheep Creek on the east, north of the San Andreas Fault in the Wrightwood / Swarthout Valley, and south of the alluvial deposits in the Mojave Desert; see topo map.
This checklist is from six field surveys and from vouchers.
- The first survey was made at a non-optimal time of year on 23 August 2013 by Adrienne Ballwey, Michael Charters, Tom Chester, James Dillane, RT and Shaun Hawke, and Jane Tirrell. We first surveyed a bit of the area immediately west of the lower parking area on Table Mountain Road. The route was then from the upper parking lot on Table Mountain Road, the Mountain High North Resort (labeled Ski Sunrise on the topo map) parking area, along the road to the JPL Table Mountain Observatory (labeled Smithsonian Observatory on the topo map), and then back 4N21 to the lower parking area.
- The second survey was done at a slightly-more-optimal time, on 13 July 2015 by Nancy Accola, Michael Charters, and Tom Chester, essentially repeating the 23 August 2013 route.
- The third survey was done on 7 August 2015 by Nancy Accola, Michael Charters, Tom Chester and James Dillane. The route was continuing north on 4N21 past the main ridgeline to the east peak (7473') and back via the jeep road.
- The fourth survey was done on 26 August 2015 by Tom Chester, RT Hawke and Shaun Hawke. The route was the trail on the east side of the Table Mountain Campground, then 4N04 to the 6678 foot peak on the north ridge of Table Mountain, and then back through the Campground.
- The fifth survey was done shortly after the fourth survey by RT and Shaun Hawke, continuing west on 4N03 to the westernmost mesa of Table Mountain.
- The sixth survey was done on 1 September 2015 by Tom Chester, RT Hawke, Nancy Accola, James Dillane, and Keir Morse. The route was from the lower parking area along Table Mountain Road east along 4N21 to the access road to the east peak (7473') and then along the trail to the east to a saddle above Wrightwood.
Fig. 2 shows the first four routes that have been surveyed by us (not yet including our last two surveys), along with voucher locations from Dick Swinney. Other vouchers do not have accurate locations, so cannot be reliably plotted on this map. Note that the surveyed and vouchered locations are a very small part of the entire Table Mountain area, and hence this species list is certainly quite incomplete for the entire area. The checklist is much more complete for the upper elevations of Table Mountain, but undoubtedly is still somewhat complete since no surveys have been done at prime time in a good rainfall year.

See Michael Charters' Flowering Plants of Table Mountain for photographs from his field visits there on 7/26/09, 8/23/13, 7/2/15, 7/6/15 and 7/13/15. All species seen by him are also in the checklist below. The Checklist below contains a link to the specific page in Michael Charters' Photo Gallery of Table Mountain for species with a photo in that gallery.
Vouchers were searched for the locality of Table Mountain in Los Angeles and San Bernardino Counties on 20 August 2013. All vouchers appeared to be from Table Mountain itself.
The dominant collector by far was R.G. Swinney, who collected 271 of the 436 vouchers, an amazing 62% of all the vouchers. Without his collections, the flora given on this page would be very incomplete. The second most-prolific collector was R.F. Thorne, who was listed as a collector or co-collector on 76 vouchers, 17% of the total.
Vouchers determined only to the family or genus were rejected. Vouchers determined just to the species were placed within a vouchered subspecies if there was only one.
The checklist contains 233 taxa, 191 of which were observed in our surveys and 142 were vouchered from here.
Previous versions of this checklist contained additiona taxa vouchered from nearby areas (Circle Mountain or Pinyon Ridge above 6000 feet), to make the list more complete for future fieldwork. After a field trip at prime time on 10 June 2016, those additional taxa were deleted from the list so that the checklist would more accurately reflect the flora of Table Mountain itself.
Table Mountain is an unusual place for several reasons:
- There are no lycophytes or ferns recorded from there at all!
- It contains fairly extensive exposures of carbonate rocks, mostly dolomite, and thus contains some species not seen elsewhere in the San Gabriel Mountains, such as Gutierrezia microcephala and Euphorbia lurida, and other species that have only a small number of plants found elsewhere there, such as Phlox diffusa. All of these three species are found more widely outside the San Gabriel Mountains; this just happens to be their only location in the San Gabriel Mountains.
It is often the case that species at the edge of their range are found on unusual soil types where they have a competitive advantage over the typical species in that area; see Kruckeberg 2006, Introduction to California Soils and Plants.
Other species that are mostly or entirely confined to the carbonate rocks here, but which are also found in other locations in the San Gabriel Mountains, are:
- Acmispon procumbens var. procumbens, which is also found in a number of places on the desert edge of the San Gabriel Mountains.
- Astragalus bicristatus, which is also found less abundantly off the carbonate rocks here, and also in the Big Pines - Wrightwood area, the Prairie Fork - Guffy Camp area, and the Ontario Peak area. This species only lives in this area of the San Gabriel Mountains, the eastern part of the San Bernardino Mountains, and a small area near Santa Rosa Mountain.
- Astragalus leucolobus, which is also found less abundantly off the carbonate rocks here, and also in the Big Pines - Wrightwood area. The home of this species is the northeastern San Bernardino Mountains, and it is also found less abundantly in a small area near Santa Rosa Mountain, and a handful of scattered locations on the north and west edges of the Mojave Desert.
- Eremogone macradenia var. arcuifolia, which is also found in the Mt. Gleason - Mt. Pacifico region, the Soledad Canyon - Palmdale region, and the desert edge of the Liebre Mountains.
- Eriogonum microthecum, found only on the carbonate rocks here, which is also found in the Kratka Ridge area, Mt. Baldy peak area, and the Cucamonga Peak area. This is a widespread species in the higher elevation desert areas. Our plants are supposedly var. johnstonii, confined to the eastern San Gabriel Mountains and western San Bernardino Mountains, but every plant we've ever seen has white hairs on the stem, which key them to var. simpsonii.
- Penstemon speciosus, also found off the carbonate rocks here as well from Big Pines to Wrightwood, and very abundantly to the north of the San Gabriel Mountains.
In addition, the only location of Opuntia phaeacantha was on the carbonate rocks on the west peak, but it may just have liked that location, rather than the rocks, since it is found off-carbonate elsewhere in the San Gabriel Mountains.
- We have only found two moist / riparian areas in our surveys so far:
- A single small area just below 4N21 where it crosses the drainage southwest of the east peak, peak 7473.
- A more extensive riparian area on the southeast branch of Jesus Canyon along 4N04.
All the other drainages along our surveys have been dry and devoid of moist-area species.
SnGb Geographic Distribution Maps for Table Mountain Species
Tom was struck by finding a number of species at Table Mountain that he had not seen elsewhere in the San Gabriel Mountains. He began a project to take the species found at Table Mountain, and examine their geographic distribution in the San Gabriel Mountains. This project was begun on 16 September 2015, and is currently quite incomplete. Nonetheless, some of the distribution maps produced are already quite interesting, with a set of species found only on the north edge of the San Gabriel Mountains, and some found only on the northeast edge.
See SnGb Geographic Distribution Maps for Species Found at Table Mountain.
- Two taxa vouchered from nearby areas, Encelia actoni and Eriogonum umbellatum var. subaridum, were not added to the list, since we judged they would at best be found at the base of Table Mountain.
There are a huge number of plants of Eriogonum umbellatum var. munzii present at Table Mountain; it is one of the dominant species, sometimes forming dense fields of plants. Var. subaridum is a distinct shrub, with woody stems at base, found so far by us only in areas also inhabited by Yucca brevifolia in the lower-elevation Sheep Creek area on the east side of Table Mountain. It is possible that var. subaridum accompanies the Yucca brevifolia on the eastern end of Table Mountain above Sheep Creek, but we haven't yet observed var. subaridum at Table Mountain itself.
We note that a number of vouchers determined as Eriogonum umbellatum var. subaridum from areas of the San Gabriels above the Yucca breviolia habitat are actually var. munzii. Vouchers of these two varieties are quite difficult to determine properly, since the key to distinguish them is ambiguous and vouchers rarely are of the entire plant.
- Two vouchered taxa, Lupinus albifrons var. albifrons and Astragalus douglasii var. parishii, were rejected as almost-certain misdeterminations.
- There are probably other taxa in the checklist that are misdeterminations as well, such as Phacelia egena, which we plan on deleting in the next version of the checklist.
The Phacelia plants that are like P. egena and P. imbricata in this area appear to be quite uniform, and are clearly P. imbricata, from the few lobes on the leaves and the cylindric corolla. However, they are not clearly a subspecies of P. imbricata, since they combine traits of ssp. imbricata and ssp. patula.
Heckard, in his marvelous 1960 monograph on this group of Phacelia species, calls them "intergrade group 1", which contains most of the plants at SnGb from 3000 to 7000 feet:In all three groups the narrow calyx lobe is present and is important owing to the association of this character as a regular feature (and key character) of ssp. patula. The plants of group I are largely like those of ssp. imbricata in other characteristics. p. 43.
- A surprisingly large number of duplicate vouchers have different determinations for each set, implying that at least one of the determinations is incorrect. These usually are of taxa which are difficult to separate, or which need more taxonomic work done on them, so care should be taken on any field or specimen identification for these taxa. They are given in Table 1, with the determination as the one on the voucher, not necessarily the 1993 Jepson Manual scientific name given in the Checklist.
In fact, a very interesting project would be to compile all the different duplicate voucher determinations for all southern California species, and make a list of the frequency of occurrence for each species, and the species which is most frequently its counterpart on the duplicate vouchers. That would probably give a pretty good list of pairs of taxa that need further taxonomic work to see if they are actually separate taxa, and if so, how best to separate them.

After this table was produced, Andy Sanders reexamined UCR182477 and found it was actually Gutierrezia microcephala. Hence G. sarothrae was deleted from the checklist.
- Phlox austromontana was deleted from the checklist, since the RSA voucher was annotated by the Phlox expert Carolyn J. Ferguson in 2011. Carolyn also kindly provided us with information about how to best distinguish P. austromontana from P. diffusa, and we confirmed from the single blooming plant on 13 July 2015 that the plants here were indeed P. diffusa. Since the plants are only found here in a 2 mile x 1 mile rectangle, all apparently on limestone habitat, we think it is extremely unlikely that any plants of P. austromontana are present here. See Phlox austromontana and Phlox diffusa for more information.
- Giant sequoia, Sequoiadendron giganteum, has been planted in the Table Mountain Campground, and is not native to this area. In addition, we found a single plant of Gayophytum diffusum ssp. parviflorum along the Campground Road, which may have been brought to this area by campers.
- The common dandelion, Taraxacum officinale, was found only in the parking area for the antenna site on the east 7473' Peak.
See Information about the order in which the species are presented, and the links from the Scientific Name and Common Name.
The column #V gives the number of vouchers for this area, with a maximum of 9 vouchers recorded in that field. If there is no entry in that field, that taxon was vouchered in a nearby area, or, for three species, Fritillaria pinetorum, Linanthus concinnus and Yucca brevifolia, added by RT Hawke from his prior observations at Table Mountain. A symbol of ? before the number indicates whether a species is one of those which have a duplicate voucher with a different determination (see Table 1). The duplicate voucher determination will not have a symbol if we have verified that determination in the field, or if that determination was confirmed by other vouchers.
The column #Pls gives the minimum number of plants, up to a maximum of 99, from all the surveys. If there is uncertainty in the determination, the number has a symbol associated with it, ~ for a probable determination, sp or ? for more uncertain determinations.
The column MC gives a link to the specific page in Michael Charters' Flowering Plants of Table Mountain for species with a photo in that gallery.
