Introduction The Devils Slide Trail begins in Humber Park two miles above the town of Idyllwild at the end of Fern Valley Road. A free wilderness permit is required for day use, and the number of permits is limited on summer weekend days and holidays. The permit is not available at the trailhead, and there are often rangers at the trailhead or along the trail checking permits on heavy use days. We have personally run into rangers checking permits on several different days. The permit can be picked up at the Forest Service office at 54270 Pinecrest, which is just east of SR243 in downtown Idyllwild.
The Devils Slide Trail ends at Saddle Junction, and there are four trails you can take from that point to continue. Guides to three of those trails are here.

Number of Unique Taxa On This Trail
The following histogram gives the number of trails in our database that contain each taxon on this trail. We had 116 trails in our database when this histogram was made; 16 of those trails, including this one, are in this area of San Jacinto Mountain. A number of "1" means the taxon has only been found on this trail among the trails in our database; numbers of "16" or smaller may indicate taxa found only in this area of San Jacinto Mountain.

Fieldwork Dates and Summary of List Changes With Time The following table gives the dates the trail was walked and taxa recorded. After each visit, the table gives the total number of taxa on the list and the breakdown of the taxa without positive identification. See Explanation of Plant Trail Guides to understand the symbols below.

The mileages in the guide are not as good as in other field guides that have been fit to GPS data. The relative mileages here are probably correct to ~0.01-0.02 miles, but the absolute mileages could be in error by ~0.05 miles or so.
The problem is the poor conditions to receive GPS signals caused by dense tree cover and the restricted sky field of view caused by the mountain. For example, I GPS'd every species and every turn in the trail on 7/14/06, but that turned out to be almost useless. Typical errors noted in the field were ~60 feet, and several times the unit lost all satellites. This unfortunately seems typical for GPS tracks here; I compared against previous ones I've made, and they all have significant systematic errors in places. I.e., the problem isn't just the ~0.01 mile claimed accuracy of individual points; there is a bias in the position reconstruction that can be larger than the claimed accuracy.

Comments On Specific Species Pinus ponderosa, P. jeffreyi. These two similar yellow pines are easily discriminated on this trail by the length of the cones and elevation. P. ponderosa has small cones 6.5 to 9.5 cm (2.5 to 3.7 inches) long; P. jeffreyi cones are nearly twice as long, 12.0 to 17.2 cm (4.7 to 6.8 inches).
P. ponderosa is found at the trailhead up to mile 0.25 below an elevation of 6660 feet; most of the specimens in this area are at elevations below this trail. P. jeffreyi is found only on the upper part of the trail, beginning at mile 1.10 at an elevation of 7200 feet; most of the specimens in this area are in Tahquitz Valley above this trail.
See Pinus jeffreyi and P. ponderosa for a map of the distribution of these species on this trail, discussions of the unreliable commonly-used discriminants of these species, and pictures of the cones.
Lessingia filaginifolia var. filaginifolia. These plants key out to Corethrogyne filaginifolia var. glomerata in Munz. Also, some of these plants are unusual in having two-lipped corollas. The usual ligule is spreading, but the other ligule is erect, forming a cylinder around the disk flowers!
Quercus wislizeni var. frutescens. As far as we know, this is the highest elevation specimen of this species, at ~6500 feet. Munz gives an upper elevation of 5000 feet, and the Jepson Manual gives 2000 m = 6500 feet.
Chrysothamnus nauseosus ssp. bernardinus. The first occurrence of this species on trail in 2002 was no longer present in 2003, and has been removed from the guide. It was approximately at the location of the first off-trail specimen at mile 0.53.
Epilobium canum. These plants, like many of the ones we see at high elevations of the San Gabriel Mountains, seem to be hybrids between the two subspecies. See Comments on the Jepson Manual and A Flora of Southern California by Munz: Epilobium canum.
Rhamnus californica. If one takes the taxa in the Jepson Manual seriously, there would be three on this trail:
- Rhamnus californica ssp. californica, with nearly glabrous leaves;
- Rhamnus tomentella ssp. cuspidata, with leaves silvery below with dense stellate hairs between the veins, "dentate to dentate-serrate", with a tip "abruptly narrowed to a point"; and
- Rhamnus tomentella ssp. tomentella, with leaves silvery below with dense stellate hairs between the veins, entire, oblong, with a nearly rounded tip
Clearly, it is crazy to declare that there are three taxa on this trail, and we treat these all as R. californica, without subspecies.
Salix scouleriana. These were keyed out using blooms in April 2004, four plants from the drainage at mile 0.95 and one plant from the drainage at mile 1.23. All plants were males, and are only consistent with a S. scouleriana id from the JM staminate key.
The plants at mile 0.95 show a lot of similarity to Salix lasiolepis. The leaf margins are not uniformly turned down, which is more akin to S. lasiolepis than to the other S. scouleriana on the trail at higher elevation. Many of the leaves, especially on the young whips at the base of the taller trunks, are dead ringers for S. lasiolepis leaves, being elliptic/symmetric and thus very un-Scouler-like.
The plants at higher elevation all have leaves with uniformly-turned down margins, and are clearly all S. scouleriana, with the exception of the single off-trail location of S. lasiolepis at mile 1.28.
Arctostaphylos patula X A. pringlei ssp. drupacea. These specimens caused me great grief for their determination until I finally figured out and proved that these were hybrids of these two species. See Hybrids of Arctostaphylos patula and A. pringlei in the San Jacinto Mountains.
Dead tree with rocks 10 feet off ground near top of tree. Presumably, the ground level has not changed since the tree was alive, since the trunk/root junction is still at ground level. The area has the usual steep slope, so it is highly likely that the slope is the same as it always was, except for the trail construction.
Possible explanations:
- Trail workers threw the rocks there while constructing or maintaining the trail.
- In small rockslides, some rocks hit the trail, which is 3 feet above the base of this tree, and manage to bounce 7 feet into the air to land in the tree stump.
- The rocks fell when there was ~ten feet of snow, making that height the "ground" level during the rock fall. The only slight problem with this hypothesis is that nearly all the rocks in the area are also covered with ~ten feet of snow.
Nick Nixon informs us that this tree is known as the Wishing Tree, and that he knows hikers that make a point of bringing a rock or two to throw at the tree. If the rock catches in the tree, those hikers believe their wish will be granted.
Tom picked up a rock, and lodged it in the tree with his first toss. (;-)
Horkelia clevelandii. The first occurrence on the trail is a single specimen that usually hides under a rock or another plant. The second occurrence at mile 2.04 has bunches of the plants.
Lactuca serriola, Cirsium vulgare. These non-native plants are probably waifs brought in by hikers or horses, and are weeded out when seen.
Eriogonum apiculatum, Nicotiana attenuata, Cryptantha sp.?. These plants were only seen in one year, 2003, with only a single specimen of each, and are possibly waifs brought in by hikers or horses.
Arabis perennans. The plants here have white to pinkish-purple flowers, despite the floras only giving purple to pinkish for the petals. This species is very similar to A. holboellii var. pinetorum, with only one clear difference, which is the separation used in the key in both Munz and the Jepson Manual:
- pedicels spreading at base and recurved ...A. perennans
- pedicels deflexed at base and straight... A. holboelliiAll plants observed in 2004 and 2005 had pedicels that emerged from the stem at precisely 90° and then curved downward.
The floras give only two other distinctions:
- Pedicels gen glabrous (A.p.) vs. pedicels glabrous to pubescent (A.h.), but since this is a "gen" criterion it is impossible to rule out either species with any observation. The pedicels on these plants range from having only a few hairs at most to being pubescent.
- Basal lvs 4-20 mm wide (A.p.) vs. lvs 3-6 mm wide (A.h.) (although the Jepson Manual pix don't show much difference in width, and Munz doesn't give a leaf width for A.h.)
I've seen both species along the Fish Creek Trail in the San Bernardino Mountains. The species differ most noticeably there in their cauline lvs, with A.h. having obvious auriculate lobes at their base, and A.p. having much less noticeable auricles, if any. The plants here look precisely like the A.p. at Fish Creek.
It is interesting that one of the Hall vouchers from his 1902 Flora called A.p. has been annotated to be A.h., and his other voucher is just Arabis sp..
Species that did not bloom in 2003:
Common Name Latin Name Perennial species that were old enough to bloom, but did not bloom Indian milkweed Asclepias eriocarpa Species with all plants too young to bloom in 2003, probably due to the 2001-2002 drought golden yarrow Eriophyllum confertiflorum var. confertiflorum California beeplant Scrophularia californica ssp. floribunda larger mountain monkeyflower Mimulus tilingii hedge-nettle Stachys sp.

We thank Nick Nixon for finding the Pinus coulteri on the trail; Michael Charters for finding the Corallorhiza maculata, taking the picture to help identify the Streptanthus bernardinus, and determining that the Sagina was a perennial, not an annual; an anonymous reader for finding the Cystopteris fragilis; and Jim Adams for sighting the Muhlenbergia rigens off-trail while he was running the trail.
