Survey of PCT from Cedar Spring Trail to Hwy 74.
This is an extremely rare plant for this area, only discovered in 2012 by Kirk Anderson. The population consists of only a handful of plants in one location. It is a west facing site with gravelly/sandy soil, immediately adjacent to the PCT. The plant in these photos was the largest and most floriferous that we observed.

If this is C. munzii this individual is outside the range of the species. Near homes of North shore, possibly established from humans.

A very large moth that mostly comes in the evenings to feed on the nectar of native plants in the mojave desert. Can be quite easily confused with a hummingbird.

This snake was found upside down on the road after being hit. I rescued it and nursed it back to life. This kingsnake now gives educational talks. :)

I nearly fell over backwards when Don Rideout and I saw these E. nauseosa oreophila plants along the road here!
This species is unknown from San Diego County except at Descanso Junction, where it may have been introduced by Caltrans.
These plants may also be a road introduction. We only found something like six plants, four on one side of the road and two on the other side of the road.
The nearest natural plants known are along SR371 northeast of Anza, and along SR74 down to Pinyon Flat.
On the other hand, this species loves to live along disturbed roadsides, so this might be a natural population. These plants are not unreasonably far from the SR371 / SR74 population, and they are living in a similar habitat at a similar elevation. There are also many plants of this species just across the border in Baja California.
If this is a natural population, there ought to be more plants. Surveying farther east along Lost Valley Road might find more.
Update 23 October 2023: Carla Hoegen and Fred Melgert surveyed farther east on 7 October 2022, and indeed found a number of additional plants.

阿罗约柳 (Salix lasiolepis)觀察者
tchester描述
This determination is by no means 100%. I've never gone back in spring when there are fresh flowers to confirm the id.
It would be great if someone would visit this plant in May or early June, and photograph the ovaries to get the determination for sure. If the ovaries have hairs on them, it is S. scouleriana. If they have no hairs, it is S. lasiolepis.
S. scouleriana is by far the dominant Salix here. Keir Morse's friend Huang-chi asked about the determination of these trees, and I fortunately looked at these trees instead of just answering "S. scouleriana". (:-)
I was shocked when I saw the leaves looked much more like S. lasiolepis than S. scouleriana.
However, the leaves were very soft-silky underneath, which is typical of S. scouleriana (but still possible for S. lasiolepis), and S. scouleriana can have leaves that resemble S. lasiolepis in shape sometimes.
So I said we needed an infl to get the id for sure, and voila, Huang-chi produced some dead infl from these trees.
In the field, the fruit appeared glabrous, confirming S. lasiolepis. But with such old fruit, the hairs might have dropped off. I took a sample to study it further, voucher tchester1759.
observations:
twigs yellow-green, hairy
leaves look like typical S. lasiolepis leaves, elliptic and symmetric about middle (tip to bottom) to narrowly oblanceolate, some with a curve to them along their length. but the underneath sides of the leaves are very soft-hairy to the touch, like s. scouleriana.
petioles 5-7 mm. blades 61 x 13 mm; 62 x 11 mm; 58 x 12 mm. tips mostly acute, but some are obtuse. blade edges are somewhat turned down, but not as much as typical S. scouleriana. top surface shiny and green; bottom surface glaucous.
female catkins 30-40 x ~7 mm in fruit
fl bracts persistent, dark brown, densely hairy, body oblanceolate, rounded at tip, 1.9 x 0.8 mm, hairs extend 1.0 mm above body, hairs white, slightly wavy. the bracts look just like the jm2 illustration for S. lasiolepis.
ovary stalk 2.0-2.1 mm in fr, body 2.2-2.4 mm, style + stigma 0.8-0.9 mm. some styles are as short as 0.4 mm, but i don't know if they were broken off, since there are not stigmas attached.
body is glabrous, but the hairs can be deciduous in age, so it isn't 100% clear if this was their condition when fresh.
Using the Munz key, S. lutea and S. lemmonii are ruled out because their lvs are nearly glabrous underneath, and their lf blades are 1.5-4 cm wide and mostly 3-4 times longer. these leaves fit the Munz key perfectly for S. lasiolepis, of blades 1-2 cm wide and mostly ~5 x as long.
S. lemmonii and S. scouleriana are ruled out if the fruit lack of hairs can be trusted.
S. scouleriana also has leaf edges much more turned down than these leaves, and its flower bract has a different shape in the jm2 illustration.
Only S. lasiolepis fits the above, with just one problem - its styles are supposed to be 0.1-0.6 mm, whereas i definitely have some that are 0.8-0.9 mm. But that is a problem for the only other competing determination of S. scouleriana, too.

1 of 2 Verdin bringing fluff and twigs to their nest. This particular twig was too big, but the bird spend quite a while bonking it against the door trying to fit it through, eventually dropping it, then picking it up and trying again, then dropping it again and flying off in disgust.

Survey of PCT from Cedar Spring Trail to Hwy 74.
We saw a lot of plants that we saw 4 days ago, but we also saw some new ones. This species was a major find by Tom Chester. It grows on limestone outcrops and so is highly restricted.
