Field Trips Log
March 2005
------------------------------------------------------------------------------------------------------------------ ------------------------------------------------------------------------------------------------------------------ I drove down toward Cuyamaca and then headed up toward and through
Anza-Borrego State Park, because there was something Tom had told me
about growing near the entrance. First I stopped at Grapevine Canyon
and photographed two species of Caulanthus that were new to me,
Hall's caulanthus (Caulanthus hallii) and Payson's jewelflower
(Caulanthus simulans). At the entrance to Anza-Borrego I stopped
and photographed Muller's oak (Quercus cornelius-mulleri) and
oak gooseberry (Ribes quercetorum), the latter species which
was a new one for me. ------------------------------------------------------------------------------------------------------------------ I hiked into Hagen Canyon and there was an immediately profusion of
goldfields (Lasthenia californica), yellow peppergrass (Lepidium
flavum), fremont phacelia (Phacelia fremontii), and palmer's
monkeyflower (Mimulus palmeri). As I continued up the canyon,
I added scalebud (Anisocoma acaulis), long-beaked streptanthella
(Streptanthella longirostris), and the gilia that Tom would eventually
identify as little gilia (Gilia minor).
There were shrubs (unblooming) that I believe were little-leaved mojave
indigo bush (Psorothamnus arborescens var. minutifolius), and
a beautiful patch of what clearly to me was a Spergularia, but which
one? I sat down and got my book out and it seemed to key to salt marsh
sand spurrey (Spergularia marina).
The problem was that it wasn't on the Red Rock plant list, and seemed
to be mostly a coastal species. I collected a sample which I con- Farther along I found spectacle pod (Dithyrea
californica), thick-leaved phacelia (Phacelia
pachyphylla), tansy phacelia (Phacelia tanacetifolia),
cooper's jewelflower (Caulanthus cooperi) and bigelow's coreopsis
(Coreopsis bigelovii), but the best thing I found today was something
I have looked for in many places and even found a couple of times but
not blooming. It was desert heron's bill (Erodium
texanum), and in full bloom. Now if I could only find the white-flowering
filaree (Erodium macrophyllum), I would have both of the native
Erodiums. ------------------------------------------------------------------------------------------------------------------ The road continues about a mile to the junction of the Ben Overturff Trail which was a trail created by Ben Over-turff in the early part of the twentieth century that people used to get to his lodge at Deer Park. The lodge was popular with weekend hikers and was operated from approximately 1911 to 1945, when Mr. Overturff had to give it up due to ill health. The trail winds through some of the most beautiful undisturbed woodlands in the front range of the San Gabriels, and is a 7-mile roundtrip. Although there were many wild plants growing along the trail, the one that I was fascinated to discover simply because it's one that I don't see that often was tower mustard (Arabis glabra), with its tall erect stalks and tiny four-petalled flowers. I have never been anywhere where there was so much of this species. I walked the foot trail to Deer Park and then returned by way of the
Sawpit Fire Road. I did not see any California tea, but I also did not
see any pitch trefoil, which I was glad about. ------------------------------------------------------------------------------------------------------------------ After taking many pictures of the plectritis (I couldn't tell how well
they were turning out so overcompensated), we we went in search of the
California tea. We both had a very specific memory of the place we had
seen it before and Richard even remembered having seen it in bloom,
so it did not take us long to find it. It is a perennial that grows
from creeping rootstocks, and so tends to spread over wide areas mostly
under shaded areas. It was not in bloom, but its odd-1-pinnate three-leafleted
leaves with broadly lanceolate to ovate leaflets growing close to the
ground gave us its identity without much ambiguity. Its bloom period
is May to June, so we will have to come back in a couple of months to
get pictures of the flowers. ------------------------------------------------------------------------------------------------------------------ In the same area I found in bloom the stunning Cushenbury milkvetch (Astragalus albens), cooper's jewelflower (Caulanthus cooperi), and what I'm pretty sure was Shockley's rock-cress (Arabis shockleyi). ------------------------------------------------------------------------------------------------------------------ I drove up to Red Rock Canyon today to see if I could get some more pictures of the two gilias I saw there last time and collect samples for Tom to identify. Despite the tremendous rains of this year, I don't think that this was the best bloom I have ever seen in Red Rock Canyon, but it certainly was very nice. I stopped at the parking area called Tamarisk Grove located just at the mouth of the canyon in order to search for Charlotte's phacelia (Phacelia nashiana). Tom and I had seen what we were pretty sure was this species down in Anza-Borrego, but it is out of range there. The Jepson Manual describes it as rare and gives its range as the east slope of the Tehachapis. It is on the Red Rock plant list, and a non-botany friend of mine from the Page Museum told me recently that she had seen it there and told me pretty much where she had seen it. So I climbed up the rocky slope from the parking area through desert holly (Atriplex hymenelytra), at least two different species of Chaenactis, some onion that I still haven't identified, yellow frocks (Eriophyllum ambiguum var. paleaceum), chia (Salvia columbariae) and beautiful desert asters (Xylorhiza tortifolia var. tortifolia), and it only took me about a half-hour before I began seeing the characteristic white-spotted blue flowers of the Charlotte's phacelia. There was no doubt about it, it was the same species we had seen in Anza-Borrego Palm Canyon, where it is seriously out of range. Later I went into Hagen Canyon which I think is the best part of Red
Rock floristically, and photographed and collected samples of what Tom
subsequently identified as rosy gilia (Gilia
sinuata) and little gilia (Gilia
minor). There was also lots of Palmer's monkeyflowers (Mimulus
palmeri), brittle spineflower (Chorizanthe brevi- I need to go back up to Red Rock again during the summer or early fall
to try to get a handle on the Atriplexes that are growing in
Hagen Canyon. I'm sure there's both confertifolia and polycarpa,
but I'm not familiar enough with either to be able to identify them
before they set their fruits. And the Red Rock Canyon plant list also
has A. parryi, A. rosea and A. phyllostegia, so
they might be in there too. Unfortunately the former ranger there, Mark
Faull, who had a good deal of expertise with Red Rock flora has retired
and the new rangers apparently don't have any botanical espertise. |
