3 plants near medium berm at the top of a relatively flat old oak prairie in otherwise montane chaparral. Immediate associate plants include Quercus Agrifolia var. Oxyadenia, Arctostaphylos pungeons, Ericameria parishii, non native grasses. Downslope Ceanothus leucodermis/perplexans, Cercocarpus betuloides.

Stand is not in CCH2 records, nor calflora. Near historic borders of closed mining claims, however the valley clearly funnels a substantial amount of water during wet seasons. Historical records may be necessary to determine if this is a relict stand or remenants of settlement.

On 10/3/74 James Griffin vouchered a discovery of Quercus palmeri in the Clear Creek area of San Benito County. At that time this was a new, isolated, northerly station for this unusual species. Griiffin returned about 3 weeks later with his botanist friend and CA oak maven John Tucker, and together they collected a number of additional vouchers. At that time Q. palmeri went by the name Q. dunni (after the remarkable late-1800's naturalist & collector George Dunn, see Jepson's brief bio here). Later Griffin & Tucker published a 1976 Madroño note on the newly discovered station. Motivated by the above, and a prior interest in this species, I was eager to look for these Palmer Oaks...and joined Joyce Gross & Alice Abela to search for them, almost 50 years after Griffin & Tucker's voucher collections.

After planning and walking a route with a number of promising point locations suggested by the Madroño note & voucher labels, we seemed to have struck-out on our "best candidate sites" and were becoming somewhat discouraged. But crossing a creek after the road we were on faded out, Joyce came upon a smaller trail following the SW side of the creek, and within a few hundred feet there were 3 or 4 clumps of Palmer Oaks growing on the steep bank above the trail :-). Note that zooming-in on the iNat inset map above, the observation icon appears to the NE of the trail shown there...but that's an artifact of errors in either my camera's GPS reading, the rendering of the trail on the map, or both. The rough location is correct, but the trail follows the SW side of the creek there...and the Palmer Oaks are rooted along the eroding upper edge of the tall bank just SW of the trail.

Palmer Oak is thought to be a relict species that had a more widespread and continuous distribution in Pleistocene and Pliocene times. Except for a few areas in southern California, northern Baja California, and Arizona (see SEINet map here), nowadays it is usually found in small isolated stands of a few individuals, which are often clonal groupings...and these stands are typically many miles apart (e.g. ten, twenty, or much more!). One particular clonal colony growing high on a granitic summit in the Jurupa Hills of Riverside County, CA has been estimated to be 13,000+ years old in this 2009 paper.

The plants here were growing in 3 or 4 "clumps" of scrub to small tree-like stature — each with one to several small, clustered, multiple trunks. They appeared less clonal in growth form than other Palmer Oak groupings I've seen...but may have been clonal. I have no idea how old these plants currently are, but they may have difficulty persisting for a truly long time into the future at this site — as their roots are being undercut by erosion of the bank above the old jeep road/trail and adjacent creek. This may be exacerbated in part by human impacts...recent motorcycle tracks were apparent, and a large branch had been cut off and was lying by the trail. (Some branches were overhanging the trail...and Palmer Oaks are notoriously rigidly-branched with leaves that are viciously stiff & spine-margined!)

In addition to the Jepson eFlora treatment for Q. palmeri, more info is available on the SEINet page here.

I don't think I've ever seen this many Lupinus truncatus in one area before. Perhaps around three dozen lupines in maybe 25 square meters of land!! The ones pictured were growing in very gravelly, rocky loam near an arroyo.

Of all different shapes and sizes. There appeared to be a correlation between proximity to the arroyo and the size of the plants...Also with substrate (bigger ones were on the gravelly loam while smaller ones with smaller leaflets were on sandier, drier substrate)

Growing right by the western side of the road. A strong candidate for Q. garryana semota x john-tuckeri imo. (EDIT: I suppose most of the "QGS" traits could be Q. lobata as well. Tough to say. The leaf litter, indicating semi-deciduousity, and lobed leaves at the very least indicate some sort of lobed, deciduous parent.)

-QJT is the dominant oak species by far in this region with a minority of Q. agrifolia
-QGS traits: Suckering growth habit/stature, deciduousity, appearance of the leaf litter, lobed leaves and general leaf shape, new leaf shape and growth habit, filamentous bracts, yellow-green color of newer leaves
-QJT traits: spikiness of the lobes, rough/tomentose feeling of the leaves (especially the newer ones), wideness of the leaves, bluish-green color and "dustiness" of the mature leaves, dominant yellow central vein on mature leaves, dominant oak species in the area, material thickness and robustness of the twigs

I don't see any QGS in the vicinity. Since this was by the roadside, it is possible that an acorn got carried down from further up the road by water or human activity, and/or QGS from further north into the mountains pollinated some QJT in the area.
