Bases of jumbled small boulders on vegetated talus slope; with Lupinus, at least three species of Eriogonum, Phlox, scattered large cf. Pseudotsuga, Ipomopsis, cf. Lomatium, Achillea, Lewisia, cf. Thlaspi (Carl J. Rothfels 4520), etc; serpentine area. Locally common as dense tufts of leaves from rhizomes wedged under rocks; I didn't get a good handle on the Polystichum present - they were seemingly absent from the earlier parts of the trail (aside from the ones I found on the way out, along the access road near its junction with Forest Service Road 9737, and along the Forest Service Road in the immediate vicinity just across the bridge), although Aspidotis was common; perhaps the Polystichum like slightly larger rocks, more of them, and less dirty?; see Carl Rothfels 4511, 4513, 4522, and 4523; sample silica-dried, from this plant; chromosome material fixed, from this plant.
