Sandy roadside cut bank, with scattered big Ponderosa Pine, cf. Pseudotsuga, and Arctostaphylus above; with Antennaria, Pteridium, Spiraea, and grasses; growing in the sand, or wedged under a rock. Locally common?; ID tentative; spores well-formed; pinna quite densely scaly beneath, and scales present adaxially, too (but sparse); indusia are entire (wavy, but not ciliate); the two plants collected here (Carl Rothfels 4522 and 4523) differed in leaf dissection; I didn't survey the other plants in the vicinity to see what their dissection was like; I was surprised to find Polystichum here, having just had a really hot sweaty hike up the Beverly Turnpike Trail to find them on serpentine (and it took some searching - see Carl Rothfels 4511 and 4513); sample silica-dried, from this plant.
