Clayey alluvium with rock outcrops intermixes with more densly brome-dominated areas in a matrix. Occurs in a vernally moist grassland with a mixture of annual forbs and grasses with a lot of open ground. Plot is 60 m to the SW (215 deg) from the coast-to-crest trail. There is some cattle disturbance and minor gopher disturbance. Some larger black ants present, collecting forb seeds (harvester ants?).
