Plagiobothrys nothofulvus.

Plagiobothrys: derived from two Greek words plagios, "oblique or placed sideways,"
and bothros, "a pit or scar," hence meaning "hollow at the side," and possibly
referring to the pitted face of the nutlets or the position of the nutlet
attachment scar on P. fulvus, the first known species (ref. genus Plagiobothrys)

nothofulvus: from the Greek notho, a word used to indicate close but
not complete agreement, with an aspect of uncertainty or falseness, and
fulvus, "tawny," so perhaps meaning something like "almost tawny(?)"

Very similar to Cryptantha (status in Bay Area?)
