The inflorescence is coiled in bud, but generally elongates in fruit. The pedicels are generally 0–1 mm, and the flower is bisexual with the sepals fused below the middle.[3]


The genus name, Plagiobothrys, is derived from Greek to mean "sideways pit" and describes the position of nutlet attachment scar.[3]
