Phacelia corymbosa is a species of phacelia known by the common name serpentine phacelia. It is native to the mountains of southern Oregon and northern California, where it grows in serpentine soils.
It is a perennial herb growing mostly erect to a maximum height near 40 centimeters. It is very glandular and coated in stiff hairs. The lower leaves are up to 15 centimeters long and sometimes divided into smaller leaflets; leaves higher on the plant are smaller and generally undivided. The hairy inflorescence is a coiling cluster of cylindrical white flowers, each about half a centimeter long and with five long protruding stamens.
