It is endemic to California, where it is an uncommon member of the flora in forests and woodlands.

Description

Orobanche vallicola is a parasite growing attached to the roots of other plants, generally Sambucus species. The plant produces a thick, hairy, glandular pinkish stem up to about 40 centimeters tall.

As a parasite taking its nutrients from a host plant, it lacks leaves and chlorophyll.

The inflorescence is a cluster or branching array of flowers. Each tubular flower is up to 3 centimeters long, yellowish to pinkish and red-veined in color.
