Collinsia torreyi occurs only in the Sierra Nevada. In flower, it is superficially similar to C. linearis, with linear leaves and similarly colored and shaped flowers. In fruit, differences in the pedicels are distinct: S-shaped in C. torreyi and straight in C. linearis. Their ranges do not overlap.
