Collinsia torreyi
Collinsia antonina
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.

Collinsia antonina is geographically narrowly endemic, known only from Monterey County. It occurs on scree derived from whitish siliceous shale of the Monterey Formation at the edge of woodlands near the shade of Quercus john-tuckeri. It is morphologically similar to C. parryi, which lacks the coarse white hairs on the inner face of the sepals. DNA studies (B. G. Baldwin et al. 2011) show a more distant relationship between C. antonina and C. parryi than suspected from morphology alone.
