Collinsia antonina
Collinsia parviflora
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.

Collinsia parviflora is the closest relative of C. grandiflora and is primarily a plant of moist montane habitats with well-drained, rocky or sandy soil. However, it occurs in a wide range of habitats across its entire range. The species is also the most widespread taxon within Collinsia. Some plants from the western coastal ranges may be difficult to separate from C. grandiflora.
Collinsia parviflora is frequently confused with C. wrightii. The corollas of C. wrightii are distinctly purplish; those of C. parviflora are bright blue. The acute to acuminate sepals of C. parviflora contrast with the blunt, rounded tips of sepals of C. wrightii.
