Discussion

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.

Collinsia callosa occurs primarily on the eastern sides of the southernmost Coast Ranges, Transverse Ranges, and southern Sierra Nevada. A report of this species from Nye County, Nevada (J. T. Kartesz 1987) has not been verified by the author.
