Discussion

Collinsia childii occurs principally on shaded, rocky soil. It is most common in the Sierra Nevada and Transverse ranges in the interior of southern California. There are also isolated populations in the South Coast Ranges.

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.
