Discussion

Collinsia parryi is most closely related to C. concolor, which has larger flowers arranged in tiers of whorls; their ranges are largely allopatric. Collinsia parryi occurs most commonly on the drier, leeward sides of the Peninsular and Transverse ranges. B. G. Baldwin et al. (2011) sampled chloroplast DNA, ribosomal DNA, and introns of nuclear-coding DNA and showed that many individuals of C. parryi had zero sequence-divergence from C. concolor. This result suggests a recent diversification of these taxa from an ancestor that was most like C. concolor.

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.
