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 concolor grows in dry habitats of the Peninsular Ranges. Flowers in tiers of dense whorls with bluish-tinged (or blue-blotched) corollas, a triangular region of purple spots in the adaxial lip, and lack of curved appendages at the bases of the filaments are unique to it. It is frequently confused with C. heterophylla because of morphological similarity and range overlap.
