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 linearis and C. rattanii occupy similar habitats, often growing in rocky soil derived from mafic, volcanic rock. They form a lineage but may not be reciprocally monophyletic (B. G. Baldwin et al. 2011). Other than differences in corolla size and shape, and, possibly, seed morphology, they are extremely similar. Corolla shape (floor of throat angled 45° to 60° from abaxial side of calyx and reflexed portion of adaxial lip length 1.5 to 2 times throat) and smaller corolla size are characteristic of C. linearis. Some plants from this lineage, mostly from Oregon, are difficult to assign to either C. linearis or C. rattanii.

Specimens annotated as Collinsia linearis from British Columbia have not been verified.
