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 latifolia occurs on volcanic and metamorphic substrates in northern California and southern Oregon in the Klamath and Cascade ranges, and in the North Coast Ranges of California. Its flowers are nearly identical to those of C. torreyi, which differs in leaf shape: linear in C. torreyi and elliptic to ovate in C. latifolia.
