Discussion

Collinsia corymbosa is known from Mendocino County. Specimens from other sites identified as C. corymbosa are C. bartsiifolia var. hirsuta. A phylogenetic study using DNA showed evidence of a close relationship between C. corymbosa and C. bartsiifolia (B. G. Baldwin et al. 2011).

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.
