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 greenei occurs on ophiolites, most frequently on soil derived from serpentinite and similarly altered ultramafic rock. Within its range, only C. rattanii occurs on these substrates; C. latifolia, C. parviflora, and C. wrightii are not on highly mafic soil.

The dark, nearly uniformly purple corollas of Collinsia greenei are distinctive, and the crescent-shaped flap of tissue on the adaxial lobes is unique. Other taxa have folds that bulge outward but are neither doubly crested nor crescent-shaped.
