Discussion

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.

Collinsia parviflora is the closest relative of C. grandiflora and is primarily a plant of moist montane habitats with well-drained, rocky or sandy soil. However, it occurs in a wide range of habitats across its entire range. The species is also the most widespread taxon within Collinsia. Some plants from the western coastal ranges may be difficult to separate from C. grandiflora.

Collinsia parviflora is frequently confused with C. wrightii. The corollas of C. wrightii are distinctly purplish; those of C. parviflora are bright blue. The acute to acuminate sepals of C. parviflora contrast with the blunt, rounded tips of sepals of C. wrightii.
