Collinsia greenei
Collinsia linearis
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 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.
