Discussion

Collinsia concolor grows in dry habitats of the Peninsular Ranges. Flowers in tiers of dense whorls with bluish-tinged (or blue-blotched) corollas, a triangular region of purple spots in the adaxial lip, and lack of curved appendages at the bases of the filaments are unique to it. It is frequently confused with C. heterophylla because of morphological similarity and range overlap.

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.
