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 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).
