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 callosa occurs primarily on the eastern sides of the southernmost Coast Ranges, Transverse Ranges, and southern Sierra Nevada. A report of this species from Nye County, Nevada (J. T. Kartesz 1987) has not been verified by the author.
