Collinsia antonina
Collinsia greenei
Collinsia antonina is geographically narrowly endemic, known only from Monterey County. It occurs on scree derived from whitish siliceous shale of the Monterey Formation at the edge of woodlands near the shade of Quercus john-tuckeri. It is morphologically similar to C. parryi, which lacks the coarse white hairs on the inner face of the sepals. DNA studies (B. G. Baldwin et al. 2011) show a more distant relationship between C. antonina and C. parryi than suspected from morphology alone.

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.
