Discussion	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.

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).
