Diplacus graniticola
Diplacus grandiflorus
Diplacus graniticola occurs in the Sierra Nevada from Tuolumne County to northern Tulare County. These plants previously were identified within D. layneae, with which they are partially sympatric; where these two occur together, D. layneae often grows in granite-derived sand and gravel immediately adjacent to the granite rock habitat of D. graniticola.

Diplacus grandiflorus (central Sierran) and D. linearis (coastal) are remarkably similar; it seems likely that they are vicariants. Leaves of D. linearis are narrower, and the nodes tend to be considerably more crowded. Corollas of D. linearis have narrower limbs, and both pairs of anthers and the stigma are at the same level and relatively deeply included. In D. grandiflorus, the anther pairs are separated, and the stigma is above the distal anther pair at or near the throat opening.
