Discussion

Populations of Diplacus johnstonii occur in Los Angeles, Riverside, San Bernardino, Santa Barbara, and Ventura counties. The populations in northwestern Los Angeles, Santa Barbara, and Ventura counties were noted by D. M. Thompson (2005) to be intermediate between D. constrictus and D. johnstonii.

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.
