Discussion | Diplacus tricolor occurs in northwestern and south-central Oregon and from there across a disjunction to central California as far as Kern County. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
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.
