Discussion

Erythranthe geniculata is known from an apparently disjunct cluster of populations in Butte, Sutter, and Yuba counties and then from Tuolumne and Stanislaus counties south to Kern County.

Erythranthe geniculata, compared to E. floribunda, has larger, chasmogamous, and allogamous flowers. The anther pairs of E. geniculata are at different levels, and the stigma is slightly above the adaxial anther pair; in E. floribunda both anther pairs and the stigma are at the same level.

Erythranthe arenaria, E. geniculata, and E. norrisii constitute a group of apparently closely related species within sect. Mimulosma endemic along the Sierra Nevada. All have ovate-petiolate leaves (only the basal ones are sometimes ovate in E. arenaria) with pinnate to subpinnate venation. The more widespread E. floribunda, which is part of the above group, also is similar, but all three endemics have larger corollas with the tube exserted at greater length beyond the calyx margin.

The densely, evenly puberulent vestiture of pedicels, calyces, and distal stems usually is diagnostic, especially in combination with the large flowers (corollas and mature calyces) and tall stature. Plants from scattered collections are much shorter than normal but have large corollas and characteristic vestiture.

Erythranthe grandis characteristically occurs in coastal localities from southern California to northern Oregon but also is found in inland localities and habitats near the coast but well away from salt spray.
