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.

Mimulus acutidens Greene is heterotypic with the South American M. acutidens Reiche, which is a later homonym. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
