Discussion | Erythranthe arenaria is known from a cluster of six counties of the central Sierra Nevada: Fresno, Madera, Mariposa, Merced, Tulare, and Tuolumne. Most plants of Erythranthe arenaria have relatively even-sized cauline leaves, all sessile to proximally subsessile. Plants in the Yosemite area with persistent basal leaves that are short-petiolate, ovate with a cuneate base, and relatively larger than the more distal cauline ones, and possibly related to E. arenaria, have been named M. floribundus var. subulatus. These might be construed as showing the influence of E. geniculata, but that species occurs only at the lower range of elevation of E. arenaria, while plants referable to Mimulus floribundus var. subulatus occur at least to 2300 m and also have the erect habit characteristic of E. arenaria. These variants should be investigated, especially in the Yosemite area where they appear to be relatively common, with the possibility that they indeed represent a distinct entity.

Erythranthe parishii occurs in the southern Sierra Nevada (Kern and Tulare counties), mountain ranges of southern California (five counties), desert mountains (Inyo County), and in Clark and southern Nye counties, Nevada. It is the only annual species of sect. Erythranthe. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
