A bit ectopic -- not listed in the Jepson Manual, or subsequent notes, as being found in the Mojave (Antelope Valley), & nearest herbarium specimens are in the foothills nearby. But pretty sure I've got the ID right -- finally! (Originally mis-ID'ed as Yellowthroat). Looks right, and supposedly the puffy-looking calyx (ring of sepals around base of flower) is distinctive.
If you think this observation is inaccurate, please add an ID, participate in the quality assessment above, or describe the inaccuracy in a comment.
