Heads up: Some or all of the identifications affected by this split may have been replaced with identifications of Erythranthe. This happens when we can't automatically assign an identification to one of the output taxa. Review identifications of Erythranthe lewisii 542522

Taxonomic Split 39598 (Committed on 2018-10-03)

POWO supports (http://plantsoftheworldonline.org/taxon/urn:lsid:ipni.org:names:77139998-1) the split into E. lewisii sensu stricto and E. erubescens described by Nesom 2014: http://www.phytoneuron.net/2014Phytoneuron/31PhytoN-sectErythranthe.pdf.

To summarize, the pink Sierran flowers formerly called E. lewisii are now E. erubescens, and the deeper pink / purple flowers in the Cascades and Rockies are still E. lewisii. There should not be much geographic overlap with the possible exception of Shasta County, CA.

@ajwright and @grnleaf, can you take a look at this and tell me if I got the atlases right?

The atlases look faithful to Nesom. He doesn't mention Inyo Co, CA, or Washoe and Storey counties, NV... Of those three, only Washoe Co seems to have observations here. It would be reasonable to assume that if a pink Erythranthe were there, it would be E. erubescens, and presence in Inyo Co, at least, seems certain along the Sierran crest.

Thanks. Also, since E. erubescens does not really have a common name yet, I took the liberty of conducting a poll of California Native Plant Society Facebook users to choose one, and the winner was "Blushing Monkeyflower": https://www.facebook.com/groups/38417209275/permalink/10157119792859276/

I like it, even though I'm generally against coining names - in my experience, they encourage people to not bother with the Latin, and even to deride it as superfluous. (It would be interesting to see in a statistical sense whether people are more likely to scale the wall of using the scientific terminology when it's 1) presented up front or 2) presented later.)

There's a distribution map for E. erubescens and E. lewisii on page 3 of: Nesom, G.L. 2014. Taxonomy of Erythranthe sect. Erythranthe (Phrymaceae). Phytoneuron 2014-31: 1–41. Published 4 March 2014, which is available here: http://www.phytoneuron.net/2014Phytoneuron/31PhytoN-sectErythranthe.pdf
Also a key on p. 8 and discussion on pp. 10-14.

Yup, that's the map I used to make the atlases that allow this split to work without bumping everything up to genus.
