Formerly Mimulus scouleri, this is a relatively rare native monkey flower of
tidal marshes and rivers. I found it a few years ago at Julia Butler Hansen
National Wildlife Refuge, but did not ID it correctly at the time. Mark Egger
looked at this observation on iNat and proposed this name, which I think is
correct.
It’s been found on the Trask River, and in several locations on the lower
Columbia, including John Day River, Tenasillahe Island, near Longview (Mark),
and Cathlamet (me), also on the Fraser River near Vancouver, BC.
If you are out in freshwater tidal habitats, look for it. Yellow flowers,
lanceolate leaves reminiscent of E. dentata, but less deeply toothed, more
wavy, few flowers atop upright to somewhat lax stems, stems not hairy. Youngs
Bay, Brownsmead, Svensen Island, all should be likely places for it.
