white marsh marigold, Psychophila leptosepala

I remember white marsh marigold from my first trip to the Rocky Mountains. It was fun to see this version of our eastern marsh marigold high on the fourteeners of Colorado. Except for color, it was very much like our yellow ones. Or maybe not. Modern DNA analysis reveals that it is more closely related to similar plants in South America, and even New Zealand and Australia. It has been moved from the old genus of Caltha to its current classification. Some even put it in a family separated from the old bunch of buttercups. I'm still waiting for the final ruling on that one from the courts of professional botanists. White marsh marigold grows in mountain meadows in AK, AZ, CA, CO, ID, MT, MN, NV, OR, UT, WA, WY, AB, BC, and YK. Mt. Evans National Park, Clear Creek Co CO, 6/18/13
