    Is this Nodding Arnica (Arnica lessingii) or Snow Arnica (Arnica frigida)? These plants were found late June in Denali National Park. I suspect they are Nodding Arnica, but I am not sure.

    Thank you Wendy! I have seen these pages, but I am still undecided. I was hoping someone knowing these species would chime in.

    I would lean toward it not being Arnica lessingii, though I am not familiar with Arnica frigida.

    Thanks Daniel! I tend to agree. Having looked at numerous web pages, I now suspect they are Snow Arnica. One uncertainty, of course, is the degree of mislabeling of photos posted on the internet. Thats one of the dangers trying to determine species solely based on online photos.

    Well, my personal experience with Arnica lessingii is that it very much nods and the ray flowers hang instead of flare.
