Sticky Leaf Arnica (Arnica ovata Greene)

Also classified as Arnica diversifolia Greene, Arnica √ódiversifolia.

Both BONAP and POWO have merged rayless arnica (Arnica (√ó)diversifolia)(sometimes thought to be a hybrid) into this species. Prior to the merge, according to the USDA, this species was only thought to occur in Canada, so the US populations of this taxon may all correspond to populations formerly labeled as Arnica diversifolia.
