Fun, weird, helpful, or little known fact
This arnica has broad, slightly toothed leaves (unlike A. rydbergii), red-tipped phyllaries, is glandular, and is less common than the similar Arnica mollis (which is usually taller and often has three flowerheads). Perhaps the best distinguishing feature is its pappus which consists of white, barbellate (short-barbed) hairs, while A. mollis has a pappus that is tawny/tan and subplumose (feathery).
