ARNICA FULGENS Pursh, Fl. Am. Sept. 2: 527. 1814.
I think that this is distinct from A. alpina, differing in the fol lowing characters: taller, stem often 3-4 dm. high, shorter pubes cence, often 3 or 4 smaller heads, much broader and dentate leaves and often as many as many as 3 or 4 pairs of stem leaves.
It was collected by Mr. Flodman at Little Belt Pass, no. 891. 1896. My own specimens, no. 823, from the Black Hills, also be long here.
