Kcntrophyta Gray but is distin- 

 guished at once by its matted habit, its green leaves, its purple, 

 peduncled flowers as well as by its habitat. This is strictly alpine,

forming mats below the snow drifts at the upper limits of vege- 

 tation. Type specimen, no. 2445, from the higher summits of 

 the Big Horn Mts., near Dome Lake, July 18, 1896. 



I am again indebted to Dr. Rydberg for a comparison of the 

 co-types, sent to Columbia University^ with specimens of nearly 

 related species. Most of them I also personally studied critically 

 at the Herbarium of the Missouri Botanical Garden. Of these, as 

 well as of those published in previous papers, representative speci- 

 mens will be placed, whenever possible, in other herbaria including 

 Mo. Bot. Garden, Gray, National, Cornell, etc.. The types are all 

 preserved in Herb. University of Wyoming.
