That the authors of the list of " Mosses of Alaska" failed to appreciate 

 so remarkable a species, one of the most interesting collected by the party, 

 indeed, seems rather singular, since they have rather gone out of the way in 

 an attempt to name slight variations that often might far better be included 

 with the species. R. S. Williams,
