  this 
  locality, 
  it 
  might 
  almost 
  be 
  called 
  abundant. 
  In 
  many

  was 
  associated 
  with 
  it 
  the 
  grape

  This 
  latter 
  species, 
  however, 
  tended 
  to 
  grow 
  

   farther 
  into 
  the 
  forest, 
  and 
  was 
  not

  This 
  delicate 
  variety 
  is 
  represented 
  by 
  but 
  one 
  collection 
  in 
  

   the 
  herbarium 
  of 
  the 
  University, 
  although 
  the 
  typical 
  form 
  of 
  the 
  

   species 
  is 
  a 
  very 
  common 
  fern 
  throughout 
  the 
  western 
  portion 
  of 
  the 
  

   state, 
  growing 
  on 
  rocky 
  soil 
  and 
  In 
  rocky 
  crevices 
  up 
  to 
  an 
  altitude 
  

   of 
  about 
  3,000 
  meters. 
  So 
  far 
  as 
  I 
  have 
  been 
  able 
  to 
  ascertain, 
  the 
  

   variety 
  has 
  not 
  been 
  reported 
  from 
  any 
  of 
  the 
  region 
  surrounding 
  

   Montana. 
  The 
  specimen 
  cited 
  is 
  as 
  large 
  as 
  the 
  typical 
  form 
  of 
  

   the 
  species, 
  but 
  the 
  frond 
  is 
  much 
  thinner 
  and 
  the 
  pinnules 
  are 
  

   more 
  toothed 
  and 
  finer-pointed. 
  The 
  following 
  specimen 
  in 
  the 
  

   herbarium 
  of 
  the 
  University 
  tends 
  verj" 
  strongly 
  to 
  approach 
  this 
  

   variety.
