  The

  of 
  a 
  remarkable 
  rosaceous 
  plant,

  in 
  Its 
  flowers 
  and 
  fruit 
  verj^ 
  close 
  to 
  another 
  peculiar 
  western 
  

   species, 
  the 
  Sfirma 
  cmsfitosa 
  of 
  Nuttall, 
  has 
  led 
  me 
  to 
  an 
  ex- 
  

   amination

  entire 
  group

  allied 
  species,

   which

  Wgh 
  up 
  on 
  th? 
  precipitous 
  

   river 
  at 
  "The 
  Gate 
  of 
  the 
  Mountains," 
  near 
  Townsend, 
  

   Montana. 
  It 
  sends 
  its 
  long 
  roots 
  deep 
  into 
  the 
  crevices 
  of 
  

   the 
  rocks, 
  while 
  the 
  slender 
  woody 
  branches, 
  many 
  times 
  sub- 
  

   divided, 
  are 
  crowded 
  together 
  and 
  densely 
  covered 
  with 
  the 
  

   long-persistent 
  imbricated 
  leaves, 
  which 
  are 
  only 
  one 
  or 
  two 
  

   mes 
  long. 
  Only 
  the 
  outer 
  leaves 
  of 
  the 
  mass 
  remain 
  green, 
  

   the 
  lower 
  soon 
  becoming 
  a 
  light 
  rusty 
  brown. 
  The 
  flowers 
  

   are 
  wholly 
  concealed, 
  hidden 
  away 
  within 
  the 
  clump 
  and 
  

   sohtary 
  on 
  the 
  ends 
  of 
  the 
  branches, 
  but 
  often 
  appearing 
  

   J^teral 
  from 
  the 
  prolongation 
  of 
  a 
  side 
  shoot. 
  The 
  very 
  

   Short 
  pedicel 
  does 
  not 
  raise 
  the 
  flower 
  above 
  the 
  leaves 
  that 
  

   surround 
  it. 
  The 
  characters 
  of 
  the 
  flower 
  and 
  fruit 
  are 
  so

  Mr. 
  Faxon 
  has

  has
