  parlum 
  ; 
  I 
  have 
  not 
  yet 
  seen 
  specimens 
  from 
  N. 
  America, 
  

   but 
  I 
  do 
  not 
  for 
  a 
  moment 
  doubt 
  that 
  it 
  will 
  be 
  found 
  there 
  in 
  

   swamps 
  on 
  the 
  shores 
  of 
  lakes 
  and 
  ponds. 
  

  

  ^. 
  Stem 
  leaves 
  larger, 
  isosceles- 
  triangular, 
  usually 
  with 
  fibrils 
  in 
  

   the 
  apical 
  part. 
  Branch 
  leaves 
  broadly 
  bordered 
  and 
  mostly 
  

   involute 
  far 
  down 
  on 
  the 
  margins; 
  on 
  the 
  inner 
  side 
  with 
  few 
  

   or 
  many 
  pores 
  in 
  the 
  cell-angles, 
  on 
  the 
  outer 
  side 
  with 
  only 
  

   small 
  pores 
  in 
  the 
  upper 
  angles 
  of 
  the 
  cells.
