  and 
  also 
  

   much 
  resembling 
  it 
  ; 
  tufts 
  loose

  whitish. 
  Stem 
  cortex 
  variably 
  formed 
  of 
  

   2-3 
  or 
  3-4 
  strata 
  of 
  cells, 
  the 
  superficial 
  cells 
  with 
  isolated, 
  

   H 
  regularly 
  distributed, 
  small 
  or 
  large 
  pores 
  without 
  rings 
  ; 
  

   the 
  inner

  with 
  numerous 
  small 
  pores. 
  Stem 
  leaves 
  

   arge, 
  broad 
  linguiform, 
  with 
  somewhat

   •"hombic, 
  mostly 
  without 
  cross-partitions, 
  but 
  with 
  delicate 
  

   membrane-plaits, 
  all 
  the 
  hyaline 
  cells 
  with 
  membrane 
  thin- 
  

   nings, 
  which 
  rarely 
  at 
  the 
  edges 
  towards 
  the
