  This 
  species 
  is 
  already 
  known 
  to 
  inhabit 
  Canada, 
  New 
  

   Hampshire, 
  Massachusetts, 
  New 
  Jersey, 
  and 
  Miquelon 
  

   Island 
  {Delamare). 
  How 
  Cardot 
  can 
  decide 
  to 
  include 
  this 
  

   fine 
  characteristic 
  species 
  as 
  a 
  subspecies 
  of 
  S, 
  acutifolitim 
  

   (Ehrh.) 
  I 
  can 
  not 
  comprehend. 
  Qiiite 
  as 
  properly 
  might 
  he 
  

   also 
  have 
  considered 
  S. 
  fimbriatum 
  as 
  belonging 
  to 
  S. 
  acuti- 
  

   lohum.^ 
  Both 
  species 
  are 
  surely 
  specifically 
  distinct 
  from 
  S. 
  

   acutifolium 
  by 
  the 
  numerous 
  pores 
  in 
  the 
  stem 
  cortex, 
  

   by 
  the 
  occurrence 
  of 
  resorption 
  in 
  the 
  stem 
  leaves, 
  as 
  

   well 
  as 
  by 
  the 
  quite 
  different 
  pore 
  structure 
  of 
  the 
  branch 
  

   leaves. 
  S. 
  Girgensohnii 
  Is 
  very 
  widely 
  diffused 
  in 
  the 
  

   northern 
  parts 
  of 
  the 
  northern 
  hemisphere". 
  I 
  have 
  a 
  speci- 
  

   men 
  from 
  Japan 
  (Herb. 
  Mitten), 
  which 
  is 
  monoicous. 
  S. 
  

   Hookeri 
  C. 
  Miill. 
  from 
  the 
  Himalaya 
  is 
  only 
  a 
  very 
  delicate 
  

   squarrose-leaved 
  form 
  of 
  this 
  species, 
  and 
  in 
  anatomical 
  

   structure 
  agrees 
  perfectly 
  with 
  S. 
  Girgensohnii. 
  

  

  The 
  most 
  important 
  of 
  the 
  forms 
  received 
  from
