  In 
  Hedwigia, 
  1889, 
  P- 
  303-308, 
  I 
  attempted 
  to 
  show 
  that 
  

   this 
  species, 
  on 
  account 
  of 
  its 
  anatomical 
  structure, 
  should 
  be 
  

   placed 
  among 
  the 
  forms 
  o{ 
  S. 
  imhricatum 
  (Hornsch. 
  ) 
  Ru.ss.=: 
  

   o.

  But 
  I 
  did 
  not 
  then 
  in 
  m^^ 
  investigations 
  take 
  

   into 
  consideration 
  the 
  structure 
  of 
  the 
  cortex 
  of 
  the 
  branches 
  

   wherein 
  the 
  two 
  species 
  differ 
  from 
  each 
  other, 
  so 
  now 
  I 
  do 
  

   not 
  hesitate 
  to 
  accord 
  to 
  S 
  Portoricense 
  its 
  right 
  to 
  the 
  rank 
  

   of 
  a 
  distinct 
  species, 
  by 
  reason 
  of 
  the 
  peculiar 
  saccately 
  curved 
  

   transverse 
  walls 
  of 
  the 
  cortical 
  cells 
  of 
  its 
  branches, 
  such 
  

   as 
  I 
  have 
  observed 
  in 
  no 
  other 
  exotic 
  species 
  of 
  the 
  Cymbi- 
  

  

  FOLIA. 
  

  

  b. 
  Transverse 
  walls 
  of 
  the 
  cortical 
  cells 
  of 
  the 
  branches 
  not 
  bent 
  

   downward 
  but 
  level, 
  the 
  cells 
  much 
  narrower 
  than 
  in 
  the 
  preceding 
  ; 
  

   the 
  hyaUne 
  cells 
  of 
  the 
  branch 
  leaves 
  usually 
  only 
  half 
  as 
  wide. 
  

   Chlorophyllose 
  cells 
  in 
  cross 
  section 
  usually 
  equilateral-triangular, 
  

   placed 
  on 
  the 
  inner 
  side 
  between 
  the 
  hyaline 
  celli, 
  on 
  the 
  outside 
  

   completely 
  enclosed. 
  The 
  hyaline 
  cells 
  within, 
  so 
  far 
  as 
  they 
  are 
  

   united 
  to 
  the 
  green 
  cells, 
  usually 
  furnished 
  with 
  comb-fibrils, 
  which 
  

   occur 
  sometimes 
  abundantly, 
  sometimes 
  only 
  scantily 
  near 
  the 
  

   base 
  of 
  the 
  leaf, 
  and 
  sometimes, 
  though 
  rarely, 
  are 
  entirely 
  wanting.
