  considers 
  this 
  species 
  as 
  an 
  incompletely 
  

   developed 
  form 
  of 
  S. 
  subsecundu.,,. 
  There 
  is 
  indeed 
  no 
  

   doubt 
  that 
  the 
  thick 
  branchless 
  stem 
  structure 
  of 
  this 
  species 
  

   gives 
  the 
  impression 
  that 
  it 
  may 
  be 
  a 
  young 
  plant 
  of 
  some 
  

   subsecundum 
  form 
  ; 
  but

  almost 
  regular

  of
