  T. 
  Holm 
  — 
  Pogonia 
  ojphioglossoides. 
  

  

  stem 
  (T). 
  Characteristic 
  of 
  the 
  rhizome 
  is 
  the 
  monopodial 
  

   growth, 
  which 
  ceases, 
  however, 
  when 
  the 
  flower-bearing 
  stem 
  

   dies 
  away. 
  After 
  that 
  time 
  it 
  becomes 
  a 
  sympodium, 
  as 
  the 
  

   axillary 
  bud 
  (h) 
  will 
  develop 
  and 
  continue 
  the 
  growth 
  of 
  the 
  

   rhizome. 
  This 
  is, 
  however, 
  not 
  the 
  only 
  bnd, 
  which 
  is 
  visible 
  

  

  at 
  the 
  present 
  stage, 
  since 
  another 
  one, 
  though 
  dormant, 
  is 
  

   developed 
  in 
  the 
  axil 
  of 
  the 
  leaf 
  L 
  2 
  . 
  It 
  is 
  evident 
  that 
  this 
  

   dormant 
  bud 
  would 
  have 
  grown 
  out 
  into 
  a 
  branch, 
  if 
  the 
  upper 
  

   part 
  of 
  the 
  rhizome 
  might 
  have 
  become 
  injured, 
  but 
  not 
  other- 
  

   wise. 
  The 
  same 
  mode 
  of 
  growth 
  is, 
  also, 
  to 
  be 
  observed 
  in 
  

   such 
  specimens, 
  which 
  are 
  yet 
  purely 
  vegetative 
  as 
  the 
  one 
  

   drawn 
  in 
  fig. 
  2.
