   withstanding 
  this

  a

  discrep- 
  

   ancy 
  in 
  the 
  arrangement 
  of 
  the 
  perithecia, 
  the 
  species 
  is 
  so 
  

   remarkable 
  and 
  so 
  well 
  characterized 
  that 
  I 
  cannot 
  believe 
  

   our 
  plant 
  to 
  be 
  specifically 
  distinct. 
  It 
  is 
  the 
  smallest 
  Tor- 
  

   rubia 
  known 
  to 
  me, 
  and 
  does 
  not 
  well 
  agree 
  with 
  the 
  gen-

  character. 
  It 
  occurs 
  on 
  young 
  and

  grown 
  as

   as 
  on

  but 
  I 
  have 
  not 
  been 
  able 
  to 
  deter- 
  

   mine 
  whether 
  it 
  attacks 
  the 
  insect

  Related 
  to 
  and 
  intermediate 
  between 
  T. 
  Ramnelii 
  and 
  T. 
  

   Carolinensis. 
  The 
  stem 
  of 
  the 
  plant 
  is 
  about 
  equal 
  in 
  

   length 
  to 
  the 
  club 
  or 
  peri 
  thecia-b 
  earing 
  part. 
  The 
  perithe- 
  

   cia 
  are 
  more 
  loosely 
  placed 
  at 
  the 
  extremities 
  of 
  the 
  club, 
  

   thereby 
  giving 
  it 
  a 
  subfusiform 
  shape. 
  The 
  spores 
  are 
  more 
  

   slender 
  than 
  those 
  of 
  T. 
  Carolinensis 
  but 
  the 
  plant 
  itself 
  is 
  

   less 
  elongated 
  and 
  slender.
