  Trillium

  Pine

  Clinton. 
  

   July. 
  

  

  The 
  tissues 
  at 
  length 
  fall 
  out 
  from 
  the 
  affected 
  spot, 
  leaving 
  aper- 
  

   tures 
  through 
  the 
  leaf. 
  The 
  perithecia 
  are 
  less 
  regularly 
  disposed 
  

   near 
  the 
  center 
  of 
  the 
  spots. 
  Judge 
  Clinton 
  also 
  sends 
  a 
  variety 
  on 
  

   leaves 
  of 
  Viola 
  rotundifolia 
  in 
  which 
  the 
  concentric 
  arrangement 
  of 
  

   the 
  perithecia 
  is 
  not 
  at 
  all 
  perceptible, 
  but 
  I 
  detect 
  no 
  other 
  difference.
