  heterophyllus 
  Schreb. 
  

  

  Specimens 
  referable 
  to 
  form 
  longvpedunculatus 
  Morong 
  were 
  

   collected 
  near 
  the 
  outlet 
  of 
  Seneca 
  lake. 
  

  

  Potamogeton 
  lucens 
  L. 
  

  

  This 
  species 
  occurs 
  in 
  Oneida 
  and 
  Cayuga 
  lakes. 
  The 
  var. 
  

  

  Connecticutensis 
  Bobbins 
  was 
  collected 
  in 
  Stissing 
  pond 
  near 
  

  

  Pine 
  Plains. 
  This 
  is 
  the 
  only 
  station 
  recorded

  Herkimer 
  county. 
  July. 
  This 
  is 
  P. 
  marinus 
  of 
  

   the 
  Manual. 
  It 
  is 
  scarcely 
  separable, 
  in 
  some 
  of 
  its 
  forms, 
  from 
  

   P. 
  pectinatus 
  in 
  the 
  absence 
  of 
  fruit, 
  and 
  it 
  has 
  probably 
  been 
  

   often 
  confused 
  with 
  that 
  species. 
  

  

  Potamogeton 
  pectinatus

  A 
  form 
  of 
  this 
  species 
  is 
  abundant 
  in 
  Warners 
  lake, 
  Albany 
  

   county, 
  in 
  which 
  the 
  peduncle 
  is 
  whitish 
  and 
  8 
  to 
  12 
  inches 
  long. 
  

  

  In 
  the 
  E".

  Flora 
  nine 
  species 
  of 
  Potamogeton 
  are 
  

   recorded. 
  The 
  number 
  of 
  species 
  now 
  known 
  to 
  belong 
  to 
  the 
  

   State 
  is 
  twenty-seven, 
  all 
  of 
  which,
