  There 
  has 
  probably 
  been 
  but 
  one 
  collection 
  of 
  this 
  form 
  made, 
  

   although 
  dates 
  on 
  the 
  different 
  packets 
  in 
  herbaria 
  are 
  not 
  uniform. 
  

   The 
  date 
  on 
  the 
  Sydow 
  distribution 
  is 
  '* 
  31. 
  5. 
  1894," 
  but 
  a 
  packet 
  

   in 
  the 
  herbarium 
  of 
  the 
  New 
  York 
  Botanical 
  Garden, 
  reads 
  

   "March 
  31, 
  1894," 
  so 
  I 
  assume 
  that 
  "5" 
  is 
  a 
  misreading 
  of 
  "3." 
  

   The 
  Bartholomew 
  distribution 
  gives 
  March 
  ii, 
  1893. 
  This 
  ma- 
  

   terial 
  was 
  received 
  through 
  Professor 
  E, 
  W. 
  D. 
  Holway, 
  who 
  

  

  J 
  

  

  obtained 
  it 
  from 
  the 
  collector. 
  Possibly 
  there 
  were 
  two 
  collections 
  

   made 
  in 
  consecutive 
  years, 
  but 
  the 
  appearance 
  of 
  the 
  material 
  

   does 
  not 
  warrant 
  the 
  assumption. 
  I 
  am 
  using 
  the 
  material 
  dis-

  tributed

  The 
  specimen 
  from 
  which 
  this 
  description 
  is 
  drawn 
  Is 
  in 
  the 
  

  

  cryptogamic 
  herbarium 
  of 
  the 
  New 
  York 
  Botanical 
  Garden, 
  and 
  

   consists 
  of 
  a 
  single 
  leaf 
  bearing 
  three 
  groups 
  of 
  aecia. 
  The 
  speci- 
  

   men 
  appears 
  to 
  have 
  been 
  sent 
  to 
  Mr. 
  J. 
  B. 
  Ellis 
  by 
  Waghorne, 
  

   although 
  the 
  collector's 
  name 
  is 
  not 
  written 
  on 
  the 
  packet. 
  The 
  

   packet 
  bears 
  the 
  doubtful 
  date 
  of 
  " 
  I3-7-82," 
  which 
  possibly 
  indi- 
  

   cates 
  that 
  the 
  material 
  was 
  secured 
  on 
  July 
  13, 
  1882. 
  A 
  note 
  

   accompanies 
  the 
  specimen, 
  reading, 
  '*This 
  seems 
  to 
  be 
  on 
  various 
  

   leaves 
  and 
  stems 
  of 
  this 
  Mitella; 
  I 
  have 
  only 
  one 
  leaf 
  more." 
  

   Whether 
  this 
  was 
  written 
  by 
  Mr. 
  Waghorne 
  or 
  Mr. 
  Ellis 
  is 
  uncer- 
  

   tain. 
  There 
  seems 
  to 
  be 
  no 
  doubt 
  about 
  the 
  idei 
  

  

  tity 
  

  

  M 
  

  

  and 
  apparently 
  not 
  heretofore 
  published, 
  should 
  be 
  established. 
  

   The 
  form 
  appears 
  to 
  be 
  a 
  heteroecious 
  one.
