  FIVE-LEAVED 
  CLOVER 
  

  

  Every 
  one 
  knows 
  the 
  " 
  four-leaved 
  " 
  clover. 
  

   It 
  is 
  occasionally 
  found 
  on 
  lawns, 
  in 
  pastures 
  

   and 
  by 
  the 
  roadsides. 
  Specimens 
  with 
  five 
  leaf- 
  

   lets 
  may 
  be 
  found 
  now 
  and 
  then 
  in 
  the 
  same 
  

   place, 
  or 
  on 
  the 
  same 
  plant, 
  but 
  these 
  are 
  rarer. 
  

   I 
  have 
  often 
  seen 
  isolated 
  plants 
  with 
  quater- 
  

   nate 
  leaves, 
  but 
  only 
  rarely 
  have 
  I 
  observed 
  in- 
  

   dividuals 
  with 
  more 
  than 
  one 
  such 
  leaf. 
  

  

  The 
  two 
  cases 
  are 
  essentially 
  dissimilar. 
  

   They 
  may 
  appear 
  to 
  differ 
  but 
  little 
  morpholog- 
  

   ically, 
  but 
  from 
  the 
  point 
  of 
  view 
  of 
  heredity 
  

   they 
  are 
  quite 
  different. 
  Isolated 
  quaternate 
  

   leaves 
  are 
  of 
  but 
  little 
  interest, 
  while 
  the 
  occur- 
  

   rence 
  of 
  many 
  on 
  the 
  same 
  individual 
  indicates 
  a 
  

   distinct 
  variety. 
  In 
  making 
  experiments 
  upon 
  

   this 
  point 
  it 
  is 
  necessary 
  to 
  transplant 
  the 
  di- 
  

   vergent 
  individuals 
  to 
  a 
  garden 
  in 
  order 
  to 
  

   furnish 
  them 
  proper 
  cultural 
  conditions 
  and 
  

   to 
  keep 
  them 
  under 
  constant 
  observation. 
  When 
  

   a 
  plant 
  bearing 
  a 
  quaternate 
  leaf 
  is 
  thus 
  

   transplanted 
  however, 
  it 
  rarely 
  repeats
