  Fluctuations 
  

  

  joined 
  all 
  around, 
  resembling 
  the 
  best 
  types 
  of 
  

   lilies 
  and 
  amaryllis. 
  

  

  Striking 
  as 
  this 
  result 
  unquestionably 
  is, 
  it 
  

   remains 
  doubtful 
  as 
  to 
  what 
  part 
  of 
  it 
  is 
  due 
  to 
  

   the 
  discovery 
  and 
  introduction 
  of 
  new 
  large 
  

   flowered 
  species, 
  and 
  what 
  to 
  the 
  selection 
  of 
  

   the 
  extremes 
  of 
  fluctuating 
  variability. 
  As 
  far 
  

   as 
  I 
  have 
  been 
  able 
  to 
  ascertain 
  however, 
  and 
  

   according 
  to 
  the 
  evidence 
  given 
  to 
  me 
  by 
  Mr. 
  

   Crozy, 
  selection 
  has 
  had 
  the 
  largest 
  part 
  in 
  re- 
  

   gard 
  to 
  the 
  size, 
  while 
  the 
  color-patterns 
  are 
  

   introduced 
  qualities. 
  

  

  The 
  scientific 
  analysis 
  of 
  other 
  intricate 
  ex- 
  

   amples 
  is 
  still 
  more 
  difficult. 
  To 
  the 
  practical 
  

   breeder 
  they 
  often 
  seem 
  very 
  simple, 
  but 
  the 
  

   student 
  of 
  heredity, 
  who 
  wishes 
  to 
  discern 
  the 
  

   different 
  factors, 
  is 
  often 
  quite 
  puzzled 
  by 
  this 
  

   apparent 
  simplicity. 
  So 
  it 
  is 
  in 
  the 
  case 
  of 
  

   the 
  double 
  lilacs, 
  a 
  large 
  number 
  of 
  varieties 
  of 
  

   which 
  have 
  recently 
  been 
  originated 
  and 
  intro- 
  

   duced 
  into 
  commerce 
  by 
  Lemoine 
  of 
  Nancy. 
  In 
  

   the 
  main 
  they 
  owe 
  their 
  origin 
  to 
  the 
  crossing 
  

   and 
  recrossing 
  of 
  a 
  single 
  plant 
  of 
  the 
  old 
  

   double 
  variety 
  with 
  the 
  numerous 
  existing 
  

   single-flowered 
  sorts. 
  

  

  This 
  double 
  variety 
  seems 
  to 
  be 
  as 
  old 
  as 
  the 
  

   culture 
  of 
  the 
  lilacs. 
  It 
  was 
  already 
  known 
  to 
  

   Hunting, 
  who 
  described 
  it 
  in 
  the 
  year 
  1671. 
  

   Two 
  centuries 
  afterwards, 
  in 
  1870,
