  full 
  size. 
  Absolute 
  sterility 
  is 
  the 
  natural 
  con- 
  

   sequence 
  of 
  this 
  state 
  of 
  things. 
  

  

  Hence 
  it 
  is 
  impossible 
  to 
  have 
  races 
  of 
  petal- 
  

   onianous 
  types. 
  If 
  the 
  abnormality 
  happens 
  to 
  

   show 
  itself 
  in 
  a 
  species, 
  which 
  normally 
  prop- 
  

   agates 
  itself 
  in 
  an 
  asexual 
  way, 
  the 
  type 
  may 
  

   become 
  a 
  vegetative 
  variety, 
  and 
  be 
  multiplied 
  

   by 
  bulbs, 
  buds 
  or 
  cuttings, 
  etc. 
  Some 
  cultivated 
  

   anemones 
  and 
  crowfoots 
  (Ranunculus) 
  are 
  of 
  

   this 
  character, 
  and 
  even 
  the 
  marsh-marigold 
  

   (Caltha 
  palustris) 
  has 
  a 
  petalomanous 
  variety. 
  

   I 
  once 
  found 
  in 
  a 
  meadow 
  such 
  a 
  form 
  of 
  the 
  

   meadow-buttercup 
  (Ranunculus 
  acris), 
  dnd 
  suc- 
  

   ceeded 
  in 
  keeping 
  it 
  in 
  my 
  garden 
  for 
  several 
  

   years, 
  but 
  it 
  did 
  not 
  make 
  seeds 
  and 
  finally 
  

   died. 
  Camellias 
  are 
  known 
  to 
  have 
  both 
  types 
  

   of 
  double 
  flowers. 
  The 
  petalomanous 
  type 
  is 
  

   highly 
  regular 
  in 
  structure, 
  so 
  much 
  so 
  as 
  to 
  be 
  

   too 
  uniform 
  in 
  all 
  its 
  parts 
  to 
  be 
  pleasing, 
  while 
  

   the 
  conversion 
  of 
  stamens 
  into 
  petals 
  in 
  the 
  al- 
  

   ternative 
  varieties 
  gives 
  to 
  these 
  flowers 
  a 
  more 
  

   lively 
  diversity 
  of 
  structure. 
  Lilies 
  have 
  a 
  va- 
  

   riety 
  called 
  Lilium 
  candidum 
  fore 
  pleno, 
  in 
  

   which 
  the 
  flowers 
  seem 
  to 
  be 
  converted 
  into 
  

   a 
  long 
  spike 
  of 
  bright, 
  white 
  narrow 
  bracts, 
  

   crowded 
  on 
  an 
  axis 
  which 
  never 
  seems 
  to 
  cease 
  

   their 
  production. 
  

  

  It 
  is 
  manifestly 
  impossible 
  to 
  decide 
  how 
  all 
  

   such 
  sterile 
  double 
  flowers 
  have 
  originated.
