  cussions 
  we 
  may 
  state 
  that 
  wild 
  new 
  elementary 
  

   species 
  and 
  varieties 
  are 
  recorded 
  to 
  have 
  

   appeared 
  from 
  time 
  to 
  time. 
  Invariably 
  this 
  

   happened 
  by 
  sudden 
  leaps 
  and 
  without 
  interme- 
  

   diates. 
  The 
  mutants 
  are 
  constant 
  when 
  prop- 
  

   agated 
  by 
  seed, 
  and 
  at 
  once 
  constitute 
  a 
  new 
  

   race. 
  In 
  rare 
  instances 
  this 
  may 
  be 
  of 
  sufficient 
  

   superiority 
  to 
  win 
  a 
  place 
  for 
  itself 
  in 
  nature, 
  

   but 
  more 
  often 
  it 
  has 
  qualities 
  which 
  have 
  led 
  to 
  

   its 
  introduction 
  into 
  gardens 
  as 
  an 
  ornamental 
  

   plant 
  or 
  into 
  botanical 
  gardens 
  by 
  reason 
  of 
  the 
  

   interest 
  afforded 
  by 
  their 
  novelty, 
  or 
  by 
  their 
  

   anomaly. 
  

  

  Many 
  more 
  mutations 
  may 
  be 
  supposed 
  to 
  be 
  

   taking 
  place 
  all 
  around 
  us, 
  but 
  artificial 
  sowings 
  

   on 
  a 
  large 
  scale, 
  combined 
  with 
  a 
  close 
  exam- 
  

   ination 
  of 
  the 
  seedlings 
  and 
  a 
  keen 
  appreciation 
  

   of 
  the 
  slightest 
  indications 
  of 
  deviation 
  seem 
  

   required 
  to 
  bring 
  them 
  to 
  light.
