  ing, 
  the 
  notes 
  being 
  ordinarily 
  made 
  for 
  com- 
  

   mercial 
  purposes, 
  and 
  often 
  only 
  at 
  the 
  date 
  of 
  

   introduction 
  into 
  trade, 
  when 
  the 
  preceding 
  

   stages 
  of 
  the 
  novelty 
  may 
  have 
  been 
  partly 
  for- 
  

   gotten. 
  

  

  With 
  this 
  necessary 
  prelude 
  I 
  will 
  now 
  give 
  a 
  

   condensed 
  survey 
  of 
  the 
  historical 
  facts 
  relat- 
  

   ing 
  to 
  the 
  origin 
  of 
  new 
  horticultural 
  varieties. 
  

   An 
  ample 
  description 
  has 
  been 
  given 
  recently 
  

   by 
  Korshinsky, 
  a 
  Russian 
  writer, 
  who 
  has 
  

   brought 
  together 
  considerable 
  historical 
  mate- 
  

   rial 
  as 
  evidence 
  of 
  the 
  sudden 
  appearance 
  of 
  

   novelties 
  throughout 
  the 
  whole 
  realm 
  of 
  garden- 
  

   plants. 
  

  

  The 
  oldest 
  known, 
  and 
  at 
  the 
  same 
  time 
  one 
  

   of 
  the 
  most 
  accurately 
  described 
  mutations 
  is 
  

   the 
  origin 
  of 
  the 
  cut-leaved 
  variety 
  of 
  the 
  

   greater 
  celandine 
  or 
  Chelidonium 
  majus. 
  This 
  

   variety 
  has 
  been 
  described 
  either 
  as 
  such, 
  or 
  as 
  

   a 
  distinct 
  species, 
  called 
  Chelidonium 
  lacimatum* 
  

   Miller. 
  

  

  It 
  is 
  distinguished 
  from 
  the 
  ordinary 
  species, 
  

   by 
  the 
  leaves 
  being 
  cut 
  into 
  narrow 
  lobes, 
  with 
  

   almost 
  linear 
  tips, 
  a 
  character 
  which 
  is, 
  as 
  we 
  

   have 
  seen 
  on 
  a 
  previous 
  occasion, 
  repeated 
  in 
  

   the 
  petals. 
  It 
  is 
  at 
  present 
  nearly 
  as 
  commonly 
  

   cultivated 
  in 
  botanical 
  gardens 
  as 
  the 
  C. 
  majus, 
  

   and 
  has 
  escaped 
  in 
  many 
  localities 
  and 
  is 
  ob- 
  

   served 
  to 
  thrive 
  as 
  readilv 
  as 
  the 
  native 
  wild
