  existence 
  of 
  red 
  species 
  in 
  the 
  same 
  genus, 
  or 
  

   in 
  some 
  rare 
  cases, 
  in 
  nearly 
  allied 
  genera. 
  

   Colors 
  that 
  are 
  not 
  systematically 
  present 
  in 
  

   the 
  group 
  to 
  which 
  a 
  white 
  species 
  belongs 
  are 
  

   only 
  produced 
  in 
  its 
  varieties 
  in 
  extremely 
  rare 
  

   cases. 
  

  

  We 
  may 
  quote 
  some 
  special 
  rules, 
  indicated 
  

   by 
  Hildebrand. 
  Blue 
  species 
  are 
  in 
  the 
  main 
  

   very 
  rare, 
  and 
  so 
  are 
  blue 
  varieties 
  of 
  white 
  

   species 
  also. 
  Carnations, 
  Asiatic 
  or 
  cultivated 
  

   buttercups 
  (Ranunculus 
  asiaticus), 
  Mirabilis, 
  

   poppies, 
  Gladiolus, 
  Dahlia, 
  and 
  some 
  other 
  

   highly 
  cultivated 
  or 
  very 
  old 
  garden-plants 
  have 
  

   not 
  been 
  able 
  to 
  produce 
  true 
  blue 
  flowers. 
  But 
  

   the 
  garden-anemone 
  (Anemone 
  coronaria) 
  has 
  

   allies 
  with 
  very 
  fine 
  blue 
  flowers. 
  The 
  common 
  

   stock 
  has 
  bluish 
  varieties 
  and 
  is 
  allied 
  to 
  Aubre- 
  

   tia 
  and 
  Hesperis, 
  and 
  gooseberries 
  have 
  a 
  red 
  

   form, 
  recalling 
  the 
  ordinary 
  currant. 
  In 
  nearly 
  

   all 
  other 
  instances 
  of 
  blue 
  or 
  red 
  varieties 
  every 
  

   botanist 
  will 
  be 
  able 
  to 
  point 
  out 
  some 
  allied 
  red 
  

   or 
  blue 
  species, 
  as 
  an 
  indication 
  of 
  the 
  probable 
  

   source 
  of 
  the 
  varietal 
  character. 
  

  

  Dark 
  spots 
  on 
  the 
  lower 
  parts 
  of 
  the 
  petals 
  

   of 
  some 
  plants 
  afford 
  another 
  instance, 
  as 
  in 
  

   poppies 
  and 
  in 
  the 
  allied 
  Glaucium, 
  where 
  they 
  

   sometimes 
  occur 
  as 
  varietal 
  and 
  in 
  other 
  cases 
  

   as 
  specific 
  marks. 
  

  

  The 
  yellow 
  fails 
  in 
  many 
  highly 
  developed
