  of 
  the 
  lips 
  of 
  the 
  flower 
  around 
  the 
  throat, 
  

   brightening, 
  as 
  it 
  seems, 
  the 
  entrance 
  for 
  the 
  

   visiting 
  insects. 
  In 
  many 
  of 
  the 
  red 
  or 
  reddish 
  

   varieties 
  this 
  one 
  yellow 
  patch 
  remains, 
  while 
  

   the 
  general 
  yellow 
  hue 
  fails. 
  In 
  the 
  variety 
  

   called 
  " 
  Brilliant 
  " 
  the 
  yellow 
  ground 
  makes 
  

   the 
  red 
  color 
  more 
  shiny, 
  and 
  if 
  it 
  is 
  absent 
  the 
  

   pure 
  carmine 
  tinge 
  predominates. 
  

  

  It 
  is 
  readily 
  seen, 
  that 
  in 
  the 
  ordinary 
  form 
  

   the 
  lips 
  are 
  of 
  a 
  darker 
  red 
  than 
  the 
  tube. 
  This 
  

   evident 
  dissimilarity 
  indicates 
  some 
  complexity. 
  

   And 
  in 
  fact 
  we 
  have 
  two 
  varieties 
  which 
  exhibit 
  

   the 
  two 
  causes 
  of 
  this 
  attribute 
  separately. 
  One 
  

   of 
  them 
  is 
  called 
  " 
  Delila," 
  and 
  has 
  the 
  red 
  

   color 
  limited 
  to 
  the 
  lips, 
  whilst 
  the 
  tube 
  is 
  pure 
  

   white. 
  The 
  other 
  is 
  called 
  ' 
  ' 
  Fleshy, 
  ' 
  ' 
  and 
  is 
  of 
  

   a 
  pale 
  pink 
  throughout 
  the 
  whole 
  corolla. 
  Ad- 
  

   ding 
  these 
  twp 
  units 
  to 
  one 
  another, 
  we 
  get 
  the 
  

   original 
  dark 
  red 
  of 
  the 
  wild 
  type, 
  and 
  it 
  may 
  be 
  

   briefly 
  stated 
  here, 
  that 
  the 
  way 
  of 
  effecting 
  

   such 
  an 
  addition 
  is 
  given 
  us 
  in 
  the 
  crossing 
  of 
  

   the 
  "Fleshy" 
  and 
  the 
  " 
  Delila 
  " 
  variety, 
  

   the 
  hybrid 
  showing 
  the 
  two 
  colors 
  and 
  return- 
  

   ing 
  thereby 
  to 
  the 
  old 
  prototype. 
  

  

  Other 
  cases 
  of 
  compound 
  flower 
  colors 
  or 
  of 
  

   color 
  patterns 
  might 
  be 
  given 
  as 
  in 
  the 
  Mimulus 
  

   and 
  the 
  poppy, 
  and 
  in 
  most 
  of 
  these 
  cases 
  some 
  

   varieties 
  are 
  to 
  be 
  seen 
  in 
  our 
  gardens 
  which 
  

   show 
  only 
  the 
  single 
  constituents 
  of 
  the 
  group.
