  duced 
  in 
  the 
  nursery 
  of 
  Mr. 
  Chr. 
  Lorenz 
  in 
  

   Erfurt, 
  and 
  are 
  now 
  for 
  sale, 
  the 
  seeds 
  being 
  

   guaranteed 
  to 
  yield 
  a 
  large 
  proportion 
  of 
  

   peloric 
  individuals. 
  The 
  peloric 
  form 
  in 
  this 
  

   case 
  appeared 
  at 
  once, 
  but 
  was 
  not 
  isolated, 
  and 
  

   was 
  left 
  free 
  to 
  visiting 
  insects, 
  which 
  of 
  course 
  

   crossed 
  it 
  with 
  the 
  surrounding 
  varieties. 
  

   Without 
  doubt 
  the 
  existence 
  of 
  two 
  color-varie- 
  

   ties 
  of 
  the 
  peloric 
  type, 
  one 
  of 
  a 
  very 
  dark 
  red, 
  

   indicating 
  the 
  " 
  Black 
  prince 
  : 
  variety 
  as 
  the 
  

   pollen-parent, 
  and 
  the 
  other 
  with 
  a 
  white 
  tube 
  

   of 
  the 
  corolla, 
  recalling 
  the 
  form 
  known 
  as 
  

   " 
  Delila," 
  is 
  due 
  to 
  these 
  crossings. 
  I 
  had 
  last 
  

   year 
  (1903) 
  a 
  large 
  lot 
  of 
  plants, 
  partly 
  normal 
  

   and 
  partly 
  peloric, 
  but 
  evidently 
  of 
  hybrid 
  

   origin, 
  from 
  seeds 
  from 
  this 
  nursery, 
  showing 
  

   moreover 
  all 
  intermediate 
  steps 
  between 
  nearly 
  

   wholly 
  peloric 
  individuals 
  and 
  apparently 
  nor- 
  

   mal 
  ones. 
  I 
  have 
  saved 
  the 
  seeds 
  of 
  the 
  iso- 
  

   lated 
  types 
  and 
  before 
  seeing 
  the 
  flowers 
  of 
  

   their 
  offspring, 
  nothing 
  can 
  be 
  said 
  about 
  the 
  

   purity 
  and 
  constancy 
  of 
  the 
  type, 
  when 
  freed 
  

   from 
  hybrid 
  admixtures. 
  The 
  peloric 
  snap- 
  

   dragon 
  has 
  five 
  small 
  unequal 
  spurs 
  at 
  the 
  base 
  

   of 
  its 
  long 
  tube, 
  and 
  in 
  this 
  respect 
  agrees 
  with 
  

   the 
  peloric 
  toad-flax. 
  

  

  Other 
  pelories 
  are 
  terminal 
  and 
  quite 
  regular, 
  

   and 
  occur 
  in 
  some 
  species 
  of 
  Linaria, 
  where 
  I 
  

   observed 
  them 
  in 
  Linaria 
  dalmatica.
