﻿Origin 
  of 
  Peloric 
  Toadflax 
  467 
  

  

  wards 
  in 
  the 
  vicinity 
  of 
  Berlin, 
  as 
  stated 
  by 
  

   Ratzeburg, 
  1825. 
  Many 
  other 
  localities 
  have 
  

   since 
  been 
  indicated 
  for 
  it 
  in 
  Europe, 
  and 
  in 
  my 
  

   own 
  country 
  some 
  have 
  been 
  noted 
  of 
  late, 
  as 
  

   for 
  instance 
  near 
  Zandvoort 
  in 
  1874 
  and 
  near 
  

   Oldenzaal 
  in 
  1896. 
  In 
  both 
  these 
  last 
  named 
  

   cases 
  the 
  peloric 
  form 
  arose 
  spontaneously 
  in 
  

   places 
  which 
  had 
  often 
  been 
  visited 
  by 
  botanists 
  

   before 
  the 
  recorded 
  appearance, 
  and 
  therefore, 
  

   without 
  any 
  doubt, 
  they 
  must 
  have 
  been 
  pro- 
  

   duced 
  directly 
  and 
  independently 
  by 
  the 
  ordi- 
  

   nary 
  species 
  which 
  grows 
  in 
  the 
  locality. 
  The 
  

   same 
  holds 
  good 
  for 
  other 
  occurrences 
  of 
  it. 
  

  

  In 
  many 
  instances 
  the 
  variety 
  has 
  been 
  re- 
  

   corded 
  to 
  disappear 
  after 
  a 
  certain 
  lapse 
  of 
  

   time, 
  the 
  original 
  specimens 
  dying 
  out 
  and 
  no 
  

   new 
  ones 
  being 
  produced. 
  Linaria 
  is 
  a 
  peren- 
  

   nial 
  herb, 
  multiplying 
  itself 
  easily 
  by 
  buds 
  grow- 
  

   ing 
  on 
  the 
  roots, 
  but 
  even 
  with 
  this 
  means 
  of 
  

   propagation 
  its 
  duration 
  seems 
  to 
  have 
  definite 
  

   limits. 
  

  

  There 
  is 
  one 
  other 
  important 
  point 
  arguing 
  

   strongly 
  for 
  the 
  independent 
  appearance 
  of 
  the 
  

   peloric 
  form 
  in 
  its 
  several 
  localities. 
  It 
  is 
  the 
  

   difficulty 
  of 
  fertilization 
  and 
  the 
  high 
  degree 
  of 
  

   sterility, 
  even 
  if 
  artificially 
  pollinated. 
  Bees 
  and 
  

   humble-bees 
  are 
  unable 
  to 
  crawl 
  into 
  the 
  nar- 
  

   row 
  tubular 
  flowers, 
  and 
  to 
  bring 
  the 
  fertilizing 
  

   pollen 
  to 
  the 
  stigma.
