  both 
  seasons 
  were 
  sown 
  on 
  a 
  large 
  scale. 
  Both 
  

   the 
  first 
  and 
  the 
  succeeding 
  generations 
  of 
  

   the 
  offspring 
  of 
  the 
  original 
  plant 
  caine 
  true 
  

   without 
  any 
  exception. 
  Intermediates 
  are 
  

   often 
  found 
  in 
  hybrid 
  cultures, 
  and 
  in 
  them 
  the 
  

   character 
  is 
  a 
  very 
  variable 
  one, 
  but 
  as 
  yet 
  they 
  

   were 
  not 
  met 
  with 
  in 
  progeny 
  of 
  this 
  mutant. 
  

   All 
  these 
  plants 
  were 
  exactly 
  like 
  0. 
  biennis, 
  

   with 
  the 
  single 
  exception 
  of 
  their 
  petals. 
  

  

  Epilobium 
  hirsutum 
  cruciatum 
  was 
  discov- 
  

   ered 
  by 
  John 
  Easor 
  near 
  Woolpit, 
  Bury 
  St. 
  Ed- 
  

   munds, 
  in 
  England. 
  It 
  flowered 
  in 
  one 
  spot, 
  

   producing 
  about 
  a 
  dozen 
  stems, 
  among 
  large 
  

   quantities 
  of 
  the 
  parent-species, 
  which 
  is 
  very 
  

   common 
  there, 
  as 
  it 
  is 
  elsewhere 
  in 
  Europe. 
  

   This 
  species 
  is 
  a 
  perennial, 
  multiplying 
  itself 
  by 
  

   underground 
  runners, 
  and 
  the 
  stems 
  of 
  the 
  

   new 
  variety 
  were 
  observed 
  to 
  stand 
  so 
  close 
  to 
  

   each 
  other 
  that 
  they 
  might 
  be 
  considered 
  as 
  the 
  

   shoots 
  of 
  one 
  individual. 
  In 
  this 
  case 
  this 
  spec- 
  

   imen 
  might 
  probably 
  be 
  the 
  original 
  mutant, 
  as 
  

   the 
  variety 
  had 
  not 
  been 
  seen 
  on 
  that 
  spot 
  in 
  

   previous 
  years, 
  even 
  as 
  it 
  has 
  not 
  been 
  found 
  

   elsewhere 
  in 
  the 
  vicinity. 
  

  

  Intermediates 
  were 
  not 
  observed, 
  though 
  the 
  

   difference 
  is 
  a 
  very 
  striking 
  one. 
  In 
  the 
  cru- 
  

   ciate 
  flowers 
  the 
  broad 
  and 
  bright 
  purple 
  petals 
  

   seem 
  at 
  first 
  sight 
  to 
  be 
  wholly 
  wanting. 
  They 
  

   are 
  too 
  weak 
  to 
  expand 
  and 
  to 
  reflex 
  the 
  calyx
