  over 
  thirty 
  years 
  with 
  the 
  white 
  variety 
  of 
  the 
  

   yellow 
  foxglove 
  (Digitalis 
  parviflora). 
  

  

  White-flowered 
  varieties 
  of 
  perennial 
  garden- 
  

   plants 
  were 
  used 
  in 
  my 
  own 
  experiments. 
  I 
  

   bought 
  the 
  plants, 
  flowered 
  them 
  under 
  isolation 
  

   in 
  the 
  way 
  described 
  above, 
  gathered 
  the 
  seeds 
  

   from 
  each 
  individual 
  separately 
  and 
  sowed 
  them 
  

   in 
  isolated 
  groups, 
  keeping 
  many 
  hundreds 
  and 
  

   in 
  some 
  cases 
  above 
  a 
  thousand 
  plants 
  up 
  to 
  

   the 
  time 
  of 
  flowering. 
  Among 
  them 
  I 
  found 
  

   only 
  one 
  inconstant 
  variety, 
  the 
  white 
  form 
  of 
  

   the 
  yellow 
  columbine, 
  Aquilegia 
  chrysantha. 
  It 
  

   evidently 
  belonged 
  to 
  the 
  group 
  of 
  sporting 
  va- 
  

   rieties 
  already 
  referred 
  to. 
  All 
  others 
  came 
  ab- 
  

   solutely 
  true 
  to 
  type 
  without 
  any 
  exception. 
  The 
  

   species 
  experimented 
  with, 
  were 
  Campanula 
  

   persicifolia,Hyssopus 
  officinalis, 
  Lobelia 
  syphil- 
  

   itica, 
  Lychnis 
  chalcedonica, 
  Polemonium 
  dissec- 
  

   tum, 
  Salvia 
  sylvestris 
  and 
  some 
  others. 
  Tested 
  

   in 
  the 
  same 
  way 
  I 
  found 
  the 
  white 
  varieties 
  of 
  

   the 
  following 
  annual 
  plants 
  also 
  quite 
  true: 
  

   Chrysanthemum 
  coronarium, 
  Godetia 
  amoena, 
  

   Linum 
  usitatissimum, 
  Phlox 
  drummondi, 
  and 
  

   Silene 
  Armeria. 
  To 
  these 
  may 
  be 
  added 
  the 
  

   white 
  hemlock 
  stork 
  Vbill 
  (Er 
  odium 
  cicutarium 
  

   album) 
  which 
  grows 
  very 
  abundantly 
  in 
  some 
  

   parts 
  of 
  my 
  fatherland, 
  and 
  is 
  easily 
  recogniz- 
  

   able 
  by 
  its 
  pure 
  green 
  leaves 
  and 
  stems, 
  even 
  

   when 
  not 
  flowering. 
  I 
  cultivated 
  it 
  in 
  large 
  num-
