  Similarly 
  divided

   leaves 
  seem 
  to 
  have 
  occurred 
  more 
  often 
  in 
  the 
  

   wild

  and 
  cut-leaved 
  hazels 
  are 
  recorded 
  

   from 
  Eouen 
  in 
  France, 
  birches

  alders 
  from 
  

   Sweden

  Lapland, 
  where 
  both 
  are 
  said 
  to 
  

   have 
  been 
  met

  several

  The 
  

   purple 
  barberry 
  was 
  found 
  about 
  1830 
  by 
  Ber- 
  

   tin, 
  near 
  Versailles. 
  Weeping 
  varieties 
  of 
  

   ashes 
  were 
  found 
  wild 
  in 
  England 
  and 
  in 
  Ger- 
  

   many,

  broom-like 
  oaks, 
  Quercus

  are 
  recorded 
  from 
  Hessen- 
  

   Darmstadt, 
  Calabria, 
  the 
  Pyrenees 
  and

   localities.

  The 
  ' 
  ' 
  single-leaved 
  ; 
  ' 
  strawberry 
  is 
  a 
  variety 
  

   often 
  seen 
  in 
  botanical 
  gardens, 
  as 
  it 
  is 
  easily 
  

   propagated 
  by 
  its 
  runners. 
  It 
  was 
  discovered 
  

   wild 
  in 
  Lapland 
  at 
  the 
  time 
  of 
  Linnaeus, 
  and 
  

   appeared 
  afterwards 
  unexpectedly 
  in 
  a 
  nursery 
  

   near 
  Versailles. 
  This 
  happened 
  about 
  the 
  year 
  

   1760 
  and 
  Duchesne 
  tested 
  it 
  from 
  seeds 
  and 
  

   found 
  it 
  constant. 
  This 
  strain, 
  however, 
  seems 
  

   to 
  have 
  died 
  out 
  before 
  the 
  end 
  of 
  the 
  18th 
  cen- 
  

   tury. 
  In 
  a 
  picture 
  painted 
  by 
  Holbein 
  (1495- 
  

   1543), 
  strawberry 
  leaves 
  can 
  be 
  seen 
  agreeing 
  

   exactly 
  with 
  the 
  monophyllous 
  type. 
  The 
  va- 
  

   riety 
  may 
  thus 
  be 
  assumed 
  to 
  have 
  arisen 
  inde-
