  Species

  Oenothera

  tion 
  of 
  it 
  and 
  his 
  type 
  specimens 
  are 
  still 
  pre- 
  

   served 
  in 
  the 
  herbarium 
  of 
  the 
  Museum, 
  where 
  

   I 
  have 
  compared 
  them 
  with 
  the 
  plants 
  of 
  my 
  

   own 
  culture. 
  Shortly 
  afterwards 
  it 
  was 
  re- 
  

   named 
  by 
  Seringe, 
  in 
  honor 
  of 
  its 
  eminent 
  dis- 
  

   coverer, 
  whose 
  name 
  it 
  now 
  bears. 
  So 
  Lamarck 
  

   unconsciously 
  discovered 
  and 
  described 
  himself 
  

   the 
  plant, 
  which 
  after 
  a 
  century, 
  was 
  to 
  become 
  

   the 
  means 
  of 
  an 
  empirical 
  demonstration 
  of 
  his 
  

   far-reaching 
  views 
  on 
  the 
  common 
  origin 
  of 
  all 
  

   living 
  beings. 
  

  

  Oenothera 
  lamarckiana 
  is 
  considered 
  in 
  

   Europe 
  as 
  a 
  garden-plant, 
  much 
  prized 
  for 
  

   parks 
  and 
  ornamental 
  planting. 
  It 
  is 
  cultivated 
  

   by 
  seed-merchants 
  and 
  offered 
  for 
  sale. 
  It 
  has 
  

   escaped 
  from 
  gardens, 
  and 
  having 
  abundant 
  

   means 
  for 
  rapid 
  multiplication, 
  has 
  become 
  wild 
  

   in 
  many 
  places. 
  As 
  far 
  as 
  I 
  know 
  its 
  known 
  

   localities 
  are 
  small, 
  and 
  it 
  is 
  to 
  be 
  presumed 
  

   that 
  in 
  each 
  of 
  them 
  the 
  plant 
  has 
  escaped 
  sep- 
  

   arately 
  from 
  culture. 
  It 
  was 
  in 
  this 
  state 
  that 
  

   I 
  first 
  met 
  with 
  this 
  beautiful 
  species. 
  

  

  Lamarck's 
  evening-primrose 
  is 
  a 
  stately 
  

   plant, 
  with 
  a 
  stout 
  stem, 
  attaining 
  often 
  a 
  height 
  

   of 
  1.6 
  meters 
  and 
  more. 
  When 
  not 
  crowded 
  the 
  

   main 
  stem 
  is 
  surrounded 
  by 
  a 
  large 
  circle 
  of 
  

   smaller 
  branches, 
  growing 
  upwards 
  from 
  its 
  

   base 
  so 
  as 
  often 
  to 
  form 
  a 
  dense 
  bush. 
  These 
  

   branches 
  in 
  their 
  turn 
  have 
  numerous 
  lateral
