  This 
  and 
  the 
  preceding 
  species 
  have 
  been 
  discussed 
  by 
  their 
  

   author,* 
  and 
  nothing 
  more 
  needs 
  to 
  be 
  added.

  This 
  is 
  the 
  earliest 
  name 
  for 
  the 
  Cinnamon 
  Rose. 
  Linnaeus 
  

   probably 
  included 
  in 
  the 
  original 
  description 
  two 
  different 
  species,

  latter 
  species. 
  It 
  is 
  evident 
  that 
  Linnaeus 
  principally 
  had 
  in 
  

  

  m 
  

  

  namon 
  Rose. 
  

  

  Crepinf 
  has 
  shown 
  that 
  the 
  original 
  Rosa 
  cinnamomea 
  L., 
  

   of 
  the 
  first 
  edition 
  of 
  the 
  Species 
  Plantarum, 
  which 
  was 
  based 
  

   wholly 
  on 
  a 
  plant 
  from 
  Switzerland 
  and 
  described 
  by 
  Haller 
  and 
  

   Bauhin, 
  is 
  the 
  same 
  as 
  R. 
  pendulina 
  L. 
  In 
  the 
  first 
  edition 
  

   Linnaeus 
  gives 
  as 
  a 
  synonym 
  under 
  R. 
  cinnamomea, 
  "Rosa 
  

   sylvestris, 
  odoratissimo 
  rubro 
  flore. 
  Bank. 
  pin. 
  483." 
  Under 
  

   the 
  same 
  name, 
  in 
  the 
  second 
  edition, 
  he 
  cited, 
  "Rosa, 
  odore 
  

   cinnamomi, 
  simplex. 
  Bauh. 
  pin. 
  483," 
  which 
  shows 
  that 
  R. 
  cin- 
  

   namomea 
  I., 
  of 
  the 
  first 
  edition 
  was 
  not 
  the 
  same 
  as 
  that 
  of 
  the 
  

   second. 
  The 
  first 
  was 
  evidently 
  what 
  in 
  the 
  tenth 
  edition 
  of 
  his 
  

   Systema 
  and 
  in 
  the 
  second 
  edition 
  of 
  his 
  Species 
  Plantarum 
  is 
  

   called 
  R. 
  alpina, 
  which 
  is 
  the 
  same 
  as 
  R. 
  pendulina 
  L. 
  

  

  The 
  R. 
  cinnamomea 
  of 
  the 
  second 
  edition 
  is 
  the 
  plant 
  usually 
  

   known 
  under 
  that 
  name. 
  As 
  stated 
  before, 
  the 
  oldest 
  name 
  of 
  this 
  

   is 
  evidently 
  R. 
  spinosissima 
  L. 
  Not 
  that 
  that 
  name 
  should 
  be 
  

   entirely 
  equivalent 
  to 
  R. 
  cinnamomea 
  of 
  the 
  second 
  edition, 
  for 
  

   Linnaeus 
  evidently 
  had 
  two 
  species 
  confused. 
  He 
  gave 
  two 
  

   references 
  under 
  it, 
  one 
  to 
  his 
  Flora 
  Suecica 
  and 
  the 
  other 
  to 
  

  

  Pinax 
  

  

  spinosissima 
  

  

  understood, 
  i.e., 
  a 
  form 
  of 
  R. 
  pimpinellijolia; 
  but 
  the 
  former 
  

   must 
  be 
  something 
  else.

  pimpinellifolia 
  is 
  not 
  found, 
  even 
  as 
  

   an 
  escape, 
  in 
  the 
  part 
  of 
  Sweden 
  where 
  Linnaeus 
  reported 
  his 
  R. 
  

   spinosissima.
