  three 
  different 
  elements,

  statements

  of

  and 
  Hudson's-bay, 
  

   Cult, 
  1773. 
  by 
  Mr. 
  James 
  Gordon, 
  

  

  .Jhernald* 
  has 
  properly 
  discussed 
  the 
  status 
  of 
  the 
  two 
  native 
  

   specimens 
  covered 
  by 
  the 
  description. 
  Having 
  previously 
  dis- 
  

   cussed 
  the 
  matter 
  with 
  him, 
  the 
  author 
  agreed 
  that 
  the 
  name 
  

   must 
  be 
  apphed 
  to 
  the 
  Hudson 
  Bay 
  specimen, 
  rather 
  than 
  the 
  

   Newfoundland 
  one, 
  for 
  the 
  plant 
  is 
  named 
  the 
  "Hudson 
  Bay 
  

   Rose,"* 
  and 
  the 
  hypanthium 
  Is 
  described 
  as 
  glabrous. 
  Prior 
  to 
  

   this 
  discussion 
  with 
  Professor 
  Fernald, 
  I 
  had 
  held 
  the 
  opinion 
  that 
  

   the 
  Newfoundland 
  plant 
  should 
  be 
  regarded 
  as 
  the 
  type, 
  partly 
  

   because 
  Solander, 
  who 
  prepared 
  part 
  of 
  the 
  manuscript 
  for 
  the 
  

   first 
  edition 
  of 
  Alton's 
  Hortus 
  Kewensis, 
  had 
  in 
  manuscript 
  

   called 
  this 
  R. 
  blanda 
  and 
  the 
  Hudson 
  Bay 
  shrub 
  R. 
  blanda 
  jS; 
  and 
  

   partly 
  because 
  R. 
  blanda 
  is 
  described 
  as 
  glabrous. 
  I 
  therefore 
  

   adopted 
  the 
  name 
  R. 
  Solanderi 
  Tratt. 
  for 
  the 
  shrub 
  usually 
  called 
  

   R. 
  blanda, 
  the 
  species 
  with 
  pubescent 
  leaves. 
  Having 
  conceded 
  

   to 
  Fernald's 
  argument, 
  I 
  have 
  left 
  R. 
  blanda 
  as 
  Interpreted 
  by 
  

   LIndley. 
  If 
  the 
  name 
  R. 
  blanda 
  is 
  applied 
  to 
  the 
  Newfoundland 
  

   plant, 
  it 
  would 
  become 
  a 
  synonym 
  of 
  R.

  the 
  pubescence 
  of 
  the 
  lower 
  surface 
  of 
  the 
  leaves 
  is 
  

  

  acicularioides. 
  In 
  

  

  specimens 
  the 
  leaflets 
  are 
  more 
  

  

  the 
  hypanthium 
  more 
  elongate, 
  or 
  pear-shaped, 
  or 
  with 
  a 
  distinct 
  

   neck, 
  and 
  In 
  such 
  cases 
  the 
  specimens 
  are 
  probably 
  of 
  hybrid 
  origin, 
  

   i.e., 
  represent 
  R. 
  acicuhris

  In 
  the

  also 
  more 
  pubescent.
