  [ 
  December, 
  

  

  some 
  other 
  designation, 
  for 
  I 
  have 
  met 
  with 
  it 
  often 
  enough 
  

   to 
  look 
  upon 
  it 
  as 
  constant. 
  

  

  _ 
  There 
  was 
  one 
  feature 
  of 
  the 
  flowers 
  of 
  this 
  region 
  deserv- 
  

   ing 
  recognition, 
  as 
  it 
  especially 
  attracted 
  my 
  attention. 
  It 
  

   was 
  the 
  brightness 
  of 
  their 
  coloration 
  in 
  hues 
  belonging 
  to 
  

   the 
  redand 
  blue 
  series. 
  This 
  was 
  not 
  noticeable 
  in 
  the 
  yel- 
  

   low 
  series, 
  though 
  it 
  may 
  have 
  been 
  because 
  the 
  shades 
  of 
  

   yellow 
  are 
  not 
  so 
  varied 
  or 
  striking. 
  There 
  was 
  also 
  a 
  ten- 
  

   dency 
  in 
  white 
  flowers 
  to 
  become 
  pink, 
  or 
  show 
  some 
  tinge 
  

   ot 
  color, 
  of 
  which 
  examples 
  have 
  been 
  given. 
  The 
  familiar 
  

   1 
  eds, 
  pmks 
  and 
  purples 
  of 
  the 
  flowers 
  at 
  home 
  were 
  more 
  

   deeply 
  shaded, 
  and 
  so 
  of 
  the 
  blues 
  and 
  violets, 
  or 
  any 
  inter- 
  

   mediate 
  hues. 
  Though 
  inclined 
  to 
  ascribe 
  this 
  to 
  a 
  northerly 
  

   iatitude,_ 
  since 
  it 
  is 
  known 
  to 
  be
