  — 
  As 
  the 
  relative 
  number 
  of 
  parts, 
  etc., 
  are 
  

   not 
  given 
  in 
  descriptions 
  of 
  S. 
  elongata 
  and 
  some 
  of 
  its 
  allies, 
  as 
  S. 
  serotina, 
  S. 
  

   Canadensis, 
  S. 
  gigantca, 
  etc., 
  it 
  was 
  deemed 
  best 
  to 
  give 
  ample 
  details, 
  if 
  need 
  

   be, 
  for 
  comparison 
  or 
  amendment. 
  Although 
  placed 
  under 
  S. 
  elongata 
  (Nutt.) 
  

   it 
  is 
  by 
  no 
  means 
  " 
  obscurely 
  triplinerved," 
  for 
  the 
  triple 
  nerves 
  and 
  midrib 
  are 
  

   conspicuously 
  and 
  sharply 
  prominent 
  beneath 
  ; 
  the 
  expanding 
  base 
  of 
  the 
  mid- 
  

   rib 
  is 
  strongly 
  3-nerved 
  and 
  thence 
  decurrent 
  along 
  the 
  stem 
  ; 
  heads 
  remarkably 
  

   small 
  (little 
  more 
  than 
  a 
  line 
  in 
  diameter,) 
  for 
  such 
  a 
  large 
  and 
  vigoroas 
  plant 
  ; 
  

   involucral 
  scales 
  more 
  than 
  20 
  (15 
  to 
  22) 
  ; 
  rays 
  numerous, 
  exsert 
  but 
  indis- 
  

   tinct, 
  except 
  by 
  careful 
  inspection 
  ,• 
  or 
  in 
  general, 
  the 
  exceeding 
  number 
  of 
  

   parts, 
  though 
  common 
  to 
  all, 
  attain 
  to 
  the 
  rank 
  of 
  distinctive 
  characteristics 
  

   where 
  disparity 
  is 
  so 
  great 
  ; 
  added 
  to 
  special 
  points, 
  it 
  is 
  thought 
  to 
  entitle 
  it 
  

   to 
  the 
  consideration, 
  at 
  least, 
  of 
  a 
  variety. 
  It 
  is 
  hoped 
  some 
  simpler 
  and 
  more 
  

   generous 
  revision 
  may 
  be 
  adopted, 
  which, 
  will 
  include 
  all 
  these 
  in 
  one, 
  with 
  due 
  

   recognition 
  of 
  sub-sjoecies 
  and 
  varieties.
