  also 
  been 
  appended 
  among 
  which 
  the 
  Flora 
  of 
  Missouri 
  by 
  Tracy 
  

   (24), 
  the 
  only 
  general 
  catalogue 
  for 
  the 
  state, 
  is 
  now 
  somewhat 
  in- 
  

   complete 
  and 
  out 
  of 
  date, 
  as 
  it 
  was 
  published 
  in 
  1885. 
  Among 
  local 
  

   and 
  county 
  floras 
  those 
  of 
  greatest 
  value 
  are 
  that 
  for 
  Columbia 
  and 
  

   vicinity 
  by 
  Daniels 
  (8) 
  ; 
  for 
  Jackson 
  county 
  by 
  Mackenzie 
  and 
  Bush 
  

   (14); 
  St. 
  Louis 
  and 
  vicinity 
  by 
  Eggert 
  (9), 
  Engelmann 
  (10), 
  Hus 
  (13), 
  

   and 
  the 
  Engelmann 
  Botanical 
  Club 
  (28). 
  The 
  southeastern 
  counties 
  

   have 
  been 
  discussed 
  by 
  Bush 
  (4) 
  and 
  Uphof 
  (25) 
  . 
  The 
  trees 
  and 
  shrubs 
  

   are 
  treated 
  by 
  Broadhead 
  (2), 
  Bush 
  (6) 
  and 
  anonymously 
  (29). 
  A 
  

   few 
  miscellaneous 
  papers 
  of 
  interest 
  have 
  been 
  included 
  in 
  addition 
  

   to 
  those 
  mentioned. 
  

  

  There 
  is 
  no 
  doubt 
  that 
  the 
  number 
  of 
  new 
  plants 
  here 
  added 
  to 
  the 
  

   flora 
  of 
  Missouri 
  is 
  small 
  in 
  comparison 
  with 
  those 
  that 
  will 
  be 
  found 
  

   when 
  extensive 
  general 
  collections 
  are 
  made. 
  The 
  Ozark 
  region 
  of 
  the 
  

   southwest 
  and 
  the 
  swampy 
  region 
  of 
  the 
  southeast 
  are 
  incompletely 
  

   known. 
  The 
  latter 
  region 
  may 
  be 
  worked 
  profitably 
  by 
  anyone 
  as 
  it 
  

   will 
  yield 
  important 
  data 
  bearing 
  on 
  many 
  interesting 
  problems 
  in 
  

   southern 
  and 
  northern 
  distribution.
