  — 
  In 
  denu- 
  

   dated 
  places 
  in 
  the 
  open 
  prairies 
  ; 
  common, 
  and 
  rather 
  larger 
  than 
  the 
  

   Missouri 
  plant. 
  

  

  1. 
  Anthopogon 
  lepturoides 
  (Andropogon 
  ambiguum, 
  Michaux). 
  

   Racemis 
  e 
  basi 
  floriferis 
  ; 
  calicibus 
  subbifloris 
  ; 
  floribus 
  nudis 
  longe 
  aris- 
  

   tatis; 
  foliis 
  ovato-lanceolatis. 
  — 
  Hab. 
  Near 
  the 
  Cadron, 
  in 
  open 
  woods. 
  — 
  

   Obs. 
  In 
  the 
  most 
  perfect 
  natural 
  specimens 
  the 
  calix 
  contains 
  two 
  

   flowers 
  besides 
  the 
  rudiment.

  calicibus 
  

   unifloris; 
  valvula 
  exteriore 
  ad 
  marginem 
  barbata, 
  arista 
  brevissima;

  brevibus. 
  — 
  Hab. 
  In 
  shrubby 
  prairies 
  near 
  the 
  banks 
  

   of 
  the 
  Arkansas. 
  1 
  first 
  detected 
  this 
  very 
  distinct 
  species 
  on 
  the 
  

   bushy 
  margins 
  of 
  swamps 
  in 
  Sussex 
  county, 
  Delaware, 
  a 
  few 
  miles 
  

   from 
  Lewistown, 
  in 
  September 
  1818. 
  — 
  Obs. 
  Perennial; 
  culm 
  slender, 
  

   below 
  the 
  panicle, 
  as 
  in 
  the 
  other 
  species, 
  rather 
  crowded 
  with 
  some- 
  

   what 
  distichally 
  disposed 
  leaves, 
  which 
  are, 
  however, 
  much 
  shorter 
  and 
  

   narrower 
  ; 
  panicle 
  virgate, 
  and 
  the 
  branchlets 
  very 
  slenderly 
  filiform 
  

   (about 
  fifteen 
  to 
  twenty, 
  in 
  the 
  preceding 
  species 
  often 
  thirty), 
  pro- 
  

   ducing 
  flowers 
  only 
  towards 
  the 
  summit 
  ; 
  flowers 
  minutely 
  pedicellate, 
  

   appressed 
  to 
  the 
  rachis; 
  calix 
  acuminate, 
  scabrous, 
  1 
  -flowered; 
  corolla 
  

   glume 
  lanceolate, 
  the 
  margin 
  of 
  the 
  outer 
  glume 
  bearded 
  ; 
  the 
  awn 
  

   scarcely 
  half 
  the 
  length 
  of 
  the 
  valve 
  ; 
  neutral 
  rudiment 
  setiform 
  and 
  

   included. 
  

  

  1. 
  Erianthus 
  alopecuroides. 
  2. 
  E. 
  contortus, 
  Baldwyn 
  in 
  Elliott's 
  

   Sketches 
  Bot. 
  Carol, 
  p. 
  40. 
  — 
  Hab. 
  On 
  shelving 
  rocks 
  along 
  the 
  banks 
  

   of 
  the 
  Arkansas. 
  

  

  1. 
  Andropogon 
  virginicum. 
  2. 
  A. 
  macrourum. 
  

  

  3. 
  A. 
  avenaceum. 
  — 
  This 
  species 
  is 
  very 
  generally 
  considered 
  the 
  

  

  been 
  omitted 
  ; 
  for 
  which 
  casualty 
  I 
  conceive 
  myself 
  by 
  no 
  means 
  deserving 
  of 
  the 
  injurious 
  

   sarcasms 
  which 
  it 
  has 
  occasioned. 
  In 
  the 
  detailed 
  description 
  of 
  the 
  same 
  plant 
  I 
  had 
  also 
  

   ventured 
  to 
  consider 
  the 
  third 
  valve 
  of 
  the 
  corolla 
  as 
  a 
  neutral 
  rudiment 
  of 
  a 
  second 
  flower, 
  an 
  

   inference 
  which 
  numerous 
  analogies 
  in 
  the 
  vegetable 
  kingdom, 
  and 
  particularly 
  in 
  the 
  Grami- 
  

   neae, 
  sufficiently 
  warrant 
  as 
  just 
  and 
  accurate. 
  In 
  the 
  genus 
  Panicum 
  this 
  abortion 
  of 
  the 
  

   sexual 
  organs 
  is 
  even 
  the 
  essential 
  character 
  of 
  the 
  genus. 
  But 
  to 
  answer 
  every 
  ill-natured 
  cavil 
  

   which 
  might 
  be 
  brought 
  against 
  the 
  descriptions 
  of 
  natural 
  objects, 
  or 
  to 
  expect 
  an 
  uniformity 
  

   of 
  conception, 
  any 
  more 
  than 
  in 
  the 
  characters 
  of 
  the 
  objects 
  themselves, 
  would 
  be 
  attempting 
  

   something 
  more 
  than 
  human 
  and 
  only 
  adding 
  folly 
  to 
  weakness.
