  same 
  as 
  the 
  A. 
  nutans 
  $ 
  it 
  appears, 
  however, 
  to 
  be 
  sufficiently 
  distinct, 
  

   and 
  occupies 
  a 
  more 
  northern 
  range. 
  The 
  panicle 
  of 
  the 
  A. 
  avenaceum 
  

   of 
  Michaux 
  is 
  erect 
  and 
  fewer 
  flowered, 
  the 
  flowers 
  are 
  larger 
  and 
  the 
  

   awn 
  about 
  naif 
  the 
  length 
  of 
  that 
  of 
  A. 
  nutans, 
  the 
  rufescent 
  colour 
  

   also 
  described 
  by 
  Michaux 
  is 
  very 
  constant 
  and 
  belongs 
  to 
  the 
  pubes- 
  

   cence, 
  which 
  in 
  the 
  other 
  species 
  is 
  yellowish. 
  A. 
  avenaceum 
  is 
  the 
  

   A. 
  ciliatus 
  of 
  Mr 
  Elliott. 
  Although 
  these 
  two 
  species 
  differ 
  in 
  habit, 
  

   yet 
  they 
  agree 
  in 
  structure 
  precisely 
  with 
  the 
  genus 
  Andropogon. 
  I 
  

   can 
  perceive 
  no 
  possible 
  reason 
  to 
  refer 
  A. 
  nutans 
  to 
  the 
  genus 
  An- 
  

   thisteria, 
  as 
  has 
  been 
  done 
  by 
  Persoon.

  1. 
  Zizania

  2. 
  Z. 
  miiiacea. 
  This 
  species 
  is 
  to 
  me 
  very 
  

   rare. 
  I 
  first 
  recognized 
  it 
  near 
  to 
  the 
  Great 
  Salt 
  river 
  of 
  the 
  Arkansas. 
  

   Although 
  there 
  is 
  an 
  admixture 
  of 
  fertile 
  and 
  infertile 
  flowers, 
  yet 
  the 
  

   former, 
  as 
  in 
  the 
  common 
  species, 
  pretty 
  generally 
  occupy 
  the 
  summit 
  

   of 
  the 
  panicle.
