   Obs. 
  Perennial. 
  Stem 
  erect, 
  low, 
  and 
  considerably 
  branched, 
  hex- 
  

   angular, 
  and 
  on 
  two 
  of 
  the 
  sides 
  grooved, 
  sometimes 
  striking 
  out 
  roots 
  

   from 
  its 
  base 
  ; 
  leaves 
  in 
  full 
  grown 
  plants 
  from 
  one 
  to 
  two 
  inches 
  wide, 
  

   and 
  five 
  or 
  six 
  inches 
  long, 
  upon 
  longish 
  petioles, 
  and 
  minutely 
  and 
  

   unequally 
  pubescent 
  ; 
  floral 
  branchlets 
  axillary 
  and 
  terminal, 
  the 
  clus- 
  

   ters 
  subsessile, 
  irregularly 
  3 
  to 
  6-flowered 
  ; 
  bracts 
  concealing 
  the 
  calix, 
  

   which 
  is 
  simple 
  and 
  very 
  small, 
  with 
  subulate 
  segments 
  ; 
  corolla 
  bila- 
  

   biate, 
  pale 
  violet 
  purple, 
  rather 
  small, 
  lobes 
  oblong, 
  undivided, 
  reflected, 
  

   and 
  almost 
  equal 
  in 
  magnitude, 
  the 
  upper 
  slightly 
  tridentate 
  at 
  the 
  

   extremity 
  and 
  maculate 
  at 
  the 
  base, 
  the 
  lower 
  2-toothed, 
  the 
  tube 
  

   compressed 
  and 
  contorted 
  ; 
  filaments 
  two, 
  diantheriferous 
  ; 
  style 
  undi- 
  

   vided 
  ; 
  capsule 
  suboval, 
  mucronulate, 
  sessile 
  and 
  compressed, 
  the 
  valves 
  

   membranaceous, 
  attached 
  to 
  a 
  curved 
  cartilaginous 
  border, 
  which 
  

   springing 
  apart 
  at 
  the 
  summit, 
  becomes 
  straight, 
  divides 
  the 
  valves 
  

   in 
  the 
  centre 
  and 
  separates 
  them 
  from 
  their 
  base, 
  so 
  as 
  to 
  present 
  an 
  

   appearance 
  not 
  very 
  dissimilar 
  to 
  the 
  blades 
  of 
  a 
  pair 
  of 
  shears 
  ; 
  reti- 
  

   naculum 
  divided, 
  springing

  — 
  On 
  the 
  banks 
  of 
  the 
  Mississippi, 
  near 
  the 
  set- 
  

   tlement 
  called 
  the 
  Big 
  Prairie, 
  a 
  few 
  miles 
  below 
  New 
  Madrid, 
  but 
  

   apparently 
  only 
  naturalized. 
  I 
  have 
  since 
  observed 
  this 
  tree 
  truly 
  

   indigenous 
  on 
  the 
  banks 
  of 
  the 
  Chatahoochee, 
  near 
  Columbus 
  in 
  Geor- 
  

   gia, 
  and 
  pretty 
  frequent 
  in 
  West 
  Florida 
  and 
  Lower 
  Alabama.
