  over 
  the 
  branches 
  in 
  sessile 
  buds, 
  which 
  appear 
  before 
  the 
  develope- 
  

   ment 
  of 
  the 
  leaves 
  ; 
  they 
  are 
  destitute 
  of 
  a 
  proper 
  calix 
  and 
  corolla. 
  

   The 
  involucrum 
  consists 
  of 
  nothing 
  more 
  than 
  the 
  four 
  innermost 
  

   greenish 
  decussated 
  bud 
  scales, 
  the 
  lower 
  ones 
  being 
  smaller, 
  sphace- 
  

   lous 
  and 
  more 
  numerous. 
  The 
  flowers 
  are 
  aggregated 
  by 
  six, 
  eight, 
  

   or 
  more 
  together, 
  and 
  the 
  stamina, 
  four 
  to 
  six 
  in 
  number, 
  are 
  articu- 
  

   lated 
  to 
  a 
  common 
  receptacular 
  pedicell, 
  and 
  exserted 
  beyond 
  the 
  in- 
  

   volucrum, 
  perfecting 
  at 
  different 
  times 
  ; 
  anthers 
  roundish, 
  adnate 
  to 
  

   the 
  filaments. 
  The 
  singular 
  structure 
  of 
  the 
  flowers, 
  notwithstanding 
  

   the 
  disparity 
  of 
  the 
  fruit, 
  renders 
  this 
  plant 
  inseparable 
  from 
  the 
  order 
  

   of 
  Euphorbia. 
  — 
  Hab. 
  In 
  the 
  inundated 
  lands 
  of 
  the 
  Ohio, 
  Mississippi, 
  

   Arkansas 
  and 
  Red 
  rivers.

  Foliis

   latis 
  ; 
  fructibus 
  oblongis 
  parvulis. 
  — 
  Hab. 
  In 
  the 
  prairies 
  of 
  Red 
  river. 
  

   — 
  Obs. 
  A 
  low 
  and 
  very 
  much 
  branched 
  shrub, 
  almost 
  similar 
  to 
  a 
  

   sloe 
  bush; 
  branchlets 
  and 
  leaves 
  pubescent; 
  leaves 
  obtuse 
  or 
  acute, 
  

   opposite 
  ; 
  fruit 
  cylindric-oblong, 
  black 
  and 
  saccharine 
  to 
  the 
  taste, 
  upon 
  

   longish 
  peduncles, 
  and 
  scarcely 
  half 
  as 
  large 
  as 
  that 
  of 
  F. 
  acuminata, 
  

   the 
  nut 
  striated 
  and 
  a 
  little 
  oblique, 
  the 
  shell 
  flexible 
  ; 
  embryo 
  flat 
  

   and 
  erect, 
  immersed 
  in 
  the 
  centre 
  of 
  a 
  cartilaginous 
  albumen. 
  As 
  this 
  

   plant 
  is 
  now 
  cultivated 
  in 
  the 
  gardens 
  of 
  Messrs 
  Landreth 
  and 
  Bartram, 
  

   I 
  imagine 
  it 
  to 
  be 
  the 
  same 
  which 
  Mr 
  Pursh 
  saw 
  among 
  the 
  specimens 
  

   collected 
  by 
  Lyons, 
  which 
  I 
  can 
  by 
  no 
  means 
  reconcile 
  to 
  the 
  descrip- 
  

   tion 
  of 
  F. 
  ligustrina 
  of 
  Michaux.
