  Nearly 
  

   allied 
  to 
  P. 
  canadensis, 
  of 
  which 
  it 
  possesses 
  the 
  entire 
  aspect, 
  but 
  the 
  

   flowers 
  and 
  seeds 
  are 
  very 
  much 
  smaller, 
  and 
  indeed 
  altogether 
  dis- 
  

   tinct. 
  Doctor

  D. 
  Greene 
  found 
  this 
  species 
  in 
  Cuba, 
  and 
  Doctor 
  

   Little 
  discovered 
  it 
  in 
  the 
  vicinity 
  of 
  New 
  Orleans.

  Obs. 
  The 
  Panicum 
  milium 
  and 
  P. 
  Italicum 
  deserve 
  to 
  be 
  cultivated 
  

   in 
  the 
  warmer 
  states 
  and 
  territories 
  of 
  the 
  union, 
  particularly 
  where 
  

   wheat 
  is 
  found 
  not 
  to 
  succeed, 
  as 
  is 
  the 
  case 
  in 
  the 
  Arkansas 
  territory, 
  

   and 
  as 
  I 
  have 
  understood 
  also 
  in 
  the 
  warmer 
  parts 
  of 
  Tennessee 
  or 
  

   Kentucky. 
  In 
  Africa 
  and 
  tropical 
  America 
  the 
  Panicum 
  jumentorum, 
  

   called 
  Guinea 
  grass, 
  is 
  also 
  an 
  object 
  of 
  cultivation.
