  In

  it

  more 
  common 
  than

  extends 
  as 
  far

  as 
  

   central 
  New

  It 
  is 
  the

  This 
  species 
  is 
  probably 
  most 
  closely 
  related 
  to 
  i?. 
  virginiana 
  

   but 
  differs 
  in 
  the 
  smaller 
  and 
  less 
  numerous 
  flowers, 
  the 
  obovoid 
  

   fruit 
  acute 
  at 
  the 
  base, 
  the 
  smaller, 
  thinner, 
  and 
  not 
  shining 
  

   leaflets. 
  It 
  may 
  be 
  the 
  same 
  as 
  R. 
  acuminata 
  Raf., 
  but 
  the 
  

   leaflets 
  are 
  by 
  no 
  means 
  "acuminate," 
  and 
  the 
  distribution, 
  as 
  

   far 
  as 
  known, 
  is 
  quite 
  different. 
  The 
  following
