  Mr. 
  J. 
  Donnell 
  Smith 
  identified 
  these 
  specimens 
  with 
  Bentham's 
  above 
  

   named 
  species. 
  This, 
  however, 
  seems 
  to 
  have 
  larger 
  leaves, 
  with 
  7 
  to 
  19 
  

   almost 
  sessile 
  leaflets, 
  while 
  in 
  Beam's 
  specimens 
  these 
  are 
  9 
  to 
  11 
  and 
  petiolu- 
  

   late. 
  The 
  other 
  characters 
  seem 
  to 
  agree.

  Several 
  species 
  may 
  be 
  included 
  under 
  this 
  name. 
  According 
  to 
  Bentham, 
  

  

  it 
  is 
  a 
  tree; 
  Tonduz 
  describes 
  it 
  as 
  a 
  shrub 
  (arbrisseau) 
  ; 
  while 
  H. 
  H. 
  Smith 
  

  

  says 
  it 
  is 
  a 
  "twining 
  plant, 
  reaching 
  30 
  feet, 
  with 
  a 
  prickly 
  main 
  stem 
  and 
  2 
  

  

  inches 
  or 
  more 
  in 
  diameter." 
  In 
  my 
  own 
  notes, 
  no. 
  3834 
  is 
  described 
  as 
  "a 
  

  

  shrubby 
  vine, 
  with 
  white 
  flowers," 
  and 
  no. 
  6613, 
  as 
  a 
  small 
  tree 
  branching 
  from
