  The 
  

   species 
  are 
  naturally 
  grouped 
  into 
  those 
  with 
  small 
  fruits 
  and 
  

   those 
  with 
  large

  as

  An 
  interesting 
  gradation 
  in 
  

   stone

  is 
  to 
  be 
  noted.

  the

  flattened, 
  and 
  the

   rounded 
  and 
  prominent, 
  giving 
  a 
  furrowed 
  appearance 
  to 
  

   the 
  thin-fleshed 
  fruit 
  ; 
  in

  the 
  ridges 
  are 
  acute 
  and 
  

   prominent, 
  separated 
  by 
  broad
