" Technically the fruit may be described as follows : Form broadly 

 obovoid, oval, or oblong-oval; size below medium to medium, weight 

 10 to 14 ounces, length 3* to 4 inches, breadth 3 to 3i inches; base 

 rounded to bluntly pointed, the stem inserted somewhat obliquely with- 

 out depression ; apex obliquely flattened, though not markedly so, slightly 

 depressed around the stigmatic point ; surface nearly smooth to lightly 

 pebbled, glossy purplish black in color, with numerous small to large 

 yellowish dots; skin rather thin, one-sixteenth of an inch or slightly
