the shrub described by Mr. Kingdon. What he terms the “ large 
bulbous root" is probably the fleshy stem. 
Little appears to be known about the barabanja except that it is 
a tree of fifty feet in height. It Mcd be conjectured thai it is an

the latex which drips from the ends and coagulating it with 
lemon juice or with bruised 1 fruits of the tamarind. The latex is
