NEPENTHACEiE. 



The pitcher plants are known to the Malays as " Poko 

 Priok Krah," (ape's cups). The steins of the stouter 

 kinds are used for binding fences. They always occur 

 in open country, borders of woods, etc., and are absent 

 from dense jungle. 



X. ampullaria Jack. A common kind with the pitchers in whorls 

 often sunk in the ground, pitchers green, or more or less 

 spotted with purple. I once found a plant with ivory 

 white pitchers. Tanglin, Chan Chu Kang, etc.

 over Singapore.
