The "Ipoh" Tree — Perak. 



The Resident of Perak having collected some of the juice of this 

 tree, it was sent to Kew, together with some of the leaves, for 

 identification. 



Sir Joseph Hooker was good enough to submit it to Professor 

 Oliver, who wrote as follows : — 



'"'The 'Ipoh' from Perak is either the Upas (antiaris toxicavia) 

 " or a close ally. Our specimens hardly differ, except in being 

 " more glabrous. 



" Griffith labels a specimen ' The small-leaved Epoo or Jackoon 

 ■'■ poison.' 



" He adds: ' Arsenic is mixed with the milk, which is said to be 

 '"'otherwise inert.' 



"The Perak specimens are without flower or fruit."' 



Professor Eixger, also, reports that the specimen sent " is abso- 

 lutely destitute of poisonous properties of any kind. It has in 

 ••fact no effect physiologically at all."
