214 GUTT^-PKODUCINU TBEES. 



I have never seen it growing on the plains, nor in fact lower 

 than 1,800 feet. 



It ripens its fruit in the month of February. 



The gutta is collected by felling the tree, ringing the bark, and 

 placing leaves, bamboos, &c, under it to catch the sap ; which is 

 afterwards boiled, and the natives often add salt to hasten its 

 coagulation. 



It is frequently adulterated with the gutta from Kayu Jelutong, 

 and two or three of the Bassias. 



The usual method of mixing them is to do so before the sap has 

 coagulated, as afterwards, owing to the high nelting point of Ta- 

 ban Puteh, they cannot be so easily and intimately combined. A 

 tree of ten inches in diameter, at four to five feet from the ground, 

 gave 2ft lloz. of fairly clean Grutta Percha. 



Getah Taban Puteh (Variety). 



This variety differs from the above, in having smaller leaves, and 

 in the shape of the fruit, which is longer in proportion to its breadth. 



I have found it growing on the hills at 2,300 feet elevation ; and 

 it ripens its fruit in the month of February. 



Getah Taban Chayer* Dicliopsia . 



This tree I have found growing at 600 feet above sea level ; and 

 it attains a large size. 



The bark is reddish-brown, and the wood is hard and white, with 

 a dark red centre. 



The backs of the leaves are, when young, of a golden brown, but 

 full grown ones are silvery. 



They have not the points of the leaves that are present in most 

 other varieties of Piehopsis. 



The flower, which appears about the middle of September, is pale 

 green, and very small. 



The corolla has a six-toothed limb, the teeth being nearly trian- 

 gular in shape, and so thin as to be almost transparent. 



* Chayer=liquid.
