$8 NOTES ON GUTTA PEKCHA. 



Order Apocynacce, Genus Wilhtghbeia ( ? ) 

 Urceola Elastica (?) 



1. Manungan Pulau or Boiiar, i. e., Manungan proper. 



2. „ Bujok ( Langaying) 



3. „ Manga ( light coloured bark) 



4. „ „ (dark „ „ ) 



From tlie above is obtained tlieGutta Lechak, Gutta Susu 

 or Gutta Tapak of commerce, bought in Labuan at from 

 $20 to $30 per pieul. 



5. Serapit Larat. 



6. „ Pulau. 



The produce of the Serapit is only used to increase the 

 weight of that of the Manungans, the milk not hardening 

 sufficiently of itself. 



7. Bertabu or Petabo Pulau. 



8. Bertabu or Petabo Laut. 



This gutta is no longer marketable ; it is used as a remedy 

 for ulcers — " Sakit Puru." 



If this account is correct we should perhaps talk of the 

 Manungans of Borneo, and not of the Serapits as Mr. Bur- 

 bidge proposes. 



The flowers of all three, viz., Manungans, Serapits and 

 Bertabus or Petabos are axillary and not in terminal pani- 

 cles or cymes, as is the case with the flowers of Urceola. 

 The fruits of all are edible, and the plants are distinguished 

 chiefly by the different shape of the leaves and fruit, and 

 the corrugations of the bark. 



The fruit of the Manungan Pul, or proper, is pear- 

 shaped. As the Natives say it " has a neck to it." That of the 

 Manungan Bujok is more egg-shaped — " without the neck," 

 and that of the Manungan Manga is round. The leaves 

 of the Berfcabus or Petabos are the broadest and largest ; 

 then come those of the Serapits, somewhat longer in pro- 

 portion ; and lastly those of the Menungans, which are the 

 smallest, and, in proportion to their breadth, the longest, 



Gutta and rubber are at present imported into Labuan 

 from the following rivers, viz., Barram, Meri, Bakong, Baleit, 

 Tutong, Limbang, Trusan, Lawas and Kimanis.
