P. Maingayi, King and Gamble, is the Getah Taban Simpor, and 

 I have it also under the name of Jelutong Batu, though of course, 

 it has nothing to do with the real Jelutong. The leaves are in shape 

 somewhat like P. obovatum, but instead of being grey beneath are 

 covered with golden hair. The tree attains a height of 60 to 80 feet 

 with a diameter of 3 to 4 feet. It occurs in Perak, Malacca and 

 Jelebu. 



P. Clarkeanum, King and Gamble, is closely allied to if not merely 

 a variety of the last species but it is rather hairier. Mr. Arden 

 who sent specimens from Selangor says that the Malays called it 

 Getah Ketapang (doubtless from its resemblance to the Ketapang 

 tree, Terminalia Catappa^) and find its latex useful for adulterating 

 gutta percha. 



P. oxleyanum, Pierre (Dichopsis pustulata> Hemsley), is known to 

 the Malays of Perak as Taban Sutra, or Taban putih, and Mr. 

 BURN-MURDOCH sends leaves from Kuala Lumpur of what is 

 doubtless this plant, saying that the Malays there also calls it Getah 

 putih and use it to mix with Getah Jelutong. WRAY also gives Getah 

 Taban chaier (lit watery Gutta percha) as a name for it. Burek's 

 P. oxleyanum ) collected by TEYSMANN in Banda is a totally different 

 plant. 



P. xanthochymum, Pierre (Dichopsis rubens Clarke). A big tree 

 with leaves which turn bright red when they dry, is said by De 

 VRIESE to give a yellowish gutta percha of second quality. The 

 plant does not appear to be common though it grows in Singapore, 

 Malacca and Perak. I have not heard of its gutta being utilized at 

 all here. 



P. bancanum, Burck. A gigantic tree of which there is a splendid 

 example in the Botanic Gardens is said by KING and Gamble to 

 give a kind of gutta percha. It certainly does contain a small quan- 

 tity, but it appears to be very scanty. Mr. BURN-MURDOCH sends 

 a few leaves of a plant known as Niato which appear to belong to 

 this species. 



P. Ridleyi, King and Gamble, Niato Hitam or Maiang is a big 

 tree, 50 to 60 feet or more tall. The timber is said to be very 

 flexible and durable but difficult to saw. It is heavy and is used in 

 house building. 



P. Herveyi, King and Gamble, the "Jungak" is a tree 40 to 50 

 feet tall, has an inferior light wood, not durable if exposed, and 

 according to Wray the gutta is sticky and worthless. It does not 

 seem to be a very common tree. 



P. stellatum, King and Gamble, only known from one collecting 

 by Scortechini in Perak is said by him to give good gutta but in 

 small quantities. 



Daru. — The timber known as Daru is not yet identified. Accord- 

 ing to Mr. CANTLEY quoted by Messrs. KING and GAMBLE it is 

 produced by Sideroxylon.
