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. Clarkeanmn , 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. Burck’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 
VRlESE 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. st ell at urn , 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 .
