Vatica cinerca, King. Lankawi common, Kwah, (Curtis, etc.) 

 Endemic. 



Y. lankaiciensis, Ridl. Lankawi (Curtis Gunong Raya (Aniff). 

 Endemic. 



Pachyjiocarpus Wallichii, King. Trang (Kunstler). 



Distrib. whole Peninsula and Banka. 



Pachynocarpus umboiiatus, Hook. fil. A tree 30 to 40 feet tall. 

 Lankawi at Sungei Batu Asap (At iff). This plant origi- 

 nally described from Borneo and Labuan has been 

 collected by Curtis at Batu Feringhi in Penang, but 

 apperently overlooked in the Materials. Curtis in his 

 field notes calls it P. Wallichii, var A, distinguishing 

 it from the true plant, his var B by its having yellow 

 (not white), petals and larger coarsely veined leaves. 

 The Lankawi plant has large leaves like those of Vatica 

 Bidleyana, Brandis which I think should be a Pachyno- 

 carpus too. The stems have been attacked with galls 

 half an inch through which are densely covered with 

 bright fox-red hairs. The seed is smooth round and 

 oily. Curtis gives the name Resak for it, a name 

 applied to several timbers of this group. The Lankawi 

 specimens are in fruit. 



Balanocarpus anomalus. King. Lankawi (Curtis 1684). 

 Endemic.

 Batu Asap and Gunong Rayah at 1,500 feet elevation

Common on sandy places usually near the sea in 

 Burmah. The whole Malay Peninsula, Sumatra and 

 Bangka. It is not usual to meet with it high up inland 

 as on Gunong Raya.
