The affinities of these plants may be said to be with 

 Javanese species except Cryptocarya and Pandanus 

 Nativitatis, which are allied to Australian and New 

 Caledonian species. 



As Oliver (Journ. Linn. Soc. 1. c. 352) remarks " most 

 of the plants could not be exactly matched with their 

 congeners from Java but yet do not sufficiently differ to 

 be specifically distinguished, an indication of consider- 

 able age of the flora," and indeed this is so, for besides 

 these distinguished as distinct species several others are 

 very unlike the plants as we know them from surround- 

 ing countries, eg., Randia densi/lora, Callicarpa longi- 

 folia, Ochrosia Ackeringae and Leea sambucina. Still it 

 must be taken into consideration that the locality where 

 these plants grow is very unlike their habitats in Java 

 and the Malay Peninsula. The soil is very rich in 

 phosphates and lime, and extremely porous, so that in 

 the dry season it becomes extremely dry, the water soak-
