Ulmaceae. 



17. Trema orientate Bl. (Inclusive of TV. amboinense Bl. under 



which name this species is mentioned in Ernst's paper). 

 See p. 132, No. 15. 



Several specimens, among which some rather large ones, 

 on the older parts of the beach. 



Moraceae. 



18. Ficus fulva Rcinw. See p. 133, No. 17. 



Several young specimens on the older parts of the littoral 

 plain. 



Lauraceae. 



19. Cassytlia filiformis L. See p. 91, No. 7. 



Many specimens, especially on the older parts of the 

 beach, parasitizing on diverse plants. 



Leguminosae. 



20. Pithecolobium umbellatum Bth 



Small spinous tree, spread from West- to East-Java but 

 almost exclusively on heavy soils near the sea, often on 

 the inner border of the mangrove, less frequently on sandy 

 or rocky coasts, exceptionally in the interior. The reproduc- 

 tion is effected exclusively by the articulate indehiscent pods 

 which, when ripe, easily break into fragments. These frag- 

 ments possess floating power because of their rind being 

 thick and light; the seeds sink in water. 



One specimen on the older firmer part of the littoral plain. 



2/. Sophora tomentosa L. 



Erect shrub, restricted to beaches rich of lime and defi- 

 cient in humus. It is spread from West- to East-Java and 

 chiefly occurs on coral coasts but also on coasts that are 

 rich of shells. The reproduction is effected exclusively by 

 seeds; the pods, which after having reached full maturity 

 remain attached to the plant for yet a long time, do not 

 burst, but their rind slowly decays till at last the seeds fall 

 out. These seeds possess floating power in consequence of 

 the cotyledons consisting of a spongy tissue 1 ). 



A few specimens on the younger parts of the beach 

 somewhat behind the flood-mark.
