Halophobous perennial of sunny or slightly shadowed, 

 humid or marshy soils, spread throughout Java from the plains 

 to an altitude of 1600 m., often occurring on water-sides. 

 The fruits remain enclosed within the (after the anthesis) 

 somewhat enlarged perianth, hence possess floating power. 



A few specimens on the base of the wall formed by the 

 rupture. 



Olacaceae. 



21. Ximenia amcricana L. 



Spinous shrub, found in Java in many places but exclusively 

 on the beach. The reproduction is effected by the fruits '') 

 which possess floating power because of the testa being 

 thick and corky. 



One specimen on the beach.

24. Albizzia retusa Bth. 



Small tree, found in Java here and there on sandy beaches 

 rich of lime. The pods which possess a rather thick corky 

 rind do not burst when ripe but easily break into fragments 

 each of which contains one or more seeds- These fragments 

 possess floating power. 



One young specimen on the beach. 



25. Sophora tomentosa L. See p. 147, No. 21. 



One specimen somewhat behind the floodmark.
