51. Me/ochitj umbellata Stapt (M. indica A. Cray). 



Small, fast-growing, heliophilous, halophobous tree which 

 lays but few claims to the fertility of the soil and thrives 

 as well in constantly rather humid (but not marshy) soils as 

 in periodically very dry ones. It is spread throughout Java 

 from the plains up to an altitude of +1700 m., especially 

 beneath 1500 m. and often grows in deserted fields invaded 

 by Imperata, where it is one of the pioneers of the young 

 secondary forest that is to cover them in time Moreover 

 it is found in grass-jungles, thickets and in light forests, 

 locally often in numerous but usually scattered specimens, 

 which already from afar catch the eye by their whitish 

 crown. The reproduction is exclusively effected by the light 

 winged seeds.
