Nypa palm (Nypa fruticans Wurmb.) is a kind of palm growing very well in the brackish water forest or along the river near its mouth.  In some countries, it is considered to be invasive plant, so that its development shound be controlled.  The aim of this study is to find out the morphological distribution of the nypa along Cilacap and Kebumen coastal areas of Central Java.  The method used in this study is survey.  The sampling was taken by stratifying the river based on distance from the sea namely: 0-<50 m, 50-<100 m, 150-<200 m, 200-<250 m, >250 m from the sea water.  The other enviromental factors meassured included water salinity, water pH, soil pH, and soil type.  The nypa characteristics meassured included leaf morphology and size, and plant individual density.  The results of this study based on the distance from the coastline showed that: 1) The nypa is mainly distributed a long the river with Grey regosol and Aluvial Hydromorph soils; 2) erect leafed nypa are present close to the water while the curved leafed nypa were presence in the inner part of the areas;  3) Based on the midrib color, the young, medium, and old nypa leaves tend to have green, greenish yellow, and orange midrib respectively. 4) Based on survivability, the nypa seeds tend survive in water further inland.
