68 THE GYMNOSPERMS OF THE MALAY PENINSULA. 
Native Name “ Pakis Laut” on account of the circinate 
vernation of the young leaves. A starch is obtained from the 
trunk, and the young leaves are eaten as a potherb. Usually 
this inhabits sandy spots near the sea, or on the sea beach, 
but I have met with it far inland in forests, e.g. at _Kamuning. 
It is probable that in these cases, the plant has remained here 
since the formation of the alluvial flats now between it and 
the sea. 
It was probably much more abundant on our sandy coasts 
but has disappeared except where isolated in gardens, owing to 
these spots being cleared and cultivated for coconuts. 
The male cone has a strong odour of lady-birds, the pollen 
which is very abundant is said to be strongly narcotic.
