Vernac. Bilati Jau, 
A tall handsome tree ; wood brown, very hard and durable, but apt to crack ; 
makes excellent fuel. 
Distrib. — Shores of Indo-China ; Malaya; Australia; Polynesia. 
The presence of this species within our area as a wild tree, far from an}^ 
planted examples, was first noticed by Mr. Lace. Probably the seeds which have 
given origin to these trees along the Jeodhara Khal, have been brought down by 
the stream from Morellganj, where, an avenue of Casuarinas exists that was 
planted about 100 years ago.
