Vernac. Gengwa ; Geria ; Gheria ; Geo. 
A tree, 30-50 feet high ; wood white, soft, chiefly used as fuel, but also for 
making jhools, dabbas, posts, planks, native drums and toys : charcoal also is 
made from it and an oil is extracted. The juices of this tree, which is the com- 
monest of all the Suridribun species, are poisonous. 
Distrib. — Coasts of S.~E. Asia; N. Australia; and Polynesia. 
The breathing organs developed in connection with the roots of Gengwa do net 
assume the form of vertical blind root-suckers like those of Amoora, Avicennia^ 
Sonneratiaj etc., but consist of horizontal thickened segments, richly furnished 
with lenticels, that protrude through the mud, exactly as in Carapa obovata.

possibly its presence in our area is due to this fact.
