This plant differs from the other Sonneratie in being

and perhaps in the structure of the seed. 
Both it and Sonneratia vere have a peculiar aapéct de- 
pendent upon the stomata being present on both sides of the 
leaves, but in Duabanga, they are confined to the lower side. 
On what account the genus was placed among Myrtacez 
is difficult to conceive, that order being extremely well de- 
fined, and presenting no approach to such a structure of the 
calyx, and freedom of ovary. 
If Sonneratia belongs to any order titheHo: characterised,

there. In this case the section will come near Lagerstroemia.
