HUGHLI-HOWRAH AND THE 24-PERGUNNAHS.

adnascens and Vittaria elongata. These, however, are in no way 
distinctive of the Sundribuns ; their presence is due to the fact 
that it is only in the Sundribun part of our area that the forest 
conditions suitable for their growth are really to be found. A full 
account of the Sundribun flora will be found in Vol. II of these 
Records. 
The rest of the species included in the list belong to four distinct 
groups:— (1) Species that are common to the Gangetic delta north 
of the Sundribuns and to the Sundribuns ; (2) Species that are com- 
mon to the Gangetic delta and Western Bengal, but that do not go 
into the Sundribuns; (3) Species that are neither to be found in the 
Sundribun forests nor in Western Bengal or beyond ; and (4) a 
residuum of species that are cultivated or are manifestly introduced 
plants. 
The species of the first group include plants that have either 
been left behind as the conditions of our districts became altered 
from their former swamp forest state, or that have, under the influence 
of the tides which affect the various rivers and creeks, invaded our 
area from the Sundribuns. They, however, include a few that on the 
other hand have obviously invaded the Sundribuns from the north ; 
these in some cases at least are common to Western Bengal and to 
the deltaic area. Taking first the plants of this latter sub-group we 
find that they include Naravelia zey tunica , Cratseva religiosa,
