FLORA OF THE SUNDRIBUNS.

extend into these newly opened settlements from the Bengal plain, 
for with only two exceptions these species are all common weeds 
in the rice-fields or the village shrubberies of Bengal. The exceptions 
are Senebiera pinnatifida and Xanthium spinosum^ both plentiful 
weeds near the banks of the Matla river which do not occur anywhere 
in the Bengal plain outside the Sundribuns, and both obviously recent 
introductions to India. It is worth noting, moreover, that among 
the first species to appear in the newest and smallest settlements 
are Ageratum conyzoides and Scop aria dulciSy neither of -which is 
originally a native of India. 
Turning now to the Sundribun species that occupy parts which 
probably have never been subjected to clearing, the first to be consi- 
dered are those that occur along the sea-face where the line of low 
sand hills to be met with at various parts of the coast afford condi- 
tions very different from those that prevail on the muddy river-banks 
or in the swampy islands, and provide a foothold for a number of 
species characteristic of the littoral of South-Eastern Asia generally. 
The following list includes all that have hitherto been reported ; in 
all cases where the species occurs elsewhere in the Sundribuns this 
fact is noted : — 
Naravelia seylanica : also northern edge of forests. 
Capparis sepiaria : also among ruins at Jatta. 
Tamarix gallica: also river-banks throughout the forests and 
especially in the northern clearings. 
Hibiscus tiliaceus : also general. 
Thcspesia populnea : planted in the northern clearings ; not 
found in Sundri-forests. 
Vitis trifolia : also general. 
A llophylus Cobbe var. glabra. 
Odina Wodter : planted in northern clearings, also on sites of 
old settlements and camping-grounds. 
Crotalaria retusa. 
Crotalaria verrucosa : also northern clearings and old sites. 
Crotalaria Saltiana : also northern clearings. 
Desmodium umbellatum : general, but rare. 
Erythrina indica. 
Canavalia lineata. 
Vigna luteola : also river-banks generally, 
Dalbergia torta : also general. 
Derris scandens\ 
Derr is sinuata.
