A—EVERGREEN FORESTS. 
The evergreen forests consist of trees which are green all 
the year round, although a few of them shed their leaves after a 
rtain number of years. In higher elevations of the Martaban 
and Tenasserim hills they beeome intermixed with winter-deciduous 
trees, but these latter are so scanty as not to affect the aspect. 
I. Lrrrorat Forrsts.—These are low-land forests growing on 
the silty alluvial lands bordering the sea. But they ascend also the 
rivers as far as the tidal waves. Salt water is the modifying 
agent of these forests, and they differ in their aspect according to 
the saltiness of their waters, as affected by the influx of fresh water 
fro e rivers or from rains. Along the sea itself, and often far 
extending into it, form MANGROVE FORESTS, consisting chiefly of 
rhizophors, such as pyoo (Rhizophora, Bruguiera, etc.), kambala 
(Sonneratia apetala), tamoo (Sonneratia acida and 8. Griffithii), 
- boo-tayat (Aegiceras corniculata), pmlay-kanazoo (Carapa obovata), 
and other smaller trees, like Kandelia Rheedei, Ceriops, Lumnitzera 
racemosa, Scyphiphora hydrophyllacea, and sometimes Brownlowia 
lanceolata. e ground is muddy in the extreme, and more or less 
destitute of vegetation. Further inland, where the grounds are 
inundated only during spring-tides, these mangrove forests pass into 
the so-called TIDAL FoRESTS, in which most of the above-named trees
