INTRODUCTORY. XXV 
Higher on the ridges, above 2,000 feet elevation, a small crooked 
_ (Hi — albicans) appears in force, associating with similarly 
ed low trees of yindyke (Dalbergia cultrata), bwé-cheng (Bau- 
fate variegata) , didoo (Bombax insigne), ta-sha-ben (Embltca offi- 
cinalis), zeng-byoon (Dillenia pentagyna), and others, and these form 
the upPER DRY FoREST. Here also some temperate forms appear for 
the first, such as an epiphytic beautiful Vaccinium (V. verticillatum), 
a large Heracleum, Hymenopogon (an epiphyte), and a few others 
Vv : orests are no doubt the most im- 
portant ones to the forester in Santas and occupy at least two-thirds 
of the whole area of Pegu oe. Chittagong, and Arracan, while 
they are less developed in Marta enasserim, and the Andamans. 
I have adopted (with slight slimeatiens the varieties of these forests 
as distinguished by Dr. Brandis in his report on the Attaran forests 
in 1860. These are now generally understood by foresters in Burma. 
are, as a whole, well demarcated in all the tracts west of the 
river, on the metamorphic strata, they become much masked by 
the surrounding forests. This is no doubt partially owing to the — 
substratum, which is here so favourable to most kinds of trees, 
while alluvium and the soft sandstone excludes so many kinds that 
are common enough on metamorphic substrata. Onthe Andamans 
they are also less demarcated, although here growing on the same 
sandstone as that of Pegu, but here the lower latitude and more 
especially the insular dant has a share in this modification.
