moist-deciduous forests, containing teak and other species, with con¬ 
tinuous bamboo forests up to the top of the western watershed, which 
constitutes the boundary of the Pegu Division. This type of heavy 
teak and bamboo forest with small modifications, occurs all over the hill 
ranges, passing northwards through the Okkan Reserves into the 
Tharrawaddy Division. 
(3) Area of forests covered with bamboos. 
The above-mentioned Plains Forests, which constitute the North 
and South Hlaing Reserves, have been eliminated from this scheme, 
as they contain relatively few bamboos. The areas taken into consider¬ 
ation are those which comprise the forests situated on the hilly ground 
in front of the main ridge of the Yomas and which go to make up the 
western watershed of the main range. For the sake of convenience, the 
area has been divided into two parts, according to the lines of export 
available, though both reserves form one continuous block of forest:—

(4) Species of bamboo and mode of growth. 
The prevailing species are Cephalostachyum pergracile (Tinwa) and 
Bambusa polymorpha (Kyathaung) which together make up about 80 per 
cent, of the bamboo growth. Dendrocalamus >,trictus (Myin) occurs on 
the ridges, and is often found growing on poor soil, but, for reasons stated 
elsewhere, this species has not been included in the scheme. Besides the 
above bamboos, a creeping species occurs, known as Teinostachyum Helferi 
(Wathabut) and a bamboo named Dendrocalamus longispathus (Waya). 
The two first-named species, Tinwa and Kyathaung, are very 
abundant. The former is a comparatively small unarmed bamboo, with 
an average stem of 6" to 7" mid-girth and cutting into lengths of 25 to 
30 feet. It yields a fairly strong stem, but not thick-walled, and is 
easily cut and extracted. The latter is a larger unarmed bamboo, with
