Of the 368 species, 232, making 65 per cent, of the whole, occur at 
once in Indo-China, Malaya and the Andamans; 40 occur in Malaya and 
the Andamans, 8 of these extending to Tenasserim but not occurring in 
Burma or Siam (Indo-China proper) ; 22 occur in Indo-Ohina but not in 
Malaya, 12 of them being present in the Andamans also; 40 occur in 
the Andamans without appearing either in Indo-China or in Malaya, 
though 8 of these appear in Tenasserim, which connects Indo-China with 
the Malay Peninsula, just as the Andamans connect Indo-China with the 
Malay Archipelago ; 8 occur only in the Coco Islands and Tenasserim, 
and 13 are apparently confined to the Coco group. This last number is 
probably too high ; some of these species, as well as some of those others 
for which the Coco locality is as yet the only record from the Andamans, 
may occur in North Andaman. 
The following table gives the distribution of the species in these 
three districts as well as in the sub-district of Tenasserim : —

This table therefore leads to the conclusion that phy togeographically 
tall, but extremely hard and tough, and forming dense thickets very difficult to pass 
through—a general description agreeing very well with that of Dendrocalamus strictus 
as it occurs in Great Coco.
