60 BOTANV. 



Pterocarpus Wallichii ; but did not suspect that the ex- 

 udation of the tree was good gum kino ; and Dr. Grif- 

 fith collected specimens of Garcinia elliptica with his own 

 hand in the province of Mergui ; and yet remained ignor- 

 ant that the tree produced gamboge, which cannot be 

 distinguished from the best gamboge of commerce. 



When more attention has been paid to the geographical 

 distribution of plants, the Tenasserim flora will probably 

 show, that the climate of the plains on this Coast corres- 

 ponds to one on the hills several thousand feet high on 

 the other Coast. 



Roxburgh says that a species of oak, Quer cits fenestra, 

 is a native of the mountain! in the vicinity of Silhet ; on 

 this Coast the same species grows indigenous not fifty feet 

 above the level of the sea. A gamboge tree, Garcinia 

 yictoria, grows, he says, " on the highest parts of Wyn- 

 aad," but the same tree grows at the foot of the hills in 

 Tavoy, which border on tide waters. A species of willow, 

 he describes as " a native of banks of rivulets and moist 

 places among the Circar mountains," but we have a spe- 

 cies of willow on this Coast which is met on every stream 

 before the influences of the tide ceases to be felt. The 

 chestnut, Castanea indie a, he writes, " is a native of the 

 hilly frontier of Bengal ; " but the chestnut of this coun- 

 try, Castanea martabanica, grows nearly down to the sea 

 shore. Speaking of the wood-oil trees, Dr. Wight re- 

 marks : " In this neighbourhood, Madras, several species 

 are found, but all natives of hilly tracts forming the Bala* 

 ghaut. In Pegu, where they abound, they occupy the 

 plains." He refers all the species of Vatica to the 

 mountains, but we have one that drops its curious winged 

 frait from cliffs that overhang the sea. 



Ardcsia humilis is a common shrub at Tavoy growing 

 down to the plains ; but its habitat on the other coast is 

 "the eastern slopes of the Neilghef ies in subalpine jungle." 



IVrightca Wallichii, Wight states, is found on " the 

 slope of the Neilgheries from about the middle of the 

 ascent to the elevation of between 4000 and 5000 feet ;" 

 but "the original specimens of this species were collected 

 in the Tenasserim Provinces."
