where heavy and long continued, commencing in May or the 

 beginning of June, and lasting till November, and amounting 

 at Tavoy to 208 inches, and at Maulmain to 175. In the more 

 northern parts the winter is dry, the north-east wind being 

 deprived of its moisture by high ranges of mountains. South

carpi are very common ; and a pine, probably P. Sinensis, 

 grows on the mountains north of Martaban. Calami, Zalacca, 

 and other tropical palms, are abundant in humid jungles, and 

 enormous bamboos in more open places. Teak is common 

 in the interior, but has its southern limit in 15° N. lat., 

 where the winters become too humid for its growth. The 

 Amherstia nobilis, one of the most remarkable and local trees 

 in the province, has hitherto been found only on the banks of 

 the Salueen river ; Barclay a longifolia, a remarkable genus of 

 water-lilies, is confined to this province and the adjacent one 

 of Pegu i and the Melanorrhma usitatissima, or black varnish 



tree, abounds in many parts.
