that disappears, an instance of the genus having been found by Dr. 

 Yoigt about Serampore, and by Lieut. Kittoe at Midnapore. This 

 genus also occurs at Mergui and Moulmein, but has not hitherto 

 been remarked on the Khassya Hills or in Assam. Another Aus- 

 tralian form, Melaleuca Leucadendron, forms from its abundance 

 in the low littoral tracts of Malacca a very marked feature of vege- 

 tation. The northerly limit of this species is Mergui, (12° N. L.), 

 where it occurs in similar localities, but comparatively limited in 

 size and numerical extent. 



Three of the four species above alluded to, may be thus distin- 

 guished : —

 ceolatis glaberrimis, calyce extus pubescente intus cum ovario dense 

 albo-tomentoso, staminum phalangis 4-6-andris.
