Diiknia.] FLORA INDICA. 69 



Hab. In Zeylnnia, Thunherg. 



Arbnr. Folia integerrima vel a medio ad apieem obscure eernilata, subspitha- 

 mrea, palmam lata. Peiioli vUlosi, poUicares, canaliculati. Sepala oblonga. Pe- 

 tala obovata, li-pollioaria (ex icone Thunberg.). 



We have not seen auytbing like this from Ceylon ; in general character it ap- 

 proaches very closely to W. oblonga. Wall., but that belongs to the first section.

The species of this genus are all Indian, and inhabit the dense tropical forests 

 among the mountains. One species skirts the base of the Himalaya to 28° N. lat. 

 Most of them flower before the expansion of the leaves, which are generally of great 

 size, and vary a good deal in shape. On this account the species are very difficult of 

 discrimination, and it is possible that we may have reduced their number too much. 

 AVe believe, however, that it is much more advantageous to science to limit our lists 

 to the species which are well known tliau to establish new species on insuiBcient 

 grounds ; and we must leave to botanists ia India who may have an opportunity of 

 observing these trees in their native forests or in cultivation, the task of ascertaining 

 the degree of variation to which they are subject, especially in size and shape of 

 leaves, and in the length of the petiole.
