This tree was introduced from Chittagong by the late Mr. John Roxburgh in 1807. It is deciduous, and of very 

 slow growth. At the time of flowering it is entirely destitute of leaves, instead of which it is covered by countless 

 numbers of elegant and fragrant yellow blossoms, which last, however, only a few weeks, and are soon succeeded by 

 a plentiful crop of small, round, orange-coloured fruits. The fleshy leaves of the calyx, which co^ er these, have a 

 pleasantly acid taste, and are used in curries by the inhabitants of Chittagong, (of which district of Bengal the tree is 

 a native,) in the same manner as those of Dillenia speciosa {Chalta of the Bengalese). The tree is in full foliage 

 during the rainy season. 



It differs from DiUenia aurea Smith, in having smaller, simply serrated, villous, and soft leaves, and small flowers, 

 disposed in round lateral fascicles on the naked branches. From the figure of that species in Exotic Botany, vol. ii. 

 t. 92 and 93, it appears that the inner series of the stamens is shorter than the outer 5 in our species the reverse is 

 the case. From Dillenia jjentagyna, Roxb. {Colhertia coromandeliana, Decand.), it differs in having larger flowers, 

 bracted peduncles, and 6 or 7 pistils with acute stigmas. Its leaves are not one half the size of those of the last- 

 mentioned species. 



The structure of the seed is somewhat peculiar. The base of it is divided into two unequal, tooth-formed lobes, 

 separated from each other by a narrow sinus, into which the fleshy axis of the fruit insinuates itself. One of these 

 lobes, namely the inferior, is larger than the other, and forms in fact the base of the seed, being hollow within for 

 the reception of part of the perisperm and the embryo. The other, or superior lobe, is smaller and solid, being 

 formed by a simple elongation of the testa. It sometimes happens, that the interstice, or sinus, is subdivided by a 

 transversal partition, which gives the seed the appearance of being two-celled, one of the cells being embryoniferous, 

 the other vacant.

This noble tree is rather common in the forests of the principal rivers in Martaban, where I know from experience 

 that it has not unfrequently been mistaken for the Teak (also a native of that province), to which, indeed, it has some 

 resemblance when in full foliage. Tlie flowers are large and fragrant, and produced in vast abundance.
