612 poLYANDRiA MONOGYNiA. Dipteroccirpus. 



will I think justify their being considered three very- 

 well defined genera, provided we admit that the Mono- 

 phylhis and polyphyUiis, calyx and corol ought to con- 

 stitute genera, even though they agree in the rest of the 

 character and habit. 



1. D. turhinatus. Gccrf. Sem. 3. t. 188. 



Spikes axillary, drooping. Leaves ovate-oblong, glossy 

 and ribbed. Body of the calyx without wings, or angles. 

 Anthers thirty, bristle-pointed. 



Beng. Tileeya-gurjun about Tipperah and Chittagong 



A native of Chittagong, Tipperah, Pegue, &c. to the 

 eastward of Bengal, where it grows to be an immense tree. 

 Flowering time the beginning of the hot season ; the seed 

 ripens in June. 



Trunk straight throughout, to the very top of the tree, 

 and growing to an immense size, even so large as to be 

 made into canoes that will carry an hundred men. Bark 

 deeply cracked. Branches, the inferior ones spreading, 

 the superior ones ascending. Branchlets bifarious. Young 

 shoots hoary, and marked with scars of the fallen stipules. 

 Leaves alternate, short-petalled, bifarious, ovate-oblong, 

 some entire, some waved, and some are even serrate or 

 dentate, smooth on both sides, of a deep shining, glossy 

 green. Veins many, straight, simple and parallel, nearly 

 as in Dillenia indica ; from four to twelve inches long. 

 Stipules within the leaves, very large, sword-shaped, 

 downy, caducous. Spikes axillary, drooping, solitary, 

 shorter than the leaves, smooth. Flowers solitary, remote, 

 alternate, large, white, with a very slight tinge of red. 

 Calyx one-leaved ; tube rather gibbous. Border five-part- 

 ed, irregular; two of the divisions being much larger than 

 the other three, and continuing to increase till the seed is 

 ripe. Petals five, narrow, obliquely wedge-shaped, smooth 

 on both sides, and entire, except that sometimes they 

 are emarginate. Filaments about thirty, short, inserted
