riose are enlarged into as many oblong, lanceolate wings many 

 times longer than the capsule itself; the other two continue 

 of their original length, but so contracted in breadth as to be 

 filiform. Seed solitary, affixed to the base of the capsule. Pe- 

 risperm and embryo as in the Convolvulacea, to which order 

 it belongs. 



Obs. A large plant, from thirty to forty feet long, covering 

 a mango tree, is now in full blossom before me, and is certain- 

 ly a most lovely sight ; the long pendulous extremities of the 

 branches, with their numerous panicles of small, white flow- 

 ers, and hoary leaves, render it a very pleasing object.
