Tbis is a very distinct and beautiful species, tbe flovi^ers of wbich are remarkable on account of tbe sweet perfume 

 which they emit, and their variegated appearance, changing from a bright yellow colour, which they have at first, 

 to a deep orange. I have only found the tree on the calcareous hills about Segaen, on the banks of the Irawaddi, 

 opposite to the city of Ava.
