 This is E. orientate, Jacqu. ic rar. i. t. 48.— It was introduced 

 in 1813 from the Mauritius into the Hon. Company's botanic gar- 

 den at Calcutta, where it blossomed for the first time in April 1820, 

 and has continued ever since doing so in the hot season. The leaves 

 vary much according to the age and station of the tree,and even the age 

 of the branch, from linear, acuminate, to broad-oval, or sub-obovate, 

 obtuse, which latter form they have on young luxuriant shoots, and 

 then they are very lucid and marked with gland -cuspidate small 

 serratures. The inflorescence nearly like that of the first species.
