said to be over 600 years old; and another at Hampton Court, 

 grown under glass, over 200 years old. Spain and Sicily also 

 have trees of great age. At Versailles there is a seedling 

 planted in 1421. At Nice there is a tree 50 feet high, with, a 

 trunk over 3 feet in diameter, which is said to produce 6,000 to 

 7,000 oranges in a year. 



The flowers are white, the leaves lanceolate or oblong. The 

 petiole is not so markedly winged as in the bitter-sour orange, 

 but is always present to a greater or less degree. The fruit is 



generally an oblate 

 sphere, pyriform or 

 elliptical, of a gold- 

 en color when ripe, 

 and full of delicate 

 pulp and sweet, 

 refreshing juice.
