AURANTIACEa:. 



319. C. Limonum Bisso ann. mus. xx. 201. DC. prodr. 

 i. 539. — (The Lemon.) 



Leaves ovate-oblong, usually serrulated, pale green, with a winged 

 stalk. Flowers middle-sized, purple externally. Fruit oblong, very 

 uneven, now and then almost round, with a pale yellow rind. Cysts in 

 the rind concave. Pulp juicy, very acid. — Juice of the fruit yields 

 citric acid ; when properly diluted and slightly sweetened it is a most 

 agreeable and refreshing beverage. The essential oil of the rind is 

 recommended by Mr. Foote as a stimulant in various inflammations of 

 the eye. Med. hot. trans. 1834. p. 79. The peel itself is aromatic and 

 stomachic ; but it does not agree with all stomachs.
