irrespective of the ordinary culinary use of the fruit. A large 

 variety with thick rind furnishes candied the citrionade or 

 succade. The Cedra-oil comes from a particular variety. 

 France produced in 1890 over 50,000 cwts. candied Orange and 

 Lemon Peel, valued at 60,000 (Sahut, from Bull, du Miuistere 

 de 1' Agriculture) ; 173,680 cwts. of Citrons were raised besides, 

 of the value of 73,000. 



Citrus Limonium, Risso. The true Lemon. Lemon-juice is 

 largely pressed from the fruit of this variety, while the thin 

 smooth aromatic peel serves for the production of volatile oil 

 or for condiments. The best oil is obtained by the so-called 

 Ecuelle process (puncturing the rind) ; distilled oil is of inferior 

 quality [Watt]. The quantity of essential oil of lemon 

 exported from Messina alone during 1887 amounted to about 

 440,000 Ibs., valued at 125,000 ; while about 500,000 gallons 

 of lemon-juice were exported during the same period. The 

 juice of this fruit is particularly rich in citric acid. A large 

 variety is the Rosaline-Lemon. A Giant-Lemon has quite 

 recently been introduced into Victoria from some mountains in 

 Fiji by Messrs. Chaffey, through Mr. R. Sawers. It shows 

 immunity against fungus-blights ; its fruit may occasionally 

 attain a weight of 4^ Ibs., and a girth of 22^ inches ; it has a 

 thick peel and delicious flavor ("Mildura-Cultivator," 4th October, 

 1890). 



Citrus Limetta, Risso. The true Lime. The best lime-juice is 

 obtained from this variety, of which the Perette c institutes a 

 form. Less hardy than most other varieties. The Lime is one 

 of the best and most enduring hedge-plants for warmer countries 

 [H. A. Wickham]. 



Citrus Lumia, Risso. The Sweet Lemon, including the Pear- 

 Lemon, with large pear-shaped fruit. Rind thick and pale ; 

 pulp not acid. This variety serves for particular condiments. 



A Tipperah-variety, known as " Sour Pomelloe," produces richly, 

 the fruits abounding in exceedingly acid juice [Bartlett]. West 

 Indian limes are particularly well produced in sub-tropic Eastern 

 Australia [J. S. Edgar]. 



Coal-oil proved the most effectual remedy in Florida to dislodge 

 scale from any parts of citrus-plants ; half a pint of oil is to be 

 mixed with sifted wood ashes, and then with 6 gallons of water, 

 this fluid to be syringed over the trees. Mr. Silberbauer recom- 

 mends a mixture of 1 ib. genuine whaleoil-soap in 5 gallons of water 

 for periodic syringing to subdue the Icerya. Capnodium citri is the 

 ordinary Black-smut of Citrus-trees. 



Citrus Planchoni, F. v. Mueller. (O. Awtralis, Planchon, partly.) 



Forests near ^the coasts of sub-tropic Eastern Australia. A noble 

 tree, fully 40 feet high, or according to C. Hartmann even 60 feet
