of the fruit. A large variety with thick rind furnish- 
es, candied, the Citrionate or Succade. The Cedra oil 
comes from a particular variety. 
Citrus Limonium, Risso.—The real Lemon. From 
the fruit of this is largely pressed the lemon-juice, 
while the thin, smooth, aromatic peel serves for the 
production of volatile oil or for condiments. The juice 
of this fruit is particularly rich in citric acid. <A large 
variety is the Rosaline lemon. 
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. 
Citrus Limetta, Risso.—The real Lime. The best 
lime-juice is obtained from this variety, of which the 
Perette constitute a form. 
Citrus Australasica, F. von Mueller.—Coast forests 
of extra-tropic East Australia. A shrubby species 
with oblong or almost cylindrical fruits of lemon-like 
taste, measuring 2 to 4 inches in length. They are 
thus very much larger than those of Atalantia glauca 
of the coast and the desert-interior of tropic Australia, 
which are also of similar taste. These plants are en- 
tered together with the following on this list, merely 
to draw attention to them, as likely capable of im- 
provement of their fruit through culture. 
Citrus Planchoni, F. von Mueller. (C. Australis, 
Planchon, partly. )—Forests near the coast of sub-tropic 
East Australia. A noble tree, fully 40 feet high, with 
globular fruits about the size of a walnut, called Na- 
tive oranges. The species has first appeared under 
the above name in the «Report on the Vegetable 
Products of the Intercolonial Exhibition of 1867.’’
