Lemon 
The lemon is the fruit of the tropical 
or sub-tropical tree Citrus Limonum or 
Citrus medica, variety Limonum, of the 
orange family. The fruit is ellipsoidal 
with a protruding point at each end, the 
color is bright yellow, the rind is thick 
and the pulp and juice very acid. 
The wild stock of the lemon tree seems 
to have been brought from the valleys of 
Kumaon and Sikkim in the northwest 
provinces of India. It was probably un- 
known to the Greeks and Romans in their 
days of power, and is supposed to have 
been introduced by the Arabs into Spain 
between the 12th and 18th centuries. 
As a cultivated plant the lemon is now 
grown in almost all the tropical and sub- 
tropical countries of the world. In the 
United States it is chiefly grown in Flori- 
da and California, but it is grown to a 
ENCYCLOPEDIA OF PRACTICAL HORTICULTURE 
limited extent in all of the Gulf states 
and in some of the southwestern states. 
Like the apple and the pear, the lemon 
varies considerably under cultivation. 
Varieties 
“Risso and Poiteau enumerate 47 va- 
rieties of this fruit, although they main- 
tain as distinct the sweet lime, with 
eight varieties, and the sweet lemon, with 
12 varieties. 
“The lemon is more delicate than the 
orange, although it grows under practi- 
cally the same conditions and requires 
Similar treatment.”—Encyclopedia Brit- 
annica, 
The lemon tree is exceedingly fruitful 
and ripens its fruits during every month 
of the year, but the principal crop is har- 
vested about the end of the year. The 
fruit is picked while green and packed in 
boxes preparatory to shipping, each lem- 
on being wrapped in paper in much the 
same manner as oranges, or “Western 
boxed apples.” 
The culls, consisting of unsound, un- 
ripe or malformed fruit, are used for the 
manufacture of essential oils and juice. 
Lemon juice is often used for medicinal 
purposes, as a tonic to counteract ma- 
laria, or as a cure for scurvy and other 
diseases. A concentrated lemon juice gen- 
erally known as citric acid is much used 
by physicians. Also the oil of lemons, 
which is obtained by pressing the rind, 
is used in medicines. 
Since the lemon is so nearly in its hab- 
its like the orange we refer the reader to 
the article on orange for a fuller discus- 
sion of the subject. See Orange.
