TH ALA MI FLORA;. 
A shrubby tree, 8-10 feet in height : brandies long, virgate, 
subtrigonal towards their extremities, glabrous, armed with 
horizontally spreading thorns. Leaves about 6 inches long and 
2 broad, serrulato-erenated, of a yellow-green colour : petiole ^ 
of an inch in length. Peduncles axillary, solitary, usually 1- 
flowered. Petals 5, oblong, obtuse. Stamens of unequal length. 
Fruit of a bright yellow colour : rind divisible into two layers ; 
that which is external, composed of an infinite number of vesi- 
cles filled with essential oil ; the other, which is internal, thick, 
white, and forming the principal bulk of the fruit : pulp enclosed 
in a diaphanous membrane, and arranged into several compart- 
ments : compartments many-seeded. 
The Citron is originally a native of Media. It passed from 
thence into Persia, and in course of time became known to the 
Greeks. It is considered to be the Malus Medic a of Theo- 
phrastus, and the Malum Medi.e of Virgil. From a very 
early period, the Jews were acquainted with it. It is the fruit 
Hadar, — “the fruit of the tree that is beautiful” — mentioned 
in Leviticus (ch. xxiii. v. 40), which the people were directed 
on the Feast of Tabernacles, to bring with the young unde- 
veloped leaves of the date palm before the Lord. This injunc- 
tion is strictly observed to the present day. Particular care is 
taken to distinguish the proper fruit by its mammillated or tu- 
berculated appearance, as the Lemon frequently acquires the same 
shape and size. Should the style or stigma be defective or in- 
jured, the fruit is immediately rejected. We find, in old Sama- 
ritan coins, a Citron represented attached to a palm : and Jose- 
phus informs us, that on one occasion, when Alexander, the 
King and High Priest, stood at the altar, the people revolted, 
and threw at him the Citrons they held in their hands. 
This fruit is used only in confections. The pulp is in small 
quantity, and contains little acid. The rind affords a consider- 
able proportion of essential oil.
