Fortunella margarita is a small, evergreen tree that belongs to the citrus family, Rutaceae. It is commonly known as kumquat, and is native to southeastern Asia, particularly in China. The tree can grow up to a height of 3-4 meters and has dark green, glossy leaves with thorny branches.
The fruit of the Fortunella margarita tree is a small, round or oblong fruit with a diameter of about 2-5 centimeters.
