The fruits are drupes with yellow epicarp and abundant pubescence. In a citrus fruit, the epicarp and mesocarp make up the peel. The epicarp is smooth and the mesocarp is fibrous. Epicarp mature fruits splits off from endocarp, which splits ~1/4 of its length. The epicarp forms the tough outer skin of the fruit, if there is one. The epicarp is sometimes called the exocarp, or, especially in "citrus", the flavedo. The epicarp is fibrous, the mesocarp fleshy, covering a five-lobed seed, resembling the dry fruit.
