An orange is a delectable pulpy fruit that belongs to the genus Citrus, the other famous members of which are lemon, lime, and grapefruit. The scientific name of the sweet orange is Citrus sinensis, while the name of the bitter variety is Citrus aurantium. The orange is considered a hybrid, possibly between Citrus maxima (pomelo) and Citrus reticulata (mandarin).
The fruit is covered by a bright yellow to orange-colored skin, known as the epicarp, and a thick, spongy mesocarp that lies beneath the epicarp. The internal part is divided into several individual segments (10 or more) with thin, but tough skins, that hold together the actual juicy pulp. Inside the segments, you can also find seeds that are known as 'pips'. Oranges became famous throughout the world, when they emerged as a miraculous cure for the disease, scurvy. Let's find out some more facts about the history of this amazing fruit.
