Citrus × sinensis

Citrus × sinensis, also known as the Citrus aurantium (Sweet Orange Group), includes the commonly cultivated sweet oranges, including blood oranges and navel oranges. The orange fruit is an important agricultural product, used for both the juicy fruit pulp and the aromatic peel (rind). Orange blossoms (the flowers) are used in several different ways, as are the leaves and wood of the tree. Giant swallowtail caterpillars (Papilio cresphontes) cause serious damage to this crop, especially to young trees.
