Citrus ×deliciosa (thorny (Australia), amarillo, beladi, Willowleaf Mandarin, Mediterranean Mandarin) is a citrus hybrid (mandarin × pumelo), though it was once thought to be a pure mandarin. It is related to the ponkan. It has been widely grown around the Mediterranean since it appeared in Italy (between 1810 and 1818), but was not found in the orient until it was exported there. It is one of the most commercially important citrus. Its sweet fruit is eaten, its rind oil is used to flavour food and drinks, and petitgrain oil is extracted from the pruned leaves.
