Orange Sculpture

Nevertheless, names have been given to the various members of the genus. The name "orange" applies primarily to the sweet orange, Citrus sinensis, which accounts for about 70% of world citrus production.
Other citrus species known as oranges include:
• The bitter orange, Citrus aurantium, also known as Seville orange, sour orange (especially when used as rootstock for a sweet orange tree), bigarade orange, and marmalade orange.
• The bergamot orange, Citrus bergamia Risso, which is grown primarily in Italy and used primarily for the peel, which flavours Earl Grey tea.
