Orange Sculpture

Terminology and scope
All citrus trees are of the single genus, Citrus, and remain almost entirely interfertile; that is, there is only one "superspecies" which includes grapefruits, lemons, limes, oranges, and numerous other types and hybrids.
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.
