n.
Any of several evergreen shrubs or small trees of the genus Fortunella ( rue , or citrus, family), or their fruit.
Native to eastern Asia, kumquats are cultivated throughout the subtropics. The mainly thornless branches bear dark green, glossy leaves and white, orangelike flowers. The small, bright orange-yellow, round or oval fruit has mildly acid, juicy pulp and a sweet, edible, pulpy skin. Kumquats may be eaten fresh, preserved, or candied, or made into jams and jellies. In the U.S., hybrids have been produced with other citrus fruits.
