Kumkwat

Also known as cumquat, kumquats, cumquats

Kumquats ( ), sometimes spelled cumquat in Australian English and British English, are a group of small, angiosperm, fruit-bearing trees in the family Rutaceae. The edible fruit closely resembles the orange (Citrus x sinensis) in color, texture, and anatomy, but is much smaller, being approximately the size of a large olive. They are native to southern China but have been cultivated for centuries in Japan and Southeast Asia. The kumquat is a fairly cold-hardy citrus.
