Kumquat
Kumquats, sometimes spelled cumquat, are a group of small, angiosperm, fruit-bearing trees in the family Rutaceae. The edible fruit closely resembles the orange 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.
