Citrus leiocarpa
Koji orange (コウジ) (Citrus leiocarpa), also known as the smooth-fruited orange, is a Citrus species native to Japan. The specific epithet (leiocarpa) comes from the Greek λεῖος leîos 'smooth', and καρπός karpós 'fruit'. It is a taxonomical synonym of Citrus aurantium.

Description
The fruit is oblate in shape, slightly ribbed, bright orange in color, very small, and very seedy, and for the latter two reasons it is not grown for commercial use. It ripens from October through November and has been cultivated since at least 1900. It may be monoembryonic. The tree is densely branched and has a broad crown and a short, straight trunk. The leaves are dark green and elliptical in shape.
Range & habitat
Besides Japan, it is grown in the United States, and other parts of East Asia including South Korea and China.
