What is Orixa japonica

Orixa japonica (scientific name: Orixa japonica) is a deciduous shrub in the genus Orixa of the family Rutaceae, native to Japan and China. In Japan, it grows wild under forests in the mountains of Honshu, Shikoku, and Kyushu. The tree is 1 to 3 m tall and has grayish-brown bark. The leaves are glossy green, 5-12 cm long, 6 cm wide, and ovate. It is dioecious, and the male flowers are yellow-green, 2-5 cm long, and 0.7-1 cm in diameter, and the inflorescences are produced from April to May. Male flowers are borne in racemes of up to 10 flowers. The female flowers are unisexual, with a single flower. After flowering, the capsule bears four divided fruits. The name of the flower comes from the peculiar odor of its branches and leaves. Since it is a member of the mandarin family, it is a food plant for the mountain crow swallowtail butterfly (scientific name: Papilio maackii).
