"Ko-nara" (Quercus serrata) belongs to Fagaceae (the Beech family). It is a tall deciduous tree that is distributed southward from southern Hokkaido to Honshu, Shikoku, Kyushu in Japan, as well as the Korean Peninsula. This tree grows in broad-leaved forest on hillsides or mountains, and can reach 15-20 m in height. The barks are pale bluckish-brown and shallow-furrowed longitudially. The leaves are ovovate and alternate with large toothed edges and longer petioles than "Mizu-nara" (Quercus cuspidata). The timber is used for fuelwood or dead logs for Shiitake. The 17th-18th, 54th, and 60th-61st photos are insect goals.
