This tree grows in mountain deciduous forests and can reach 2-3 m in height. The bark is blackish purple and has elliptic lenticles. The leaves are obovate to oboavate-elliptic, arranged alternately and have wavy coarsely toothed edges. The panicles are borne at the terminal branches, and the small, pale greenish yellow flowers bloom from May to July. The fruits are round drupes and ripen black in fall. The name is because the leaves are similar to "Ko-nara (Hahaso)" (Quercus serrata).
