Zelkova serrata (Japanese zelkova, Japanese elm,[2] keyaki, or keaki; Japanese: 欅 (ケヤキ) keyaki /槻 (ツキ) tsuki; Chinese: 榉树/櫸樹 jǔshù; Korean: 느티나무 neutinamu) is a species of the genus Zelkova native to Japan, Korea, eastern China and Taiwan.[3][4] It is often grown as an ornamental tree, and used in bonsai. There are two varieties, Zelkova serrata var. serrata in Japan and mainland eastern Asia, and Zelkova serrata var. tarokoensis (Hayata) Li on Taiwan which differs from the type in its smaller leaves with less deeply cut serration on the margins.[4]
