The "sakaki" ("Cleyera japonica") is a flowering evergreen tree, which is considered sacred in Japanese mythology. In the present day, Shinto shrines often plant it as a "sakaiki" (境木 "boundary tree") to demarcate sanctified space. "Sakaki" is written with the "kanji" , which graphically combines "boku" or "ki" "tree; wood" and "shin" or "kami" "spirit; god", compare "Shinboku" (神木 "sacred tree"). Carr (1995:11) characterizes 榊 as "a doubly exceptional logograph"; it is an ideograph "character representing an idea" (which is an infrequent type of logograph "character representing a word", see Chinese character classification), and it is a "kokuji" 国字 "national character; Japanese-made character" (rather than a typical "kanji" 漢字 "Chinese character" loanword).
