Legend says a Chinese pistachio tree grew beside Confucius' tomb.
Tips
usage
Read jiē only in 楷树, the Chinese pistachio (also called the huánglián tree). This botanical reading is rare; the common everyday reading of the character is kǎi (regular script; model).
Left wood radical, the indexing component. The character began as a tree name; that botanical origin is why a 'tree' radical sits on a word now meaning 'model' and 'standard script'. Same family as 林 and 树.
Right 皆 supplies the sound, jiē, kept directly in the jiē reading and shifting to kǎi in this sense. It contributes no meaning here; the same phonetic appears in 谐.
