About
The character "椤" derives from its traditional form "欏", which is a phono-semantic compound consisting of the tree radical "木" and the phonetic component "羅". Historically used to name trees such as the horse chestnut, its application later narrowed to specific botanical references, most notably in the compound "桫椤" for tree ferns. The modern form "椤" retains the tree radical while incorporating "罗", a streamlined version of "羅", which continues to serve a phonetic function without altering the character's enduring association with plant terminology.
