About
The character 桫 is a phono-semantic compound structured with the semantic component 木, meaning tree, and the phonetic component 沙, which provides its sound. It is employed almost exclusively in the binomial term 桫椤 to designate a specific genus of tree ferns. Etymologically, the character was devised to capture the phonetic element of the plant's name, and its usage has been narrowly confined to this botanical context without developing additional meanings.
