About
The character "蔸", in its traditional form, is composed of the grass radical (艹) atop the component "兜", which primarily provides phonetic value but also carries a sense of something that holds or contains. Its core meaning historically relates to the root or base clump of certain plants, specifically grasses or shrubs, referring to the whole plant including its roots and the attached soil. From this concrete botanical sense, the character later developed a usage as a nominal measure word for clusters or clumps of plants, such as a "蔸" of rice or trees, quantifying them as whole rooted units.
