Visually
檞 pairs the tree radical
木 on the left with the phonetic
解 on the right, naming a rare oak species and serving as a variant spelling of
槲. Component-data sources lack a reliable stroke-by-stroke split for this character, so it is treated as a single unit here. The
木 radical anchors it firmly in the botanical family alongside
槲,
樟 camphor,
桦 birch.
