Phyllary information


In botanical terminology, a phyllary, also known an involucral bract or tegule, is a single bract of the involucre of a composite flower.[1][2][3] The involucre is the grouping of bracts together. Phyllaries are reduced leaf-like structures that form one or more whorls immediately below a flower head.[1]
