The anatomical study of the leaves, stems and roots of the rare and endemic tree species Davidia involucrata in our country found that the leaves were double-sided and stomatal, and distributed only in the lower epidermis with developed palisade tissues. Stem cortex and marrow parenchyma cells rich, secondary xylem catheter scattered, catheter end wall with ladder complex perforation. The primary xylem of the root is quadrilateral.
