Abstract:The anatomy of the roots, stems and leaves of Bowenia spectabilis Hook. ex Hook. f were studied. The primary structure of roots consists of epidermis, cortex and stele. Primary xylem is diarch. There are a large number of parenchyma cells with abundant starch grains in stems. The vascular bundles are collateral bundle. There are 5-8 vascular bundles in petioles and arranged in the shape of arch. Cuticle of the upper epidermis is thicker than that of the lower one, and stomata are restricted to the lower epidermis. There are small veins in mesophyll of pinnae. The xylem in roots, stems and leaves mainly consists of spiral and reticulated or pitted tracheids, and small amount of fibers. The tracheid wall in stems appears convexo-concave, and some tracheids are forked or branched.
