| Abstract: | This paper deals with anatomy of root, stem and leaf of Nyssa sinensis Oliv. . The results show that phloem fibers fasciculate circumaviate the periphery of the phloem on stem. The vessel cavities are not circularly distributed and single exists on the secondary xylem. The secondary xylem is diffuse - porous wood. Axial parenchyma and pith rays store goods in autumn. Epidermic hair on upper stem are rich. Collenchyma cells in the cortex and parenchymatous cells in pith are rich and primary structure on root so on. Leaf of Nyssa sinensis Oliv. is bifacial.The anatomical features of leaf shows that Nyssa sinensis Oliv. is a kind of mesophyte. |
