| Abstract: | The stem of the Vaccinium Uliginsum distributed at the elevation of 800-870 metres were observed anatomically. It turned out that the secondary xylem beloned to the diffuse-porous wood, especially the apotrac-heal wood parenchyma.The secondary phloem is composed of the dicp-tyletpn-wood type sieve tubes without companiofl cell aad phloem pare nchyma. |
