| Abstract: | Studies on Dendrobium huoshanense show that the leaf is isobiateral,the stoma is quadrilateral,and only distributes in lower egidermis.40 collateral closed bundles scatter in the ground tissue of the stem. The velamon is composed by 8-9 layers of cells with reticulate thick cell wall. The radial vascular bundle of the root is tenarch without pith.The exodermis, endodermis and pericycle are all formed by 1 layer cell and all has parenchyma passage cell. |
