%X We used paraffin sections and scanning electron microscopy(SEM) to observe the structure and surface micromorphological characteristics of the stems of 15 species of Pottiaceae that grown from the retreat of Glacier No.1. The stem of Pottiaceae was divided into two types with central axis and no central axes. The cell walls were thickened to different degrees. The stems of central axis were divided into three parts of epidermal, cortex and central axis. Stem epidermis cells are short with one layer, most of the cell wall protrudes outward, the surface is rough, and the surface decoration is mostly granular. The cortex is the largest area, most of which have differentiation of the inner and outer skin. The cell walls of most species gradually become thinner from the outside to the inside, and the cells are orderly arranged from small to large. The area of the central axis is also different, the cell wall corner is thickened. For no central axes, the cell walls were thickened to the same extent.
