%X Four species of Grimmiaceae growing in Tian shan glacier one were observed their micro structure and appearance character by paraffin wax section and scanning electron microscopy. It showed that no obvious protrusion of costa dorsum was in leaves of <em>Grimmia elatior</em> Bruth ex Bals et Dt Not . The ornamentation of surface stratum had longitudinal strips and the squamalike appurtenance was on the back leaves. The epidermal cells in stems of <em>Grimmia donniana</em> Sm.sink deeply.to form wavilness and the costa were thin dorsum with prominence.The costa of back andventral leave epidermal calls of <em>Grimmia pulvinata</em> (Hedw) Sm without microstereid are umbonate and plenty of starch grains were in stem and leave cells. The epidermal cells of back and ventral leaves of Grimmia tergestina Tomm.ex B.S.G were deepiy concave thick cuticular and rougae,larvating the concarve epidermal cells,abd costa protrude obviousy.These features will be a basis of taxonomy for Moss.
