Abstract: Applied paraffin wax section and scanning electron microscopy to observing and analysing the inner structure of stems and leaf, the cuticular wrinkles, papillae and midrib of the leaf. The results indicate that transverse section of stem is mutirhomboidal, the cuticulas of cuticle and ventral are thicker in Barbula asperifolia Mitt., the scabrous papillae is unforked, while top parts tilt to cell cave, cell wall of cuticle like splay stoma, scabrous papillae locate in it and Midrib distinct process. Transverse section of stem of Tortella humilis (Hedw.) Jenn. is ellipse, cuticle and mid-top venter are covered densely by scabrous papillae which are forked and protrude from cell cave and form a cluster, bent like a hook at the top, papillae reduce little by little under the leaf, with midrib broadish. Transverse section of stem of Mnium heterophyllum (Hook.) Schwagr. is pentagon, leaf cell are single and present unregular hexagon, whereas cell wall dent and become reticulation and midrib is red. Transverse section of stem of Hypnum plumaeforme Wils. is round, the cuticle and venter of are covered densely by rugged papilla that there is no appreciable distinction between them, top part of all scabrous papillae bend and tilt to stoma, present shade. midrib is short and ebb.
