%X The micromorphology of the leaf epidermis for 35 species and 2 varieties belonging to <em>Phleum</em> and its related genera of Poaceae were examined by scanning electron microscope. The intercostal long cells on both abaxial and adaxial epidermis of <em>Phleum</em> were long tubular or rhomboid, and the outlines of long cells were straight or curved. The shapes of silica cells in costal zones were nodular. Parallel-sided subsidiary cells were found. Prickles were frequently occurred in costal zones and absent or rarely seen in intercostal zones. No papillaes and micro-hairs were found. Meanwhile, a phylogenetic tree was constructed according to the characters of leaf epidermal micromorphology. <em>Phleum</em> and Poeae clustered together, which indicated that they had the closer relationship and distantly related to Aveneae, Agrostideae and Phalarideae. According to the micromorphology of leaf epidermises. <em>Phleum</em> should place into Poeae.
