Abstract: The morphological structure of leaf epiderm from 36 representative spcie in of Sect. Absintnium DC, Sect. Abrotanum Bess, Sect. Artemisia, Sect. Dracumculus Bess, and Sect. Latiobus Y.R. Ling from Artemisa were obserred in detail using scanning electron microscope, All the cpidermal cells varied in size and shape. The hypodermis had stoma. The shapes of the stoma were round.ovate and ovai. The types of stoma were anomocytac stoma. Anisocytac stoma and actinocytic stoma. The epiedrm of most plants had epidermal cell hain hair. The deffernce in these microstructural characters among groups may be of importance in taxonymy and ecology.
