A traditional medicine, Potentillae Chinensis Herba, the herbs of Potentilla chinensis Ser., has long been used to treat various inflammations and colds. This study aimed to provide information for herbal medicine discrimination by observing and describing the micromorphological structure of P. chinensis using a field-emission scanning electron microscope (FE-SEM). Two types of long and short conical strigose were sparsely distributed on the adaxial surface of the leaves. Conical strigose and floccose villi were densely distributed on the abaxial surface as a whole. In particular, the strigose of 200 ㎛ or more, and 500 ㎛ more were distributed in the main vein of the both surfaces and around them, respectively. Two types of long and short conical strigose were also distributed in the petiole and the outer side of the sepal. Partially long trichomes at the base and margins were observed on the inner side of the sepal. The type of the petal's epidermal cells appeared as tabular rugose on the outside and conical papillose on the inside. The achene, is reniform and ovoid in shape, the colliculate ornamentation, and their epidermal cells were irregularly arranged in pentagonal or hexagonal shapes. The obtained results secure primary data on the micromorphological structure of P. chinensis for future systematic works and provide information of Potentillae Chinensis Herba for accurate authentication.
