Potentillae Discoloris Herba, the herbs of Potentilla discolor Bunge, is a traditional medicine in Korea and China. Numerous phytochemical studies have been conducted on this species; however, micromorphological studies have yet to be conducted. This study analyzed the micromorphological characteristics of P. discolor using a field-emission scanning electron microscope (FE-SEM) and presented a detailed description. Curved conical strigose were sparsely distributed on the adaxial surface of leaves; however, crispate and floccose villi were densely distributed on the abaxial surface. Additionally, densely distributed villi were observed on the petiole and the outer side of the sepals. Tabular rugose and conical papillose cells were identified on the outer and inner sides of the petals, respectively. The achenes had reniform to ellipsoidal outlines with colliculate sculptures. Such characteristics could have potential taxonomic significance for the genus Potentilla . The obtained results provide systematic data for the authentication of the Potentillae Discoloris Herba and establish a basis for future taxonomic work of the genus Potentilla.
