Abstract: Two new species of the genus Epimedium (Berberidaceae) from China, E. pseudowushanense B. L. Guo and E. qingchengshanense G. Y. Zhong & B. L. Guo, are described and illustrated. Epimedium pseudowushanense, distributed from southeast of Guizhou to north of Guangxi, has been previously misidentified as E. wushanense T. S. Ying because of the similarity in their leaflet shape, but they are two distinct species because of the obvious difference in their flower structure. Epimedium pseudowushanense is possibly similar to E. mikinorii Stearn, a species from Enshi, Hubei, in having petals with a very slender spur and a wrinkled lamina, but differs in the spur shorter, only 10–15 mm long, the lamina smaller, the leaflets narrowly ovate to lanceolate, sparsely white villose and glaucous on abaxial side, the petals purplish or purple with yellow lamina, and the inner sepals broadly ovate or ovate, 8–13 mm long. Epimedium qingchengshanense G. Y. Zhong & B. L. Guo, known only from Dujiangyan, Sichuan, is one of the Epimedium species with long filaments and most similar to E. fargesii Franch., but differs by having smaller flowers, bigger, rounded petal lamina without lobes, and purple filaments.
