A taxonomic revision of three Chinese spurless species of genus Epimedium L. (Berberidaceae).

ABSTRACT: Due to some common or similar features (e.g., small leaf, spurless, yellow flower), three Chinese species of the genus Epimedium (Berberidaceae), E. ecalcaratum, E. platypetalum, and E. campanulatum, are controversial based on morphological characteristics. In the present study, the descriptions of morphological characteristics for the three species were revised based on extensive studies and observations both in field and in herbaria. In general, E. ecalcaratum has long creeping rhizomes 1-3 mm in diameter, two alternate or opposite trifoliolate leaves, 7-14 flowers, and petals obovate and apex subacute. Epimedium platypetalum has short or long-creeping rhizomes 1-3 mm in diameter, one trifoliolate leaf, 2-6 flowers, and petals oblong and apex rou
