Epimedium campanulatum CC 002079
Epimedium chlorandrum OG 94003
species from China
Large, elongated, very decorative leaves, speckled brown-red.
Large pale yellow flowers with yellow spur tips.
The pollen is green as in E. fargesii and E. pubescens.
E. chlorandrum is now treated as a synonym of Epimedium acuminatum.
Epimedium chlorandrum was described by Stearn (1997) as having the inner sepals being slightly ascending, and not closely appressed to the petals, and the anthers and pollen as being green. However, observations from the type locality of E. chlorandrum show that the diagnostic character of the inner sepals as not closely appressed to the petals is not stable, and E. acuminatum is also found having inner sepals being slightly ascending, with green anthers and pollen. There is no difference in morphology for the two species, thus, E. chlorandrum is here treated as a new synonym of E. acuminatum. Additionally, extensive specimen examination and field investigation demonstrate that it is incorrect for Stearn (1997) to recognize the color of anther and pollen as diagnostic features in Epimedium because, besides E. acuminatum, other Epimedium species (e.g. E. sagittatum, E. sutchuenense Franch., E. elongatum Kom., and E. leptorrhizum Stearn) with yellow anthers and pollen are also found with green anthers and pollen.
