I start out with a couple web links I found, showing Epimedium in the wild in China. This particular site has 5 species listed; I'm featuring two of their links. The first is to Epimedium brevicornu, with some nice photos:

Next is E. grandiflorum:

The site also shows a plant listed as E. pubigerum, but the photos themselves have watermark captions as Epimedium hunanense, yet the photo depict neither species! Looks more like the starry white flowers of E. stellulatum or pubescens (my guess is, it resulted from confusion between the similar names of pubigerum and pubescens. The moral is, doesn't trust everything found on the internet; lots of bogus misinformation out there.
