Epimedium brachyrrhizum CPC 940447
Very similar to E. leptorrhizum, but with shorter and thicker rhizomes.
Discovered in the mid-'90s in the Chinese province of Ghuizhou. Grows there at altitudes of 600-1500 m.
Since 2015 E. brachyrrhizum is treated as a synonym of E. leptorrhizum.
Stearn (1997) published Epimedium brachyrrhizum, which had been only known from the type locality. In the protologue for E. brachyrrhizum, the major difference between E. leptorrhizum and E. brachyrrhizum was that the former had a very slender elongated rhizome while the latter bore a more compact clump-forming rhizome. However, examination of a series of E. leptorrhizum specimens shows that its rhizome is often slender and long-creeping but occasionally thicker and compact. In addition, we observed E. leptorrhizum and E. brachyrrhizum in herbaria, the field, and gardens, and did not observe any associated floral or foliar differences between the two species. E. brachyrrhizum is reduced here as a new synonym of E. leptorrhizum.
