Note: E. macrosepalum described by Stern in 1938 (Stern, 1938, J. Linn. Soc. London (Bot.), 51: 485) from Primorye: "Primorye, Suchan River basin, Tigrovaya station" (type - LE), in our opinion, does not deserve species rank, as the indicated characteristics fall within the morphological variability typical of E. koreanum.
