Remarks.
The taxon was recorded for North Korea (Gangwon-do, Hamgyeongnam-do, cf. Kim and Hwang 1991), but was not found in specimens examined. We suggest that all reports regarding the occurrence of this species in Korea and adjacent regions are erroneous and probably belong to M. apertifolia to which the species are similar in coloration and rounded leaf lobes, but differ in leaf margin characteristics, leaf sinus deepness, and stem cross section features, all of which are included in the identification key. In general, M. sphacelata is a rarity in East Asia and probably absent southward of 53°N (southern part of Kamchatka Peninsula). The records for Honshu Island in Japan are doubtful due to reported red pigmentation ( Kitagawa 1963) which is not known for this species from other parts of its range (cf. Schuster 1974).
