RemarksBoth The Japanese Pharmacopoeia and The Pharmacopoeia of People's Republic of China define O. japonicus as the original plant. Besids, in China, O. ohwii (Jap. Name: Sekkojanohige) and O. chekiangensis Kimura et Migo are circulated. The latter is cultivated in Zhejiang Province. Some say that it must be disinguished from O. japonicus because it has slender rhizome. Korean "Maimendong" is the enlarged roots of Liriope spicata Lour. (Jap. Name: Koyaburan) or L. platyphylla Wang et Tang., which is called "Tumaimen" in China. Its quality is not good.
