Ophiopogon japonicus (Thunb.) Ker Gaw l. and O. jaburan (Siebold) Lodd. are taxonomically taxonomically reinvestigated. The following taxa are treated as synonyms of 0. japonicus (new (new synonyms 訂 e asterisked): O. umbraticola Hance ， O. stolonifer H.Lev. & Vaniot ， O. argyi argyi H.Lev. ，Mondo longifolium Ohwi* ， O. chekiangensis K. Ki mura & Migo ，Mondo gracile gracile (Kunth) Koidz. var. brevipedicellatum Koidz. *， O. japonicus v紅 . umbrosus Maxim. *， O. japonicus var. caespitosus Okuyama* and Anemarrhena cavaleriei H.Lev. * Ophiopogonjaponicus Ophiopogonjaponicus here circumscribed occurs in China ， Korea and Japan. Meanwhile ， O. O. taqetii H.Lev. is treated as conspecific with O. jaburan ， as was done by McKean (1986). (1986). Ophiopogonjaburan occurs in Japan and Korea. However ， the distribution of this species species in the southern Ryukyu Islands needs further study. Fl owers of both O. japonicus and and o. jaburan 紅 e diurna l. These two species 訂 e regarded as closely related ， as they share share this unique flowering habit and some other similar features.
