Ophiopogon clarkei* ， O. grandis* ， O. lushuiensis* ， O. zingiberaceu ♂， O. merr i/- lii* ，O.α caulis (=Chloopsis acaulis) * ， O. wallichianus (=Fluegge αwallichiana) ， O. bodinieri ， O. indicus and jacquemontian αare treated as synonyms of O. intermedius intermedius (new synonyms are asterisked). All the varieties of O. intermedius and O. wallichianus wallichianus described by Hooker (1892) are also treated as the same taxon as O. intermedius. intermedius. Don's O. spicatus may also be conspecific with O. intermedius ， as reported in in some previous papers. Ophiopogon intermedius is an exceedingly variable species with an an extensive r加 ge of distribution in Asia. (Continued from J. Jpn. Bo t. 75: 127-136)
