Abstract
Ophiopogon marmoratus L.Pierre ex L.Rodr. is treated as a synonym of O. regnieri Bois. Ophiopogon regnieri shows a wide variation especially in some leaf characters. Ophiopogon tonkinensis L.Rodr. differs from O. regnieri in some floral characters，though they appear to be closely related to each other. (Continued from J. Jpn. Bot. 74: 25-33，1999)
