%X Karyotypes of Ophiopogon reversus (Convallariaceae) collected from four localities in Taiwan and one locality on Yonaguni-jima Island in the southern Ryukyus of Japan were reported for the first time. Those of O. jaburan collected from three major islands (Amami-oshima, Tokuno-shima and Okinawa-jima) of the central Ryukyus were also investigated for comparison. All plants of O. reversus and O. jaburan investigated were diploid (2n = 36) based on the basic chromosome number of x = 18. Among 36 chromosomes of O. reversus, one pair of short chromosomes with submedian centromeres had secondary constrictions at the proximal region of the long arms. Based on this character, O. reversus is cytologically distinguishable from O. jaburan, in which one pair of short metacentric chromosomes had secondary constrictions at the proximal region of the short arms.
