Abstract
THE family Theligonaceae has one genus Theligonum L. (= Cynocrambe Tourn.) in which four species have been reported: T. japonicum Okubo and Makino, T. macranthum Franch., T. cynocrambe L. and Cynocrambe formosana Ohwi. Two of these species have been cytologically examined previously by other workers. Schneider1 reported that T. cynocrambe, a Mediterranean species and an annual, had a somatic chromosome number of 2n = 20 and a meiotic count of n = 10. In contrast to this, Sugiura2 found that T. japonicum, a perennial from Japan, had a meiotic count of n = 11. He did not report on the somatic chromosomes of this species.
