The genus Glycine L. has been divided into three sub-genera, namely Glycine L., Bracteata Verde ., and Soja (Moench) F. J. Herm. (Hymowitz, 1970). G.falcata of 1864 was the last of the true Glycine species to be described by Bentham (Hermann, 1962). G. falcata is one of the six species belonging to the sub-genus Glycine L. G.falcata appears to be restricted to Australia (Newell and Hymowitz, 1978).
