Summary

Describes case of two varieties of Russian wheat, the kubanka (or White Turkish) and the saxonka, which grow side by side with no intermediate varieties. As kubanka gradually yields place to saxonka, thinks an unusual tendency to jumping variation [saltation] operates; suggests CD urge some young botanist to investigate [see ML 2: 419–22].
