Although the biennial variety of MAelilotus alba has been known in the United States for a long time, the annual variety has been found only within recent years (28). The annual may be distinguished from the biennial variety in that the food and energy in the annual are used to form a main central vertical stem with smaller lateral branches, whereas in the biennial, although they form a central vertical shoot, greater emphasis is placed upon the production of numerous lateral branches. From buds on the crown of the biennial plant, lateral branches arise during the second season and produce numerous flowers. In view of the fact that the two varieties are functionally different, the present investigation was undertaken to ascertain whether any cytological differences exist between them.
