After this class the frequency rises again and attains a secondary maximum in the age-class 67°5-72°5. (c) Table III. The numbers of stigmatic rays on a number of Shirley poppies were counted. As the range of variation is not great, the unit is taken as the class-interval. The frequency- distribution is given by the following table.
