摘要：
Two samples from Michigan and Indiana were compared. The Indiana sample had significantly more bracts and flower arms than the Michigan. Even numbers of flower arms are more frequent than odd. For the Indiana sample the correlation between the number of bracts and of flower arms is + .624. Regression is linear. The average number of flower arms per bract is 4.93 for the Indiana sample and 428 for the Michigan.
