Other modifications of flowers are sometimes known as doubling. For ex- ample, double dahlias (Fig. 232), chrysanthemums and sunflowers are forms in which the disk flowers have developed rays. The snow- ball is another case. In the wild plant (Fig. 236) the ex- tei'iial flowers of the cluster are large and sterile. In t])(^ cultivated plant (Fig. 237) all the flowers have be- come large and sterile. Hy- drangea is a similar case. 236. The wild or original form of the snowball.
