More Evidence of Chrysanthemum Cousinship
The flowers shown above, selected from some of Mr. Burbank's Shasta experiments, have more the appearance of the chrysanthemum, almost, than of the daisy. It wtll be noted that the flower at the lower left gives evidence of doubleness to such an extent that the center has begun to fill up. Mr. Burbank has, in fact, produced some daisies in which the center is completely filled.
