A Metamorphosed Leaf
In the center above, an ordinary leaf of the Heuchera, or "wild geranium"; at right and left below, different types of crested leaves of the same plant developed by Mr. Burbank through selective breeding. The story of this modiflcation of a leaf, as told in the text, has peculiar interest. Doubtless many other plants have similar possibilities of development, and many an amateur should be stimulated to emulate Mr. Burbank's example; for the results of this particular experiment are at once novel and striking.
