A Freak Calla
This Calla Lily, found on Mr. Burbank's grounds, gives a clear idea of the relation of the spathe to spadix. It will be seen that while the spadix bears the blossoms, the spathe is, in point of fact, a modified leaf twisted into a sort of cornucopia around it. Through some lack of balance in the heredity of the plant shown above, the spathe took back to the days, evidently, when this transformation was in the making.
