IT REALLY IS AN “EVER-SPORTING” VARIETY 
This: Boston fern shows variations in size and shape of leaflets in every part of the plant. 
It is a curiosity to the geneticist, but almost worthless from the standpoint of the practical 
breeder, because these small variations will probably not “breed true.’’ Frequently, 
however, a whole plant varies from its parent in some striking way; and such sports 
as that are perpetuated and form valuable new varieties. (Fig. 22.)
