A Seedling Pear
This is a seedling pear that departs from the ideal shape, but which has many other qualities that highly commend it. It is large, and of luscious quality of flesh. Owing to its form, and to its lack of color, however, it has not been introduced, but has been used in further breeding experiments in the attempt to develop an ideal pear.
