Narrative

Raised from a seed planted by Lemuel Clapp of Dorchester, Massachusetts. Date of origin uncertain. Introduced by Ellwanger and Barry, 1895. Fruit medium or larger in size, obovate-obtuse-pyriform, regular in size and form. Skin reasonably smooth, greenish-yellow in color, often blushed, fairly attractive. Flesh white, medium fine, buttery but not melting, somewhat juicy. Sweet with pleasing flavor but not among the best in dessert quality. Late keeper, slow in ripening with long shelf life. Tree moderate grower, spreading in habit, very productive. Fairly susceptible to fire blight.

- H. Hartman, Oregon Agricultural Experiment Station, 1957
