Narrative

This pear was entered in the Station records under the name Thornley for the reason that it was found as a chance seedling on the property of J. Thornley of Medford, Oregon. The name has not been officially registered. Fruit resembles that of P. Barry in shape and coloration but appears a little smaller in size. Flesh yellowish-green in color, very fine, juicy, melting, quite free of grit. Very sweet, rich, and spicy in flavor. Rates among the best in dessert quality. Probably too small in size and too unattractive in appearance to warrant recognition as a commercial variety. Tree of medium vigor, spreading in habit, moderately susceptible to fire blight. -- H. Hartman 1957.
