Narrative

Fruit medium in size resembling Bartlett in form but somewhat smoother and more regular. Skin greenish in color, waxy, free from blemish, very attractive. Flesh fine, melting, juicy. fairly sweet, somewhat flat in taste with no outstanding flavor characteristics. Too soft to withstand commercial handling, short-lived in the ripe stage. Somewhat later than Bartlett. Tree vigorous, of good orchard habit, good foliage, productive. Fairly susceptible to blight. -- H. Hartman, 1957.
