In a general way the description given thirty years ago by Downing will apply to the many seedling varieties found from the Atlantic to the Pacific. He wrote: "Fruit small, oval,about an inch long; skin purple, covered with thick blue bloom. Flesh melting, juicy, rather tart; separates partially from the stone. Season, September." In the north half of Iowa the. Danish Damson has most value on account of hardiness. This was introduced by H. Knudson of Springfield, Minnesota, and disseminated for trial by the writer. In milder climates what is known as French Damson and the Frogmore Damson have most value as budded trees. Domestica.

Deaton (Tobe's Gage)

Medium to large, roundish oval; color yellow with whitish bloom and scattering large yellow dots; stem medium, stout, in deep abrupt cavity; suture shallow. Flesh greenish yellow; very good. It seems to be identical with the Tobe's Gage, an old variety of Pennsylvania. Domestica.

Diamond (Black Diamond)

Large, oval; color dark blue with blue bloom; dots small; stalk short, stout; suture distinct, but shallow. Flesh yellow, coarse-grained, not very juicy; quality poor for dessert, but good for culinary use. Widely grown across the continent. Domestica.

Large to very large, oblong, egg-shaped, swollen on suture side; color somewhat darker than Lombard, and dark blue when fully ripe; dots prominent; stalk three-quarters of an inch long, slender, inserted in narrow shallow cavity; suture shallow. Flesh yellow, meaty; quality good; partial freestone. Season, early August. Mostly grown commercially on the west coast. Domestica.
