The Wild Goose varieties, now placed here, in the past have been considered hybrids more closely resembling _Prunus hortulana_ than any other species. But Wild Goose and some other varieties of its group are not to be distinguished from _Prunus munsoniana_ and beyond question belong in this species. The varieties in this division of Munsoniana are largely seedlings of Wild Goose, each variety possibly with a different male parent since Wild Goose seldom or never fruits unless cross-fertilized. Thus, of these plums, twelve are known seedlings of Wild Goose; seven others originated under cultivation; the origin of fourteen is not known and it is not certain that any beside Wild Goose came from wild plants. From such a record, and from the characters of the plants, it is probable that some of the Wild Goose varieties are horticultural hybrids, many of them from H. A. Terry of Iowa in whose work, with many varieties of several species, hybridity was the rule. Horticulturally, this is the most important group of native plums for the South; it contains a greater number of cultivated varieties than any other native species excepting _Prunus americana_, no less than sixty sorts being listed in _The Plums of New York_, some of which are deservedly the best known of the native plums for either home or market use. For dessert or the kitchen they are particularly valuable, having a sprightly vinous flavor making them very pleasant flavored to eat out of hand or when cooked. Their bright colors, semi-transparent skins and well-turned forms make them very attractive in appearance. Considering the juiciness of most of the varieties, these plums ship and keep well. Unfortunately nearly all of the varieties of this species are clingstones. This group hybridizes more freely than any other of the plums and there are a great number of promising hybrids of which it is one of the parents. Of all plums, these are most in need of cross-pollination, some of the varieties being nearly or, as in the case of Wild Goose, wholly self-sterile. While these plums are especially valuable in the Southern States, some of them are desirable in the North as well, where all will grow at least as far north as central New York. Plums of this species are occasionally but not often used as stocks. Some recommend them for stocks for low or wet lands. The fact that _Prunus munsoniana_ suckers very badly will probably preclude its use largely in propagating. The leading varieties under cultivation of this species are Arkansas, Pottawattamie, Robinson, Newman, Wild Goose and Downing, all of which are described in full and illustrated in colors in _The Plums of New York_. The first four of these have in the past been referred by botanists and pomologists to _Prunus angustifolia_ and the last two to _Prunus hortulana_. =20.= =PRUNUS MARITIMA= Marshall
