will certainly be of great value to both the south and north. 

 See our Bulletins 62 and 106 for full accounts of these plums. 



IV. The Apricot or Simon plum, Prunus Simonii. Native to 

 China. Widely disseminated in this country, but little grown 

 except, perhaps, in parts of California. See our Bulletin 51. 



V. The Americana types, Pnanis Americana. The common 

 wild plum of the north, and extending westward to the Rocky 

 Mountains and southward to the Gulf and Texas. Admir- 

 ably adapted to climates too severe for the domestica plums, 

 as the plains and the upper Mississippi valley. See our Bul- 

 letin 38 for accounts of all the native plums. 



VI. The Wild Goose or hortulana types, Prunus hortulana. A 

 mongrel type of plums, comprising such kinds as Wild 

 Goose, Wayland, Moreman, Miner and Golden Beauty. No 

 doubt hybrids of the last and the next. 



VII. The Chickasaw types, Prtinus angtistifolia (or P. Chicasa). 

 Native to the Southern states, and there cultivated (from 

 southern Delaware southwards) in such varieties as Newman, 

 Caddo Chief, and lyone Star. 



VIII. The Sand plum, Prjuius Watsoni. Native to Kansas and 

 Nebraska. A bush-like species, little known in cultivation. 

 A hybrid of this and the Western Sand Cherry is the Utah 

 Hybrid Cherry. See our Bulletin 70. 



IX. The Beach plum, Primtis viaritima. Native to the coast 

 from New Brunswick to Virginia. In cultivation represented 

 by the unimportant Bassett's American ; also as an orna- 

 mental plant. 



X. The Pacific coast plum, Prunus subcordata. Native to Ore- 

 gon and California. Sparingly known in cultivation, chiefly 

 in the form known as the Sisson plum (var. Kelloggii). 



With these ten types coming into cultivation in the rapidly 

 enlarging fruit zones of our immense country, who can forsee 

 what the final outcome as to types and varieties may be !* 



The remarks in the present paper are meant to apply only to 

 the domestica and Japanese plums, chiefly to the former. In

Survival of the Unlike," p. 418.
