 There is no country in which the domesticated Plum 

 flora is so complex as in North America, for we nut 

 only grow the specific types of Europe and of Japan, 

 but also species that are peculiar to our own country. 

 In the northeastern st.ates and on the Pacific slope the 

 European or Domestica types are the leading Plums. In 

 these same areas and alsi. in the South and in parts 



of the mill .Mi;ii :,l I, :;i,,n, ill,- .Japanese Plums are

 are developed from wild species of the country, and 

 they are unknown in cultivation (except in botani- 

 cal or amateur collections) in any other part of the 

 world. These have been developed chiefly within a half 

 century, although a few varieties are older than this. 

 For a history of this evolution, see "Sketch of the Evo- 

 lution of our Native Fruits." 



The Plums cultivated in North America belong to the 

 following groups (see Priiiius): 



1. Domestica or European types, Prvvus (Jotnestirn. 

 Native to western Asia. Comprises the common or ohl- 

 time Plums, such as Green Gage, Lombard, Bradshaw, 

 Yellow Egg, Damsons, and the like. The leading Plums 

 from Lake Michigan eastward and north of the Oliin, 

 ami on the Pacific slope. Figs. 1851 to l^.SO are of 

 this species. Of late years, hardy races of I'limiis 

 domestica have been introduced from Russia. These 

 have value for the colder parts of the plum-growing 

 regions. Figs. 1853-5 show representative forms of the 

 Russian type. 



2. The Myrobalan or cherry-Plum type, Pniiinn cernx- 

 ifera. Native to southeastern Eumpe nr seutliwestern 

 Asia. Much used for stocks upon wliieii 1.. hml I'lums, 



and also the parent of a few nai 1 \arieties, as 



Golden Cherry; and DeCaradeuc and Marianna are 

 either offshoots of it or hybrids between it and one of 

 the native Plums. 



3. Japanese types, Pntmis friflora. Probably native 

 to China. The type seems to be generally adapted to the 

 United States, and will certainly be of great value to 

 111. ill the Smith aii.l \..iili. 'I'liis species first appeared

4. The Apricot or Simon Plum, Pninns ShnoniL 

 Native to China. Widely disseminated in this country, 

 but little grown except in parts of California. Intro- 

 duced about 1S81,

7. The Chickasaw types, Prnnns angustifolia (or P. 

 Chicasn). Native to the southern states, and there 

 cultivated (from southern Pennsylvania southwards) in 

 such varieties as Newman, Caddo Chief and Lone 

 Star.
