 troduced into this country recently 

 as a fruit plant, although it pos- 

 sesses little merit for that purpose.. 

 It is cultivated in Europe for its 



flowers, and it has been thought 1999. Prunus Avium,

gardens belongs to it; but our Flow- 

 ering Almonds are Prunus Japonica 

 and P. triloba, a correction which 

 was made in the revised edition of 

 Gray's "Field, Forest and Garden Bot- 

 any." This Russian Almond is very 

 hardy, enduring the climate of the 

 northern prairie states, where it ripens 

 its little almond-like fruits in July. A 

 "■-fruited form of the Apricot (P. 

 Armeniaca) has lately been in- 

 troduced as Russian Almond. 

 Prunus nana is cultivated in 

 two or three forms. Var. cam- 

 p^stris has white fls. of larger 

 size. Var. Ge6rgica has dark 

 rose-colored somewhat smaller 

 fls. and narrower, longer Ivs. 

 Var. Cochinchin^nsis is a larger 

 plant with white fls. 



Subgenus V. Amygdalus. 



Almonds and Peaches. 

 Fruit sessile, large, mostly 

 pubescent : fls. solitary from 

 lateral buds on the previous 

 year's growth, appearing in ad- 

 vance of the Ivs., the latter conduplicate in the bud.

 2002, 2003. Bushy plant, rarely over 5 ft. high : Ivs. ovate- 

 lanceolate to oblong-lanceolate, acuminate, not at all in- 

 clined to be lobed, glabrous or nearly so, very strongly 

 veined beneath, closely and almost obtusely serrulate: 

 fls. solitary or in 2's and 3's, rose-colored or blush, 

 stalked (the stalks lengthening), appearing with the 

 Ivs.: fr. globular or short-oblong, 3^ in. in diam., 

 smooth and shining, wine-red. Cult, from Japan, but. 

 probably native to China. B.M. 2176. R.H. 1852:301;

spring. Hardy. It is 

 known in gardens 

 only in the double 

 form. There is con- 

 siderable doubt as to 

 the application of the 

 two names P. Japon- 

 ica and P. Sinensis. 

 Carri^re supposes 

 (R.H. 1874, p. 451) 

 that there are two 

 species, and he says 

 that the true P. Si- 

 nensis is worth culti- 

 vating for the edible qualities of its fruit as 

 well as for its flowers. Until the question is 

 cleared up by further investigations of abo- 

 riginal types, the writer prefers to leave the 

 subject as above, thereby agreeing with most 

 writers on these plants.
