 Prunus Pseudo-Cerasus (X %). No. 25. 



SUBGENUS IV. CHAM^AMYGDALUS (including Micro- 



cerasus). Dwarf Almond. 



Fruit small, either firm or juicy, glabrous or pubes- 

 cent: plant dwarf, with sessile flowers solitary or in 

 pairs preceding the Ivs., the stamens 20 or more, the 

 calyx-tube tubular: Ivs. conduplicate. 



36. incana, Decne. (C6rasus incdna, Spach. 

 Amygdalas incdna, Pall. A. ndna, var. incdna, 

 Loud.). Shrub of medium size: Ivs. small, the 

 petiole short and soft-hairy and glandless or bear- 

 ing glands at the very top, the blade obovate- 

 oblong, elliptic or lance-elliptic, short-pointed or 

 obtuse, finely sharp-toothed, white -tomentose beneath: 

 fls. mostly in 2's, appearing with the Ivs. or just in ad- 

 vance of them, light rose-color, about K in. across, the

 H. 1853:281. B.R. 25:58. Gt. 44, p. 243 (leaf ). 



37. nana, Stokes (Amygdalus 

 ndna, Linn.). RUSSIAN ALMOND. 

 Pig. 2002. Bush, 3 to 5 ft. high: 

 flowers solitary, appearing a little 

 in advance of the leaves, sessile, 

 pink and showy : Ivs. narrowly 

 elliptic or elliptic lanceolate, 2 or 

 3 in. long, thick and rather stiff, 

 scarcely pointed, lighter colored 

 and the veins prominent beneath, 

 smooth, the edges set with sharp, 

 spreading, saw-like teeth: fls. usu- 

 ally solitary, rose-color, nearly 1 in. 

 across, with or just preceding the 

 Ivs.: fruit small and hard, pubes- 

 cent, bitter, with a large, wrinkled, 

 sharp-pointed, somewhat cordate, 

 unequal sided pit. Russia and 

 Western Asia. B.M. 161. L.B.C, 

 12:1114. This plant has been in- 

 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 

 small-fruited form of the Apricot (P. 

 Armeniaca) has lately been in- 

 troduced as Russian Almond. 

 Primus nana is cultivated in 

 two or three forms. Var. cam- 

 pestriB has white fls. of larger 

 size. Var. Georgica has dark 

 rose-colored somewhat smaller 

 fls. and narrower, longer Ivs. 

 Var. Cochinchinensis 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. 



A. Plant low and bushy: Flowering Almonds. 

 . Jap6nica, Thunb. (P. nana of American gardens. 

 Sinensis, Hort. Amygdalus pumila, Sims). Figs. 

 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, % in. in diam., 

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

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

 1873, p. 457; 1874, p. 453; 1876:290; 1884:156; 1886, p.

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. 

 Carriere 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.

 last in having broadly ovate or obovate soft-hairy Ivs., 

 which are abruptly pointed, coarsely doubly serrate, 

 tending to be lobed above (on strong shoots): fls. soli- 

 tary and mostly in advance of the Ivs., pink or rose-col-
