NATIVE AMERICAN" SPECIES OF PRUNUS. 33 



pine forests, but not directly in it. The bushes are found near to each other, and the 

 two varieties frequently grow in the same group, though not from the same root. 



Both are excellent edibles, although those that are round are the first ripe and 

 better, eaten as fruit or ste^^ed as sauce, and preferred by some palates; but when the 

 oblong plum is thoroughly ripe, its rich acetous flavor, in our estimation, far excels 

 the other and makes a delicious preserve. 



JuBt before the fi-uit is fit for use, a large proportion of its leaves drop off, when, by 

 drawing the hand up the small twiglike boughs, an immense quantity can be gathered 

 in a brief space of time. 



For some unexplained reason, like the coffee tree of northwestern Mexico, they do 

 not always bear fruit two yeai's successively. 



These wild plums could be cultivated to advantage in our gardens and would make 

 a pleasing variety of fruit in our markets; and for grafting pm-poses, might be more 

 hardy and serviceable than the other, as best adapted to then- native soil and climate, 

 especially in a mountainous region. 



The differences described for this subspecies are variations that 

 occur in practically all the species of the genus and are horticultural 

 rather than botanical in their nature. A careful study in the field 

 also failed to reveal an}^ characters by which a distinct form might be 

 distinguished. 



Peunus Subcordata Hybrid. 



A variety named Glow, recently originated by Luther Burbank, 

 is described by the originator as a combination of Prunus trijlora, 

 P. maritima, P. americana, P. subcordata, and P. nigra. 



Peunxjs Subcordata Oregana (Greene) W. F. Wight. 



Prunus oregana Greene, 1896, in Pittonia, v. 3, pt. 15, p. 21. 



Leaves oval or ovate, about 3 cm. long, pubescent, at least on the 

 lower surface; fruit pubescent even when mature, otherwise similar 

 to the species. 



Originally described from specimens collected in 1893 on the 

 Klamath Indian Reservation, in southeastern Oregon, it has since 

 been collected near KHamath Falls and in the Sprague River Valley. 

 Since this differs from Prunus subcordata only in the fruit being 

 more or less covered with pubescence, it is not considered worthy 

 of specific rank. 



Prunu.s Hortulana Bailey. 



Prunus Jiortulana Bailey, 1892, in Gard. and Forest, v. 5, p. 90. 



Prunus hortulana vmylandi Bailey, 1901, Cycl. Amer. Hort., v. 3, p. 1450. 



Leaves oblong-obovate acuminate (PI. Ill, fig. 1) to oblong-oval 

 or oblong and acuminate, rarely oblong-lanceolate, mostly 7.5 to 11 

 cm. long, 2.0 to 4.5 cm. broad, usually rather abruptly rounded at the 

 base, yellowish green, glabrous and somewhat lustrous above, palo 

 green and pubescent below, with tawny hairs at least along the 

 midrib and lateral veins, the pubescence usually tufted in the
