NATIVE AMERICAN SPECIES OF PRUNUS. 338 
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 stewed 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. 
Just before the fruit 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 Merico, they do 
not always bear fruit two years 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 purposes, might be more 
hardy and serviceable than the other, as best adapted to their 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 any characters by which a distinct form might be 
distinguished. 
PRUNUS SUBCORDATA HYBRID. 
A variety named Glow, recently originated by Luther Burbank, 
is described by the originator as a combination of Prunus triflora, 
P. maritima, P. americana, P. subcordata, and P. ngra. 
Prunus 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 Klamath 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. 
Prunus Horturana Bailey. 
Prunus hortulana Bailey, 1892, in Gard. and Forest, v. 5, p. 90. 
Prunus hortulana waylandi Bailey, 1901, Cycl. Amer. Hort., v. 3, p. 1450. 
Leaves oblong-obovate acuminate (PI. III, fig. 1) to oblong-oval 
or oblong and acuminate, rarely oblong-lanceolate, mostly 7.5 to 11 
em. long, 2.5 to 4.5 cm. broad, usually rather abruptly rounded at the 
base, yellowish green, glabrous and somewhat lustrous above, pale 
green and pubescent below, with tawny hairs at least along the 
midrib and lateral veins, the pubescence usually tufted in the
