along the dorsal edge, somewhat ridged toward the base, and the 
surface obscurely roughened... 
Prunus subcordata is often only a shrub 3 to 10 feet high with crooked 
stem and branches. In moist fertile soils it grows to a height of 15 
to 25 feet. It often forms extensive thickets or clumps. ‘The bark. 
of the trunk is grayish brown, furrowed, and somewhat scaly; the 
main branches are rather thick and start out nearly horizontally 
from the trunk. The young twigs are reddish, either glabrous or 
pubescent, and marked with orange-colored lenticels. 
The species is found (fig. 1) in central Oregon and northeastern 
California, thence southward along the western slope of the Sierra 
Nevada to the Yosemite Valley, where it occurs at an altitude of 
4,000 feet, in the coast ranges of California in Lake County, in the 
hills east of Santa Rosa, and on Black Mountain, Santa Clara County. 
Prunus subcordata was originally described from the. upper valley 
of the Sacramento, where it appears to have been first collected by 
Karl Theodor Hartweg in 1836 or 1837. 
Prunus subcordata kelloggit does not appear to show any botanical 
differences from the type. The larger size of the tree and the larger 
and superior quality of the fruit ascribed to the proposed subspecies 
are not correlated with any other character; and these are variations 
that occur in all the species of the genus. The author of this sup- 
posed form says of it: 
The variety is abundant near Sierra City, Sierra Co., Cal., where along with the 
type the writer has observed it almost annually since 1867. It prevails generally 
in the more northerly parts of the state, and has long been observed and its superior 
qualities noted by my friend Mr. Sisson, of Strawberry Valley at the base of Mt. 
Shasta, where it grows plentifully along streams that course through rich meadow 
lands. Dr. Kellogg described it, though without giving it a varietal name, as early 
as 1859, in Hutching’s Magazine * * * [86]. 
Since Hutching’s Magazine is a somewhat rare publication, it may 
be of interest to quote what Dr. Kellogg writes concerning this plum: 
It is very probable that many of our readers who dwell in the principal mercantile 
cities are unaware that in the mountains of this state there are not less than two 
varieties of a very excellent wild plum. One is almost the size—although we have 
seen some much larger—and shape of that given in our engraving, the other is a Little 
smaller, oblong, and almost the shape and color of a damson when ripe. This latter 
variety has not yet been examined and classified by botanists; but if some of our 
friends who are coming to the city will bring a good specimen with them and leave it 
with us, we will see that this is done. 
Both varieties of this plum grow on low bushes and not on trees like other wild 
plums at the east, and are about the height and conformation of the illustration given 
on page 10. 
They generally grow in patches or groups, at the heads of ravines, at an altitude 
seldom less than 2,000 feet above the sea, and mostly in open localities adjacent to
