NOTES ON PLUM CULTURE. 
not valuable, being small and very acid. The color in all is 
dark, and in general much like the cherry. One tree, how- 
ever, produces fruits that are considerably larger and much 
better than any of the others. It is to be introduced and 
may prove an acceptable addition to the list of varieties. 
This tree is of spreading habit, in general appearance like 
varieties of Prunus Americana. Leaves medium in size, 
varying from ovate to lanceolate. Flowers small, produced 
in profusion. Fruit of medium size, spherical; color deep 
blue, with light bloom; flesh firm, of excellent flavor, 
possessing none of the astringency so noticable in the fruit 
of the other hybrids. The tree in bloom is illustrated by 
plate XIII, and a branch showing fruit in figure i, plate XIV. 
It is worthy of further trial. 
PRAIRIE FLOWER. {Primus horfulana Mirieri .) 
Represented by nine old trees of uncertain age, and one 
tree planted in 1894. The young tree fruited in 1897, the 
others have born for several years. The old trees are fully 
developed, as large as the trees of Miner, and of the same 
appearance. Leaves large, broadly to narrowly ovate-lance- 
olate, evenly crenate, lower surface pubescent, stalks long, 
stout, glandular. Fruit of medium size, round-oblong, ob- 
scurely pointed; color red on yellow ground, flecked all over 
with small light dots; suture evident; stem of medium length, 
stout; skin thin; flesh firm, sub-acid, of fair quality; stone 
cling, rather broad, short pointed at both ends, margin 
rather sharp, slightly roughened. Ripe September 2 1 . Very 
productive. 
PURPLE YOSEMITE. {Prunus Americana.) 
In character of tree very closely resembling the wild 
plant: very thorny, and irregular in habit. Leaves of 
medium size, ovate or obovate, acuminate, doubly serrate, 
dark green, pubescent below; stalks glandless, or occasion- 
ally with two small glands. Fruit large, round-oblong, 
flattened laterally; color deep purplish-red; skin thick; suture 
obsolete; flesh firm, of fair quality; stone cling, flat, rounded 
at the ends, rather rough, margins not sharp. Season 
.medium to late. Ripe September 24.
