NOTES ON PLUM CULTURE. 
39 
pubescent, glandular. Fruit small, round, dark purplish-red, 
bloom rather thick, stem of medium length, stout; skin 
thick; flesh of fair quality; stone semi-cling, oval, strongly 
convex on the sides, sharp on the edge but not margined. 
Ripe September it, Tree productive, but fruit too small to 
be ranked as valuable. 
KIC K A POO. (Primus Americana.) 
Planted in 1804. Not yet fruited. Trees of slow growth 
and straggling habit. Leaves large, broadly lanceolate, 
sharply and irregularly serrate, stalks glandular. 
KOPP. (.Prunus Americana.) 
Trees of good form and fair vigor, producing some 
drooping branches. Leaves large, dark green, sharply ser¬ 
rate; stalks red, pubescent, mostly glandless. Fruit medium 
to small, round, deep red, shading into the green ground, 
this mottled with white dots; skin thick; flesh firm, of good 
sub-acid flavor, sweet when fully ripe; stone nearly free, ob¬ 
long, pointed, strongly convex, smooth. Ripe September 
1. A productive variety. 
LATE ROLLINGSTONE. (Pi '•units Americana.) 
Trees of moderate vigor, forming round compact heads. 
Leaves of medium size, obovate-oblong, short acuminate, 
irregularly and unequally crenate; young shoots red, smooth, 
shining; stalks glandular, pubescent. Fruit medium in size, 
round, flattened at both ends, deep red, shading into light 
red; stem of medium length; skin thick; flesh firm, of excel¬ 
lent quality. Stone cling, broad-oval, sides moderately con¬ 
vex, smooth. Ripe September 11. Not to be distinguished 
from Rollingstone. Even in time of ripening there appears 
to be no difference here. 
LE DUC. (Prunus Americana.) 
The trees planted in 1894 are still rather small, but 
stocky and well-formed; they fruited heavily in 1897. This 
year they bloomed full, but matured a very light crop. 
Leaves large, light green, sharply serrate; stalks glandular.
