Assistant In Plant Breeding at the Central Experiment 
Farm, Ottawa, tells me the three varieties of Russian 
pears constitute a part of an original Introduction 
by the late William Saunders, twenty-five or thirty 
years ago. Out of a large number of pears brought in 
from Russia, the following three varieties are the 
only survivors. They have proved to be very hardy as 
far as cold resistance Is concerned, and have also 
proved, in a large measure, blight resistant. I saw 
the three trees growing while at Ottawa last Septem- 
ber; they were vigorous specimens, the trunks being 
eight to ten inches in diameter, and they had a fine 
growth of wood and foliage. I saw no evidence of 
blight on the trees. The fruit of all "three varieties 
is said to be fairly good. They here take on all the 
usual characteristics of the Russian types." (B. T.

is found in Manchuria, Dahuria and Sakhalin. It has 
slender, . straight prickles. The flowers are purple 
and the fruit scarlet. (Adapted from Rehder, in Bailey, 
Standard Cyclopedia of Horticulture, vol. 5. p. 2998.) 
Rosa eeae Ait chl son. (Rosaceae.) 43888. Plants of 
ro»e from Jamaica Plain, Mass. Presented by the Ar- 
nold Arboretum. A very spiny shrubby rose, from Turk- 
estan, flowering in early summer with an abundance of 
small, deep yellow flowers. Recommended for hybrid- 
ization to create perfectly hardy yellow roses. (Adap- 
ted from note of Prank N. Meyer.) 
Rosa fedtschenkoana Re gel . (Rosaceae.) 43890. Plants 
of ro$e from Jamaica Plain, Mass. Presented by the Ar- 
nold Arboretum. A very handsome species from the 
Turkestan and Kokand regions of central Asia. It is 
a much-branched, very prickly shrub, with compound 
leaves 4 to 5 inches long, and large white flowers 
occurring singly or as many as four in a cluster. The 
red fruits are somewhat pear-shaped. When introduced 
in England this rose developed into a rambling, free- 
growing shrub, which flowered in the month of June.
