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.

Rosa davurica Pallas. (Rosaceae.) 43887. Plants of 

 rose from Jamaica Plain, Mass. Presented by the Arnold 

 Arboretum. This is allied to the Cinnamon rose, and 

 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 ecae Aitchison. (Rosaceae.) 43888. Plants of 

 rose 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 Regel. (Rosaceae.) 43890. Plants 

 of rose 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.
