opened up for settlement during the past five years and as the soil is well 

 suited to agriculture, most of the trees have been destroyed. However, 

 many trees are still left, especially along the margins of the valley, in 

 the canyons, and along the streams. These trees attain a very large size, 

 often reaching 75 feet in height and 2\ feet in diameter. The fruit is 

 roundish or slightly flattened, from 1 to \\ inches in diameter, greenish 

 in color, with gritty flesh and sour flavor. Earlier introductions of this 

 species made by Mr. Frank N. Meyer have shown greater resistance to 

 pear-blight than any other species in the experiments at the Oregon sta- 

 tion. It appears to be very promising as a stock for cultivated pears in 

 very cold regions in this country, in regions where blight attacks the roots 

 and trunks of the trees, and in breeding hardy and blight-resistant vari- 

 eties. It has given rise to some of the best cultivated varieties of north- 

 ern China." 



45834. Pyrus sp. Malacese. Pear. 

 " No. 46. Pin li, or Ping li. Very similar to small Suan li [S. P. I. Nos. 



45846 and 45847]. These seeds were obtained from fruit grown near the 

 Chien Shan Mountains, near Lishan, Manchuria. This is a very popular 

 cultivated variety in the Chien Shan region and seems to be well adapted 

 to the conditions there. The fruit is small, varying from li to li inches 

 in diameter, roundish or slightly flattened in shape, and greenish yellow 

 in color, with often a blush on one side. It ripens during September and 

 possesses a very agreeable and refreshing tart flavor. This variety un- 

 doubtedly has been derived from P. ussuriensis, which it resembles in tree, 

 leaf, and fruit character. While the fruit has the tart flavor of that 

 species, it is of very much better flavor, and the flesh is softer than in the 

 wild forms. The calyx is always persistent, open, and with distinctly 

 spreading lobes. This variety will be thoroughly tested for blight resist- 

 ance, and if it shows the marked degree of resistance characteristic of 

 P. ussuriensis it should prove of great value, especially in breeding work." 



45835. Pyrus sp. Malacese. Pear. 

 " No. 112. Pin li. From Mukden, Manchuria. . Identical with No. 46 



[S. P. I. No. 45834]." 



45836. Pyrus sp. Malacese. Pear. 

 " No. 109. Shampa li. A cultivated variety grown in the Chien Shan 



Mountains, near Lishan, Manchuria. The fruit is small, yellowish when 

 ripe, with a persistent calyx. It probably belongs to P. ussuriensis and 

 for this reason should be thoroughly tested as a stock." 



45837. Pyrus sp. Malacese. Pear. 

 " No. 111. Shampa li. From Mukden, Manchuria. Identical with No. 



109 [S. P. I. No. 45836]." 



45838. Pyrus sp. Malacese. Pear. 

 "No. 110. Shu li. Another cultivated variety from Liaoyang, M.an- 



churia. Similar to Shampa li. Undoubtedly a cultivated form of P. 



ussuriensis."
