28 SEEDS AND PLANTS IMPORTED.

the northern limit of tlie species and the trees or bushes are 

 usually growing on very poor soil. The northernmost region in 

 which I found this type was from 75 to 100 miles north of 

 Seoul, Chosen." 



45827. " No. 64. Collected from typical trees at Kingmen, Hupeh 

 Province, China. The trees are very vigorous and often reach a 

 height of 60 feet and a trunk diameter of 2 feet. Pyrus 

 hetulaefoUa is abundant in the same region and grows under the 

 same conditions." 



45828. " No. 103. Obtained in the Chien Kang Mountains, northwest 

 of Ichang, China, at an altitude of 2.900 feet. The tree from 

 which this seed was taken was 30 feet high with a trunk diameter 

 of 18 inches and bore an enormous crop of fruit. The species is 

 very common in the mountains north and south of Ichang." 



45829 and 45830. Pyrtjs phaeocarpa Rehder. Malacese. Pear. 



45829. " No. 47. Collected near Tan Che Tse temple, about 30 miles 

 southwest of Peking, China. Tree wild, about 35 feet high, with 

 trunk 1 foot in diameter. The fruit, which is borne in clusters 

 of from one to five, is roundish, of russet color, from one-half 

 to three-fourths of an inch in diameter, two to three celled, and 

 has a deciduous calyx. Near Yangfan I saw trees of this species 

 from 50 to 60 feet high, with trunks 2* feet in diameter and 

 an enormous spread of branches. Young trees of this species, from 

 earlier introductions, when inoculated with pear-blight have proved 

 quite susceptible to the disease. It should be tested further, 

 to determine its resistance or susceptibility to blight and as a stock 

 for other pears." 



45830. " Collected 20 miles west of Peking, China. This form is simi- 

 lar to No. 47 [S. P. I. No. 45829], and the notes under that num- 

 ber will also apply to this." 



45831 and 45832. Pyrus seekulata Rehder. Malaceae. Pear. 



45831. "No. 100. Collected in the Chien Kang Mountains, 15 miles 

 northwest of Ichang, China, at an altitude of 3,700 feet. The 

 tree is of medium size and moderately vigorous. The fruit Ls 

 round, russet color, from half an inch to an inch in diameter, 

 three or sometimes two celled, and has a deciduous calyx. The 

 leaves are a very rich dark green and remain on tlie trees very 

 late in the fall. This type should be tested very thoroughly as a 

 stock for cultivated varieties. It has shown a marked degree of 

 resistance to pear-blight in our work at Talent. This type prob- 

 ably has given rise to some of the small cultivated varieties in 

 Central China." 



45832. " No. 105. Obtained at an altitude of 3,275 feet in the moun- 

 tains 15 miles northwest of Ichang, China. It is very similar to 

 No. 100 [S. P. I. No. 45831], except the shape of the fruit, which is 

 obovoid. To be tested for blight resistance and as a stock for 

 other pears." 



45833. Pyrus ussuriensis Maxim. Malaceae. Pear. 



" No. 60. Collected from wild trees at Shinglungshan. China. Trees of 



this species were formerly very abundant in this region, but as it has been
