to the next joint above. It is prone to fall down from the effects of high wind, 

 is comparatively soft, and furnishes, when mature, a juice of high sucrose 

 and purity. It is a comparatively hardy cane and will give remunerative crops 

 on soils and under conditions where many other canes would fail. While 

 not immune to the attacks of insects and diseases, it is among the canes which 

 most successfully resist them." (Crawley.)

From Jamaica Plain, Mass. Presented by Mr. Jackson Dawson, superin- 

 tendent, Arnold Arboretum. Received December 8, 1914. 



" Pyrus bendaefolia was obtained from Dr. Bretschneider from the mountains 

 near Peking, China, and was sown at the Arboretum in 1882, so that our plants 

 are about 31 years of age. (Dawson.) 



"A slender, quick-growing, graceful tree, 20 to 30 feet high; young shoots 

 covered thickly with a gray felt which persists the whole of the year. Leaves 

 ovate or roundish ovate, 2 to 3 inches long, li to 1£ inches wide ; long pointed, 

 tapered or rounded at the base, regularly and sometimes rather coarsely 

 toothed ; downy on both surfaces at first, remaining so on the veins beneath 

 throughout the season; dark green, smooth and lustrous above; stalk 1 to 14. 

 inches long, .gray felted like the shoot. Flowers 8 to 10 together in a corymb, 

 white, each about three-fourths inch across, on a downy stalk three-fourths 

 to 1 inch long; calyx downy, its short, triangular teeth falling away from the 

 small roundish fruit, which is about the size of a large pea, grayish brown with 

 white dots. Native of North China; introduced to Kew in 1882 through seeds 

 sent by the late Dr. Bretschneider. The chief characteristics of the tree are 

 its quick graceful growth and small fruits not crowned by calyx teeth. Its 

 fruit would appear to be of no value, but the tree is used by the Chinese as a 

 stock on which they graft fruiting pears." (W. J. Bean, Trees and Shrubs
