sence of the calyx. They have apparently all been 

 derived from P. serotina, a common wild tree in the 

 woods on the mountains of the province of Hupeh in 

 central China, where I discovered it in 1900 and in- 

 troduced it into the Arnold Arboretum in 1909. 

 Though widely cultivated over the greater part of 

 China, Korea, and Japan it has not been found wild 

 except in central China. The other species (P. 

 ussuriensis) is more northern, being abundant in 

 central and northern Korea, and in Manchuria also; 

 it has recently been found wild in Japan in the region 

 around Mt. Fuji, and on the mountains of Shinano 

 province in mid-Japan. In this species the skin is 

 green, russet-green, or rosy; the calyx is usually per- 

 sistent but sometimes it is deciduous. Many varie- 

 ties of this Pear are grown in Korea and Manchuria, 

 and in the more northern parts of China. Around 

 Peking a variety having a delicious little apple- 

 shaped pear of a pale yellow colour is much grown 

 and is known as the White Pear. In parts of Japan 

 it is called the Stone Pear and is not esteemed. 

 There are a few hybrids between the Sand Pear 

 and the European Pear the best known being the 

 KiefTer and Le Comte. 



There are many other species of Pear-trees in Eur- 

 asia and the Orient which some day may be found of 

 value in the pear industry in Western lands. One
