 1910, W. Purdom (No. 328); Poa ting Fu plain, 1909, W. Purdom. 

 Hupeh: without precise locality, A. Henry (No. 1654). 



Henry's specimen from Hupeh differs from the type in its broader 

 and somewhat larger leaves. 



This species was first introduced in the sixties by G. E. Simon 

 to the Museum at Paris unintentionally as stock of a grafted Chinese 

 pear. In 1882 it was introduced again to the Arnold Arboretum by 

 Dr. Bretschneider from the mountains near Peking. 



This pear is called by the Chinese t'ao-li (pea -pear).

Pyrus Calleryana is a widely distributed species and seems not 

 uncommon on mountains at an altitude of from 1000 to 1500 m. 

 It is easily recognizable by its comparatively small crenate leaves, 

 like the inflorescence glabrous or nearly glabrous and by its small 

 flowers with 2, rarely 3 styles. ^Yhen unfolding most specimens 

 show a loose and thin tomentum on the under side of the leaves 

 which usually soon disappears, but in No. 1662 from Kuling even 

 the fully grown leaves are loosely rusty tomentose on the midrib
