Western Hupeh: Hsing-shan Hsien, thickets, alt. 1300-1600 m., 

 May and December 1907, E. H. Wilson (No. 779, type); north and 

 south of Ichang, alt. 600-1300 m., October 1907, E. H. Wilson (No. 

 479). 



This species seems to be most closely related to P. serotina Rehder 

 which is easily distinguished by the setosely serrate, generally longer 

 leaves, by the larger flowers with usually 5 styles and long-acuminate 

 sepals and by the larger fruit. The Japanese P. Uyematsuana Makino 1 

 seems to be most nearly related to P. serrulata; according to the 

 description it differs from it in the often subcordate leaves and in the 

 disk which is described as villose by Koidzumi; styles 3-5. 



Pyrus serrulata was introduced by E. H. Wilson and seeds have been 

 distributed through the Arnold Arboretum.

 griseis glabris vel fere glabris. Folia chartacea, elliptico-ovata vel 

 oblongo-ovata, in acumen longum -sensim attenuata, basi plerumque

 incurvis demum patentibus sinubus apertis saepe fere rectangulis,
