264 WILSON EXPEDITION TO CHINA 



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

 chiefly in its serrulatC; not setosely serrate, generally broader leaves and in the 

 smaller flowers with usually 3 or 4 styles and shorter sepals and in the smaller 

 fruit.

Pyrus Calleryana is a widely distributed species, and according to Wilson it is 

 common in western Hupeh from river-level up to 1500 m. alt. It is easily recogniz- 

 able by its comparatively small crenate leaves glabrous or nearly glabrous like the 

 inflorescence and by its small flowers with 2, rarely 3 styles. Wlien unfolding most 

 specimens show a loose and thin tomentum on the underside of the leaves which 

 usually soon disappears, but in No. 1662 from KuHng even the fully grown leaves 

 are loosely rusty tomentose on the midrib beneath. In No. 415^ the leaves are 

 longer, generally ovate-oblong, the pedicels are verj^ long and slender, about 3-4 cm. 

 long, and the sepals are mostly long-acuminate. The fruits of No. 556^ are rather 

 large, about 1-1.4 cm. in diameter, but a fruit examined proved to be 2-celled. 



A picture of this tree will be found under No. 669 in the collection of Wilson's 

 photographs and also in his Vegetation of Western China, No. 424.
