This species is not mentioned by Hemsley in his Index florae 

 sinensis, though Hooker in 1879 includes Yunnan in the distribution 

 of the species. Wilson's No. 1335 which is in ripe fruit agrees well 

 with typical P. pashia and the young plants raised at the Arnold 

 Arboretum from seeds of that number show exactly the kind of finely 

 and sharply serrate mostly deeply lobed leaves, figured by Decaisne 

 as the form occurring on suckers. No. 4132 differs in its much shorter 

 and tomentose pedicels, only about 1.5 cm. long, and in the generally 

 broader leaves mostly subcordate at the base; part of the fruits show a 

 persistent calyx. Whether this is a variety of this species or a distinct 

 species may be decided when the plants in cultivation flower and fruit. 



Pyrus -pashia was first introduced in 1825 into England from Nepal 

 or Kumaon ; in 1908 it was reintroduced by E. H. Wilson from western 

 China and distributed through the Arnold Arboretum. Possibly the 

 plant introduced in 1825 represents the following variety, as it is this 

 variety which is now found occasionally in European collections.

3 In the text the references to the type specimens of this species and of P. 

 granulosa are interchanged; "Pyrus (c)" belongs to P. granulosa and "P. 

 variolosa Trell. [sic] var." belongs to P. verruculosa.
