REHDER. — CHINESE SPECIES OF PYRUS. 233 



tainty without flowers or fruits; in fruit, however, the persistent 

 calyx of the ovate yellow fruit of P. ovoidea presents a good character, 

 and the flowers of P. ovoidea may be distinguished by the styles being 

 pubescent at the base. Wilson's No. 2977, of which the fruit is not 

 known, differs from the type in its broader ovate or broadly ovate 

 leaves with more appressed teeth and may represent a distinct variety 

 or even another species. Henry's No. 5875 has the fruit pyriform and 

 may belong to the following variety. Henry's No. 5299 is in flower 

 only and agrees with this species in its glabrous styles; both specimens 

 of Henry may be from cultivated plants. 



This species was introduced by E. H. Wilson in 1909 and seeds were 

 distributed by the Arnold Arboretum. According to a note received 

 two years ago it is growing in the Botanic garden at Glasnevin. 



This pear and probably other brown-fruited species are called by 

 the Chinese tang-li.
