Pyrus nambuana is an individual of Pyrus aromatica having 

 smaller fruits. The leaves become often roundish in our type and the 

 mode of serrations concords perfectly to ours. Dr. Koidzumi says 

 ' foliis ab initio fere glabris ', but in his type specimen having adult 

 leaves lias hairs sparingly on the pedicclls and the costcC, by v^'hieh 

 the pubescence of the younger plants may be imagined. Pyrus jucunda 

 has liairs too along the base of costcE even in its adult stage.
