Nom. Jap. Kono-watashi 1^-Z.iI%' 



In hortis Japonensis rarius culta. 

 I don't know whence this cultivated ])oar came from. Except 

 the stout and elongated nearly trailing branches and the rusty hairs 

 on the leaves, branches, flower-stalks and inside of calyx this is 

 nearest to Pyrus serotina. I have named in honour of Mr. Akio 

 KiKUCHi, the director of the Kanagawa Agricultural Experimental 

 Station and the author of Pyrus hondoensis, P. aromatica and P. 

 crassipes who are specially investigating on Pears.
