 This is tlie best Japanese Pear hitherto known. Though its fruit 

 is difficult to preserve on account of the richness of juice, it is the 

 nicest and has best flavour. In every respect it surpass the European 

 pears. It is said to have been raised from two parents which are kept 

 only by its raiser, yet we can point that at least one of its parents is 

 Pyrus lasiogyna. In crossing the present variety with other pears the 

 pubescence is always dominant.

P. tremulans and P. insulsa are one and the same variety of Pyrus 

 rufo-ferruginea, differing merely in the small serrations and more 

 glabrous leaves.
