Juglans 281 



acute angle, small, ovoid, pubescent ; frequently two superposed. Pith large, brown, 

 with narrow chambers and thick plates. 



Distribution 



According to Maximowicz it occurs throughout the whole of Japan, there being 

 large trees around temples at Hakodate. At Miadzi, in Kiusiu, it is wild on the sides 

 of mountain streams, being a tree of about eighteen inches in diameter. It is also 

 supposed to occur in ithe island of Saghalien, as nuts cast up by the sea were found 

 there by F. Schmidt. 



Sargent ^ says that Juglans Sieboldiana is a common forest tree in Yezo and the 

 mountainous regions of the other islands of Japan. Specimens more than 50 feet 

 high are uncommon. It is a wide-branched tree, resembling the butternut in habit 

 and in the colour of its pale furrowed bark. The walnuts of this species are an 

 important article of food in Japan, as the nuts are exposed for sale in great quantities 

 in the markets of all the northern towns. 



Elwes collected specimens at Asahigawa in central Yezo, and noted that it was 

 always a small tree, 20 to 30 feet in height by a foot in girth. He also saw it near 

 Nikko, but never of any size. It is called Kurunii. The wood, though used to 

 some extent in Japan for gun-stocks and ornamental work, does not take a high 

 place among the valuable timbers of the country. It was not included in the 

 collection of woods exhibited at St. Louis. 



Cultivation 



Juglans Sieboldiana was introduced from Japan into Leyden about the year 

 i860 by Siebold, and was sent from there to Segrez in 1866, under the name of 

 Juglans ailantifolia. At Segrez it passed unscathed through the severe winter of 

 1 879- 1 880, which proved fatal there to the common walnut. 



According to Sargent this species is perfectly hardy in New England, where it 

 ripens its fruit. It is not worth growing there as an ornamental tree ; but it will 

 produce fruit in regions of greater winter cold than the common walnut can support, 

 and may find some place in planting as a fruit tree. 



The largest specimen we know of in these islands is at Belgrove, Oueenstown, 

 Ireland, the residence of W. E. Gumbleton, Esq. It was, in 1903, 24 feet in height 

 by 2 feet 9 inches in girth. There are specimens at Kew about 12 feet high, which 

 were grown from seed received in 1894. There is also a small plant at Gunnersbury 

 House, Middlesex, which has borne fruit.
