the mountains. The wood, according to this author, is light, with Httle difference 

 between the sapwood and heartwood, and when well seasoned does not warp or split, 

 and on this account it is much esteemed for making gun-stocks. Sargent ' did not find 

 this tree in Japan, and says that its peculiar nuts are considered by Japanese botanists 

 to be merely extreme varieties of Juglans Sieboldiana. However, the species is 

 kept up as distinct by Matsumura,^ and cultivated specimens at Kew of the two species 

 can be readily distinguished. 



Rehder states in 1 903 that a tree in the Arnold Arboretum raised from seed of 

 Xxn^ Juglans cordiformis fruited some years ago. The fruits, however, did not show 

 the characteristic form of this species, and he doubted whether the tree in question 

 was true cordiformis, or only a variety of Sieboldiana with aberrant fruit. 



Nuts were obtained in 1862 by Albrecht,' physician to the Russian Consulate at 

 Hakodate, which were sown in the Botanic Garden at St. Petersburg, and produced 

 healthy plants, which were about four feet high, in 1872. Maximowicz also found 

 the nuts in the market at Yokohama. Sargent, who found them offered for sale by 

 the Nurserymen's Association of Yokohama, was informed that they were collected 

 on the slopes of Fujisan. 



The tree has been recently sent out by Continental nurserymen, and is hardy in 

 this country. A specimen at Kew, which was raised in 1899 from seed procured 

 from Harvard, is now about twenty feet high. The male catkins, which are pro- 

 duced freely and expand in May, give the tree a striking appearance, but the fruit 

 has not yet matured. (A. H.)
