Jubaea spectabilis, Humboldt. 



The tall and stout Coquito-Palm of Chili. Well adapted for 

 our extra-tropic latitudes. A kind of treacle is obtained 

 from the sap of this Palm. The small kernels are edible. 



Juglans cinerea, Linne.* 



The Butternut-tree of North America. About 50 feet high; 

 stem-diameter 4 feet. Likes rocky places in rich forests. 

 Wood lighter than that of the Black Walnut, durable and 

 free from attacks of insects. It is particularly sought for 

 panels of coaches, corn-shovels, wood dishes and similar 

 implements, as it is not liable to split, nor heavy. The 

 leaves, bark and husk are of medicinal importance, and so 

 are those of other species. 



Juglans cordiformis, Maximowicz. 



Japan. This species approaches in many respects J. 



Sieboldiana. 

 Juglans Mandscliurica, Maximowicz. 



Corea and Mandschurica. This Walnut is allied to J. cinerea 



of North America. 



Juglans nigra, Linne."^ 



Black Walnut-tree. Attains a height of 70 feet; trunk 4 

 feet in diameter; found in rich forest-land in North America. 

 Wood purplish-l3rown, turning dark with age, strong, tough, 

 not liable to warp or to split ; not attacked by insects. Wood 

 stored for many years is the best for gun-stocks. For the 

 sake of its compactness, durability and its susceptibility to 

 high polish, it is much sought for elegant furniture, stair- 

 rails and other select purposes. Seed more oily than the 

 European walnut. 



Juglans regia, Linne.* 



The ordinary Walnut-tree of Europe, but of Central Asiatic 

 origin; it attains a height of fully 80 feet, and lives many 

 centuries. Wood light and tough, much sought for gun- 

 stocks, furniture and other things. The shells of the nut 

 yield black pigment. Trees of choice quality of wood have 

 been sold for £600, the wood being the most valuable of 

 Middle Europe. In some departments of France a rather 

 large quantity of oil is pressed from the nuts, which, besides 

 serving as an article of diet, is used for the prej^aration of 

 fine colours. To obtain first-class fruit, the trees are grafted 

 in France (Michaux). An almost huskless variety occurs in 

 the north of China. Can be grown in cold localities, as it lives
