Anotations

Scope note:

Wood of the species Juglans regia, native to the Himalayas, Iran, Lebanon, Asia Minor, and Greece. It was introduced into Britain in the mid-15th century. It has a uniform, deep brown color with a medium texture and a close, straight grain. It varies considerably in color the sapwood being pale straw with grayish-brown heartwood with infiltrations of coloring producing a darker-colored streaky appearance. It is strong but easy to work and polishes to a high gloss. It is used for furniture, veneers, cabinets, paneling, gun stocks. Its burls are especially prized in the furniture trade. For the darker wood from the species Junglans nigra found in the eastern United States, use "black walnut."
