Juglans mandshurica Maxim.

Modern name

Juglans mandshurica Maxim.

A tree 50 to 70 ft high; young shoots very stout, and like the common stalk of the leaf, clothed with brown, glandular hairs. Leaves 112 to 2 ft (in vigorous young trees 3 ft) long, composed of eleven to nineteen leaflets, which are oblong, taper-pointed, finely toothed, obliquely rounded or slightly heart-shaped at the base, 3 to 7 in. long, 114 to 212 in. wide; when young, both surfaces are furnished, the lower one especially, with starry tufts of down, much of which afterwards falls away from the upper side. Male catkins 4 to 10 in. long, slender, pendulous. Fruits clustered several on a stalk, roundish ovoid, 134 in. long, covered with sticky down; nut deeply pitted and grooved, 112 in. long, abruptly pointed at the top.

Native of the Russian Far East, especially in the region of the Amur and Ussuri rivers, and of N. China; first introduced by Maximowicz to the St Petersburg Botanic Garden. As a young tree it is, like J. ailantifolia, remarkably striking in the size of its leaves. It is closely allied to that species but does not succeed so well; botanically, the chief difference is in the form of the nuts, and the leaves of J. mandshurica are distinctly more slender-pointed.
