Mr. W. C. L. Drew has a good word for this tree, in the Rural New Yorker he says :
" Trees of this kind were found growing only in one locality in the foot-hills of the Sierra Nevada, but from there they have been introduced into nearly all sections of the State. The tree is a slow grower, and has to be from eight to ten years old before producing fruit, but after it has once borne fruit, it will never fail to set a yearly crop. The tree grows from twenty to forty feet high, is strong, hardy, and well branched. The foliage is of a rich, dark green, and quite different from that of the English or Eastern Walnut; it is unequally pinnate, compound, from ten to fourteen inches long, the leaflets, of which there are fifteen to thirty-five on a leaf, are lanceolate in shape, about three-quarters to one inch across at their broadest portion, and from two to three and a-half inches in length; the foliage is very densely set on the tree, much more so than in the English Walnut".
