Fruit.—October. Spherical, 3-6 inches in circumference: husks rather thin, firm, green turning to brown, separating completely into 4 sections: nut variable in size, subglobose, white, usually 4-angled: kernel large, sweet, edible.

Horticultural Value.—Hardy throughout New England; prefers light, well-drained, loamy soil; when well established makes a moderately rapid growth; difficult to transplant, rarely offered in nurseries; collected plants seldom survive; a fine tree for landscape gardening, but its nuts are apt to make trouble in public grounds. Propagated from a seed. A thin-shelled variety is in cultivation.
