Juglans major (literally, the larger walnut) is a walnut tree which grows to 50 ft tall with a DBH of up to 2 ft at elevations of 1000—7000 ft in Texas, Oklahoma, New Mexico, Arizona, and Utah[1]. Common names include Arizona Walnut and Nogal. In moister areas, the tree features a single, stout trunk; there are usually several slender trunks in drier situations.[2] The 8—14 in long pinnately compound leaves bear 9—15 lanceolate leaflets, 3/8—11/4 in wide by 2—4 in long. The small nut has a thick shell with deep grooves enclosing an oily, edible seed.
Where the range of J. major overlaps that of J. microcarpa, the two interbreed, producing many intermediate forms[3][4].
