01Description
In moister areas, the tree features a single, stout trunk; there are usually several slender trunks in drier situations. The 8-14 in (20-36 cm) long pinnately compound leaves bear 9-15 lanceolate leaflets, 19-32 mm (0.75-1.25 in) wide by 51-102 mm (2-4 in) long. The small nut has a thick shell with deep grooves enclosing an oily, edible seed.
J. major grows primarily in canyons or riparian areas, near springs, and other areas with shallow groundwater. Where the range of J. major overlaps that of J. microcarpa, the two interbreed, producing many intermediate forms.
