Juglans major is frequently seen as a tall shrub, but with age and enough water, it can become quite a large
tree. The leaves are pinnately compound and the leaflets are serrate. The pith is chambered and best seen by slicing a young branch tangentially with a knife (carefully!) Juglans major probably intergrades with
Juglans microcarpa from elsewhere in the state, and individual plants may have characteristics of both. The fruit (technically a drupe)
is initially covered with a thick green husk, which eventually peels away revealing the stone which contains a single two lobed seed.
In winter, the twigs bear heart-shaped leaf scars containing three bundle scars.
Juglans major is very commonly found in dry washes and canyons.
