Latin Name:  Juglans major
Common Name:  Arizona walnut
Family:  Juglandaceae
Author:  (Torr.)Heller.

Known Hazards:  None known

Mature Height:  15   Mature Width:

Habitat:  Dry rocky ravines and stream beds, 700 - 2300 metres[229].

General Uses: This species is sometimes used as a rootstock[183]. A golden brown dye can be obtained from the seed husks[257]. A light brown dye is obtained from the young twigs[257]. Plants produce chemicals which can inhibit the growth of other plants. These chemicals are dissolved out of the leaves when it rains and are washed down to the ground below, reducing the growth of plants under the tree[18, 20, 159]. The roots of many members of this genus produce substances that are toxic to many plant species, especially apples (Malus species), members of the Ericaceae, Potentilla spp and the white pines (certain Pinus spp.)[200]. Wood - this very attractive wood rivals that of J. nigra, the black walnut, in quality[229]. However, the limited range and smaller size of the tree have restricted its use[229].
