A magnificent tree, Juglans major can be found in the Gilbert Carter Woodland.
Juglans major, or the Arizona walnut, is one of approximately 15 species of deciduous woodland trees which occur in south eastern Europe, Asia, North America and northern South America. In the wild this species has a natural distribution from Mexico to the southwestern United States, where it grows along permanent and ephemeral waterways, and also in valleys and canyon walls. It is a highly attractive specimen tree with deeply fissured bark and a wide, spreading crown. The leaves are formed of up to twenty narrow, toothed leaflets, which take on golden tones in autumn, and it produces globose fruits covered with a thin husk. It is often confused with the Texas walnut (J. microcarpa syn. J. eleaopyren). This is a splendid tree, and Bean observed in his ‘Trees and Shrubs Hardy in the British Isles’ that ‘a very handsome specimen grows in the University Botanic Garden, Cambridge.’
