Walnut

Walnuts (genus Juglans) are plants in the family Juglandaceae. They are deciduous trees, 10 - 40 metres tall, with pinnate leaves 200 - 900 millimetres long, with 5 - 25 leaflets; the shoots have chambered pith, a character shared with the wingnuts (Pterocarya) but not the hickories (Carya) in the same family.
