The Joshua tree is a xerophyte (plant adapted to drought) with so-called xeromorph characteristics. The leaves are leathery and covered with a wax layer to protect the plant from desiccation. The parenchyma cells of the leaf are enlarged and function to store water, a feature that is typical for succulents.
