Xerophytes are plants that are adapted for arid environments. Common xerophytic features include: succulent tissues that store water and organic acids, photosynthetic stems with reduced surface area, waxy cuticles to limit water loss, sharp spines, reflective hairs, and underground tubers. Xerophytism is an example of evolutionary convergence, in which distinctly dissimilar ancestors give rise to similar descendants through selection for a common set of features.
