Ephemerals are classified as drought escaping plants because they avoid the drought period entirely by existing as dormant seeds.

Acacia arabica is xerophyte because it is seen in desert places.

Xerophytes minimize water loss by reducing the number of stomata or having them sunken. A larger number of stomata would increase transpiration, which is detrimental to a plant in a dry habitat.

Calotropis is a non-succulent xerophyte that features thick, leathery leaves covered in a white, waxy, or hairy coating to reduce water loss and reflect sunlight.

Xerophytes are made up of thick cuticles and contains parenchymal tissues. It does not contain Aerenchyma.

In many xerophytes, leaves are reduced to spines to prevent water loss. Consequently, the stem becomes green and photosynthetic (cladode or phylloclade) to perform the function of leaves.

Halophytes grow in saline environments where water uptake is difficult due to high salt concentrations, leading to physiological drought. Thus, they often develop xerophytic adaptations.

Agave is a well-known succulent xerophyte that stores water in its thick, fleshy leaves.

Capparis is a genus of shrubs that are well-adapted to dry, arid environments, making them true xerophytes.
