The precise distinctions between xerophytes
and sclerophylls are not conspicuous, presumably due to many similar environmental attributes between semi-arid coastal sclerophyllous chaparral and arid continental Mojave Desert shrublands.

Dominant vegetation types are shrubland steppes of xerophytes
, psammophytes or halophytes, as well as marginal Prosopis woodlands (Cabrera, 1971).
Salinity is one of most threatening abiotic stresses to plants as saline area is three times greater than the agricultural land throughout the world, however many plants naturally adapt tolerance toward salt stress such as Halophytes, and xerophytes
etc (Boscaiu et al.
The sparse vegetation of this area consists of xerophytes
that are modified to extreme summer temperatures and moisture fluctuations with wide diversity of edaphic conditions.
A promising solution could be to grow certain species of edible xerophytes
and/or halophytes, which would be cultivated under marginal conditions, such as salinity, by using water and land classified as inadequate for traditional fodder crops.
A number of torus-bearing angiosperm species are xerophytes
, and the presence of a torusbearing pit membrane can be viewed as another mechanism for control of water resources under arid conditions.
Echis carinatus sochureki, on the other hand, occurs on rocky, sandy, and alluvial soils with vegetation varying from sparse xerophytes
to moderately dense grass and scrub.
salicina community (Molinion) in including several xerophytes
and mesoxerophytes, e.
normally have a number of adaptations to hydric stress (TURNER, 1986), mesophytes can also adapt in order to survive in environments where seasonal deficits occur (CALBO; MORAES, 2000).
The pollen production of local taxa is very low, among which Betula nana, Salix, Selaginella selaginoides, Dryas octopetala and steppe xerophytes
Eurotia ceratoides, Ephedra and halophilous taxa Kochia prostrata, Salsola kali and Salicornia herbaceae have been identified (Pirrus 1971).
Opuntia cacti are wild xerophytes
that are used in many regions of the world, primarily for food, fodder, and medicine; they generally grow in dry sunny areas, where there are few other deep-rooted plants.
Aloes are xerophytes
in the Aloeaceae in the Liliales that approximately 400 species have been described in the genus Aloe .
Osmolyte accumulation in xerophytes
as a response to environmental stress.
Vegetation of this wetland consists of; hydrophytes, halophyte, xerophytes
