Xerophytes

BIOGEOGRAPHERS AND ecologists usually classify plants according to their water needs. Since the global distribution of water varies from dry to wet, plants also vary in their adaptation to the availability of water. Xerophytes are plants of the arid regions. The Greek prefix xero- means dry in contrast to hygro- (wet) and meso- (intermediate). Xerophytes as a class of plants are those that have adapted to dry environments by some mechanism to prevent water loss or to store water in their leaves.
