    • n xerophyte In phytogeography, a plant adapted to live under conditions of small available moisture. The name was first applied to plants inhabiting arid lands; but it now includes also the vegetation of salt marshes (see halophyte), of arid bogs and moors, and of cold regions, since in these situations, though the physical water (that is, the actual moisture) is copious, the physiological water (that which the plant is capable of appropriating) is scanty. The latter classes of plants possess adaptive modifications similar to those of dry-ground plants. Xerophytic adaptations are divided by F. E. Clements into those having to do with the increase in size and effectiveness of the root-system, by which absorption is increased; those developed in root, stem, and leaf for the storage of water; those in which the surface of the plant is reduced; and those arising in or near the epiderm, in consequence of which transpiration is decreased. Compare hydrophyte and mesophyte. See also xerophilous.
