Phreatophytes are plants that are supplied with surface water and often have their roots constantly in touch with moisture. A phreatophyte is one that absorbs its water from a constant source on the ground.Phreatophytes are plants that depend on ground water within reach of their roots for their water supply. More than 70 species of plants have been classified as phreatophytes (Kobinson, 1958, p. 1). The consumptive use of water differs greatly among species, but, in general, phreatophytes use more water than otherPhreatophytes. Typically, the vegetation is a mixed assemblage of obligate and facultative phreatophytes—deeply rooted plants that obtain water directly from the stream or from groundwater in the alluvial aquifer.

Smith et al. 1998). As drought- tolerant phreatophytes, Tamarix can utilize water sources other than groundwater, such as water in unsaturated alluvial soils (Busch et al., 1992). Drought tolerance can play a role in Tamarix invasions (Cleverly et al. 1997), and allow Tamarix to recover quickly after drought (Devitt et al. 1997a).Abstract. Phreatophytes are deep-rooted trees and shrubs that obtain a dependable water supply from the “phreatic surface” (Meinzer 1927), i.e., from the saturated water table, and thus maintain water status that is largely independent of soil water derived from incident precipitation.Literary usage of Phreatophytes.
