A plant with a deep root system which obtains water from the groundwater or the capillary fringe above the water table.



a plant with an extremely deep root system that uses groundwater as its source of moisture. A classical example is the date palm (Phoenix dactylifera), which grows on oases in the Sahara and the Arabian Peninsula. (An ancient Arabic proverb says that the date palm has its head in fire and its feet in water.) Phreatophytes occur in the subtropical eucalyptus forests on the eastern coast of Australia. They serve as indicators of the depth and salinity of the groundwater. For example, the licorice (Glycyrrhiza glabra) is an indicator of fresh water at depths of 5 to 10 m, and Halostachys caspica indicates salt water at depths of 5 to 15 m. Typical phreatophytes include many desert and semidesert plants, for example, camelthorn (Alhagi camelorum), tamarisk (Tamarix), and Achnatherum.

These diatomites, albeit bare of any perennial vegetation cover, exude small springs of highly saline waters and therefore play a determinant role in the distribution of the neighbouring vegetation almost entirely made of halophytes and phreatophytes. The outcrops of the Pre-Cordillera rocks, contrary to the Front Cordillera, are almost totally of a sedimentary nature (with, however, some lightly metamorphized elements of various shales and schists) and they may be of various ages, Paleozoic (Cambrian, Ordovician, Gothlandian, Permian), Mesozoic (Triasic, Liasic and Cretaceaous) and Cenozoic (Miocene and Pliocene) in both continental and marine series.

The marked seasonal phenology, independent of current soil moisture, would be expected of a deep-rooted phreatophyte, but as indicated previously, Prosopis in the Jornada Basin is unlikely to have access to the water table, and small shrubs exhibit the same phenological patterns as do large shrubs.
