A xerophyte (from Greek ξηρός xeros 'dry' + φυτόν phuton 'plant') is a species of plant that has adaptations to survive in an environment with little liquid water. Examples of xerophytes include cacti, pineapple and some gymnosperm plants. The morphology and physiology of xerophytes are adapted to conserve water during dry periods.

Life forms: (1) Phanerophyte, (2; 3) Chamaephyte, (4) Hemicryptophyte, (5; 6) Geophyte, (7) Helophyte, (8; 9) Hydrophyte. Therophyte and epiphyte are not shown. The Raunkiær system is a system for categorizing plants using life-form categories, devised by Danish botanist Christen C. Raunkiær and later extended by various authors.
Euphorbia is a very large and diverse genus of flowering plants, commonly called spurge, in the family Euphorbiaceae. Euphorbias range from tiny annual plants to large and long-lived trees. [2] with perhaps the tallest being Euphorbia ampliphylla at 30 m (98 ft) or more. [3][4] The genus has roughly 2,000 members, [5][6] making it one of the ...
Deserts and xeric shrublands are a biome defined by the World Wide Fund for Nature. [1] Deserts and xeric (Ancient Greek ξηρός xērós 'dry') shrublands form the largest terrestrial biome, covering 19% of Earth 's land surface area. [2] Ecoregions in this habitat type vary greatly in the amount of annual rainfall they receive, usually less ...
