Phytosociology of halophilic species from the genus "Tamarix L. (Tamaricaceae)" on the island of Gran Canaria

[EN] Forested Tamarix L. species found in the Canary Islands as in the Western Mediterranean Basin and the Saharo-Arabian area are included in the class Nerio-Tamaricetea within the order Tamaricetalia africanae order recognized by the Canaries that does not include Tamarix africana Poir., and the halophilic and halotolerant their communities are included in the alliance Tamaricion boveano-canariensis with the new partnership Atriplici ifniensis Tamaricetum canariensis endemic to the Canary Islands, which is also poor in the characteristic species of the class and to be defined almost exclusively for Tenerife requires a broader review.
