Sedetum lagascae ass. nova hoc loco (9.4.9)

(Cicendion, Isoetetalia, Isoeto-Nanojuncetea)

Typus associatio: Table 88, rel. 4 [Avila: San Martín de la Vega del Alberche, Barbabúo creek. 30TUK1679. 1540 m, 1 m2].

Characteristic species: Sedum lagascae (Sedum maireanum).

Diagnosis: Association dominated by the succulent-leaved therophyte Sedum lagascae and several dwarf annual rushes (Juncus bufonius, J. tenageia, J. capitatus), growing on shallow mineral soils developed on siliceous rocks and submitted to short spring episodes of hydromorphy. They bloom in late spring-early summer and are mainly distributed in the meso and supramediterranean belts (up to 1800 m) of the Mediterranean West Iberian Province.

Remarks: Brullo & Minissale in Itinera Geobot. 11: 282. 1998 proposed the new association Junco bufonii-Sedetum lagascae based in the rel. 10, tb. 9 published by Sánchez-Mata (1989: 76) as "Comunidad de Juncus bufonius y Sedum lagascae". As the Italian authors do not give any comment in the text out of the number of the table, it seems possible to consider the association name as invalidly published (art. 2b), if contrarily we accept it as valid name the citation should be Junco bufonii-Sedetum lagascae Sánchez-Mata ex Brullo & Minissale 1998.

Characteristic species (territorials): Arthrocnemum macrostachyum, Elytrigia curvifolia, Inula crithmoides, Limonium ruizii, Sarcocornia alpini, Suaeda braun-blanquetii, Tamarix canariensis.

Diagnosis: Middle basin of the Ebro river halo-hydromorphic microforests in which Tamarix canariensis is dominant. These salt marsh Tamarix communities, from pond borders, endorreic depressions, intermittent water courses, etc., represent the head of the series or potential natural vegetation on saline hydromorphic soils, in the mesomediterranean xeric or pluviseasonal dry belts of the Bardenan-Monegrensean Sector, although its presence could also be interpreted in the Manchean Sector. A great number of halophilous plants grow in its under-storey or among the Tamarix and belong to the classis Sarcocornietea fruticosae such as: Arthrocnemum macrostachyum, Inula crithmoides, Limonium ruizii, Sarcocornia alpini, Suaeda braun-blanquetii, etc. These habitats, that are given priority by the European Union Directives, are greatly threatened because of the drainage and the agricultural development of irrigated land.
