expand Abstract

The alliance name Poo-Astragalion has been widely used by Iberian phytosociologists for nearly fifty years to indicate a type of sheep pastures thriving on base-rich substrates. This alliance is currently classified in the order Poetalia bulbosae and class Poetea bulbosae. However, the revision of its original diagnosis highlights that this alliance name must be considered as an alternative name to the largely disused name Medicagini-Brachypodion distachyi. In order to stabilize the nomenclature, we propose the conservation of the traditionally used name Poo-Astragalion. On the other hand, the type association of the alliance (Poo-Astragaletum sesamei) turns out to be a superfluous name for another association neglected in the syntaxonomical literature, the Astragalo scorpioidis-Medicaginetum truncatulae. Hence, with the same objective of stabilizing the nomenclature, we propose the designation of a conserved neotype for the Poo-Astragaletum sesamei and the conservation of this name against the earlier heterotypic synonym in case of union of both associations. At the same time, we propose to complete the two names Poo-Astragalion and Poo-Astragaletum sesamei by selecting Poa bulbosa and Astragalus sesameus as the name-giving taxa, and to invert the name Poo-Astragaletum in accordance with its neotype (Astragalo sesamei-Poetum bulbosae).
