Remarques

lyg05 : The Teucrio pseudochamaepityos-Brachypodion retusi Br.-Bl. ex Rivas-Mart. 2011 (see Rivas-Martínez et al. 2011: 286) is an invalid name because the type of the name was invalidly published. Indeed, the new name ‘Irido chamaeirido-Brachypodietum retusi (Br.-Bl. in Br.-Bl., Roussine & Nègre 1952) Rivas-Mart. 2011’ (Rivas-Martínez et al. 2011: 287) should have been published simply as a change of rank. Rivas-Martínez et al. (l.c.) attempted description (‘ass. nov.’) of the latter unit however, they assigned the synoptic relevé for the subassociation ‘crucianelletosum’ as the ‘type’ of the association. Hence the typification was performed invalidly since only a relevé can serve a type in this context. Because there is apparently no validly published name for the ‘Thero-Brachypodion Br.-Bl. 1925’, here we propose validation of the Phlomidi lychnitis-Brachypodion retusi Mateo 1983 nom. inval. (Mateo 1983) and select the Phlomido lychnitis-Brachypodietum retusi Br.-Bl. 1925 (Braun-Blanquet 1925: 304-320) as the holotypus (hoc loco) of the alliance. The diagnostic taxa of this alliance are: Acis valentina, Allium chamaemoly, A. moschatum, Arenaria valentina, Asphodelus ramosus, Astragalus verrucosus, Biarum dispar, Brachypodium retusum, Carlina corymbosa, Charybdis maritima, C. numidica, C. undulata, Dactylis hispanica, Dorycnium pentaphyllum, Eryngium dilatatum, Helictochloa bromoides, Iris lutescens, Ophrys bombyliflora, O. lutea subsp. galilaea, O. lutea subsp. lutea, O. tenthredinifera, Pancratium illyricum, Phlomis lychnitis, Reichardia picroides, Stipa offneri, S. pauneroana, Teucrium pseudochamaepitys and Trisetum flavescens subsp. splendens.
