The declination of the Quercetea robori-petraeae Braun-Blanq. & Tüxen ex Braun-Blanq., Roussine & Nègre 1952 class is proposed for the new French vegetation prodrome (PVF2). It contains 23 associations, 4 sub-alliances, 8 alliances and 3 orders. This class comes from the spliting of the Querco roboris-Fagetea sylvaticae Braun-Blanq. & Vlieger in Vlieger 1937 “ superclass », which appeared in the first French vegetation prodrome (PVF1, BARDAT et al., 2004). Besides the creation of a separate class, there are very few changes from the first French vegetation prodrome (PVF1, Bardat et al., 2004). This new class corresponds to the PVF1 Quercetalia roboris Tüxen 1931, except that we recognise the order of the Molinio caeruleae- Quercetalia roboris H. Passarge 1968 for the alliance Molinio caeruleae-Quercion roboris Scamoni et H. Passarge 1959 (this alliance was in the Quercetalia roboris in the PVF1). The Quercetalia roboris is increased by two new alliances, a continental one (Agrostio capillaris- Quercion petraeae Scamoni & H.Passarge 1959) and a very oceanic one, the Hymenopyllo tunbrigensis-Quercion roboris Je. Pall. 2000. The PVF1 Hyperico montani-Quercenion robori- petraeae Rameau 1996 nom. inval. is validated here, but as an alliance (Hyperico montani- Quercion petraeae Rameau ex all. nov.). Finally, the Lonicero periclymeni-Betuletalia pubescentis Willner & Mucina in Willner et al. 2016 is added, even if we lack data to propose any association. Key-words Querco roboris-Fagetea sylvaticae Braun-Blanq. & Vlieger in Vlieger 1937, Quercetalia roboris Tüxen 1931, Molinio caeruleae-Quercetalia roboris H. Passarge 1968, beech-oak forest, oak forest, acidophilous deciduous forests.

Une végétation herbacée d’ourlet intraforestier du bassin aquitain est décrite selon la méthode phytosociologique : l’Hyperico androsaemi – Caricetum pendulae, ourlet mésohygrophile, méso-eutrophile, planitiaire à collinéen appartenant à la classe des Galio aparines – Urticetea dioicae. Le tableau de relevés triés ainsi que la caractérisation floristique et la physionomie de cette association végétale sont présentés. Ses propriétés synécologiques, chorologiques, phénologiques et dynamiques sont précisées. Sa classification syntaxinomique est discutée. Mots-clés : dynamique forestière, phytosociologie, Hyperico androsaemi – Caricetum pendulae, Impatienti noli-tangere – Stachyon sylvaticae, Galio aparines – Urticetea dioicae, syntaxinomie

The aim of this study is to provide new syntaxa for the Italian vegetation checklist. For the class Rhamno–Prunetea which includes the class Paliuretea the new alliance Rhamno saxatilis–Paliurion spinae-christi is described, that is included in the order Paliuretalia spinae-christi with a central-western Mediterranean and sub-Mediterranean distribution. Otherwise, the more thermophilous Paliurus spina-christi vegetation is included in the new suballiance named as Oleo sylvestris–Paliurenion spinae-christi within the alliance Oleo–Ceratonion of the class Quercetea ilicis. For the class Trifolio–Geranietea medii, a new alliance named Hyperico calabricae–Asphodelion macrocarpi is proposed here.
