Müller et Görs 1958 Calamagrostio-Salicetum cinereae Soó et Zólyomi in Soó 1955 Although in the investigated area we found no Calamagrostis canescens population, and neither the floristic literature has reported this species in the Vargata commune area, considerations related to synchorology have led us to report Salix cinerea coenoses in the association described by Soó and Zólyomi (1955). Most of the clumps of Salix cinerea have a subrecent origin, by their development on sites where, following deforestation of hornbeam oakery, the physiological drainage has ceased and the groundwater has increased. Similarly, such clusters also continue to grow on the meadows belonging to the Molinietalia order, where, due to groundwater raising, the hay exploitation has ceased. The correspondence between habitat type in the classification system used at European level and Romanian level is: R4419 — Tufárisuri sud-est carpatice de zálog (Salix cinerea) cu Calamagrostis canescens (East Carpathian grey willow-carrs with Calamagrostis canescens) Correspondences: NATURA 2000: -EMERALD: 44. Temperate riverine and swamp forests and brush CORINE: 44.921 Grey willow scrub PAL.HAB 1999: 44.9213 Intra-Carpathian grey wilow-carrs EUNIS: F9.213 Intra-Carpathian grey wilow-carrs The composition of the analyzed groups (Table 1) are distinguished by a large number of transgressive species of Molinio-Arrhenatheretea class (Filipendula ulmaria, Sanguisorba officinalis, Lychnis flos-cuculi, etc.), as well as of the Calthion alliance (Caltha palustris ssp. laeta, Myosotis scorpioides). A remarkable number of hygrophilic species is also met (Lysimachia nummularia, Ranunculus repens). The phytocoenoses of this association are predominantly mesophilic (44.74%) and mesohygrofilic (27.63%), micro-mesothermal (55.26%) and euriionic (39.47%) (Fig. 2).
