Abstract

We describe a new subassociation of mesohygrophilous hay meadow for the Mediterranean region of Catalonia (NE Iberian Peninsula): Geranio dissecti-Festucetum arundinaceae (O. Bolòs 1959) Mercadal 2019 subass. ranunculetosum sardoi Mercadal nov. (all. Oenantho- Gaudinion, ord. Trifolio-Hordeetalia). This community is floristically characterized by Poa trivialis, Rumex crispus, Ranunculus sardous, Elymus repens, Carex riparia, Alopecurus myosuroides and Lolium multiflorum. The dominant species are Poa trivialis, Trifolium squamosum and Pontentilla reptans. Syntaxonomically, this community represents a transitional form between the hay meadows of the Oenantho-Gaudinion and the hygrophilous grasslands of the Potentillion anserinae alliance (ord. Potentillo-Polygonetalia).
