Resumo: The mesophilous woods dominated by Quercus faginea subsp. faginea or Acer monspessulanum thriving on neutral to alkaline deep clayish soils have been collected under the alliance Aceri granatensis-Quercion fagineae (Rivas Goday, Rigual & Rivas-Martínez in Rivas Goday, Borja, Esteve, Galiano, Rigual & Rivas-Martínez 1960) Rivas-Martínez 1987. Punctually, woods dominated by Q. faginea subsp. alpestris, Corylus avellana or Acer granatensis have also been ascribed to this alliance. In the Iberian Peninsula, these mesophilous woods are mainly found within the Western Mediterranean region, mainly in the eastern half of the Iberian Peninsula and occasionally in the Majorcan northern mountains, generally in mountainous areas under meso to supramediterranean, sub-humid to humid, euoceanic to semicontinental bioclimates (Rivas-Martínez et al. 2002). This alliance belongs to the Quercetalia pubescentis order from the Querco-Fagetea class, and was not represented in Portugal until the actual moment. We present two new associations, one dominated by Quercus faginea subsp. faginea and a second one dominated by Acer monspessulanum for the Portuguese territory. We analysed 188 Iberian vegetation relevés ascribed to the Aceri granatensis-Quercion fagineae alliance using a cluster analysis (both agglomerative and k-means clustering). The results were generally consistent with the phytosociological unit, but minor changes are proposed. A subsequent analysis of the indicator value (of Dufrêne & Legendre) of species is presented, highlighting the species with higher indicator values resulting statistically significant on the permutation test.
