Estado actual de la clase Poetea bulbosae en la Península Ibérica

Abstract

The Poa bulbosa communities present in the Iberian Peninsula are studied. With the aid of tables of associations provided by other authors and unpublished data, some statistical analyses (cluster analysis, Euclidean distance and PCA-analysis) were car ried out and a synthetic table was made to characterize the distinctive groups of taxa of each association. In both cases there are some rearrangements, which, together with the floristic and ecological study, lead us to propose the following novelties: Poetum ligu latae-bulbosae ass. nova hoc loco with a variant of Hieracium baeticum in the basophi lous communities, Festuco amplae-Poetum bulbosae plantaginetosum radica tae comb. nova for the silicicolous grasslands, and Plantaginenion serrariae stat. nov. (Tri folio sub te r ranei -Pe riballion ) for neutro-basophilous, vertic and siliceous soils.
