Deeply connected with forest serial dynamics, and present in almost semi-natural landscapes of Iberian Peninsula, Dactylis hispanica subsp. lusitanica perennial grasslands antalis a major issue on biogeographical analysis, once it lacks on syntaxonomical solutions for its affiliation and respective positioning on serial dynamics of distinct territories, which edaphoclimatic envelopes suggest different floristic assemblages. Mainly part of Agrostion castellanae-Stipion giganteae alliance, the Lusitan-Extremadurean grasslands were studied, with the objective of updating that biogeographic Province, and several phytosociological relevés were made, allowing the syntaxonomical update as well to resolve the serial-dynamics arrangement where this peculiar grasslands makes part of. At last this communities belong to priority 6220 [*Pseudo-stepe with grasses and annuals (Thero-Brachypodietea)], habitat that interests as well for conservational matters, due to its peculiar flora.
