Resumo(s)
The rocky habitats of southern Portugal are ecosystems with extreme xericity conditions, associated with special abiotic strains. In these unstable ecological conditions, a considerable diversity of plant communities occurs. The objective of this study, carried out in the Algarve and Monchique, and the Mariánica Range biogeographical sectors, is to compare chasmo-chomophytic communities of the southwestern Iberian Peninsula, using a phytosociological approach (Braun–Blanquet methodology) and numerical analysis (hierarchical cluster analysis). From these results, two new communities were identified, <i>Sanguisorbo rupicolae-Dianthetum crassipedis</i> and <i>Antirrhinetum onubensis</i>, as a result of floristic and biogeographical differences from other associations already described within the alliances <i>Rumici indurati-Dianthion lusitani</i> and <i>Calendulo lusitanicae-Antirrhinion linkiani</i>, both included in the <i>Phagnalo saxatilis-Rumicetea indurate</i> class.
