A systematic review based initially on 120 phytosociological relevés and using numerical analyses with classification (Euclidean distance and UPGMA and MISSQ) and ordination (principal component analysis - PCA) was carried out. Four groups corresponding to the following associations were recognized: Junco pygmaei-Isoetetum velati, Peplido hispidulae-Isoetetum delilei, Junco capitati-Isoetetum histricis, Isoetetum durieui. The study supports previous assumptions that, on the local scale within the Iberian Peninsula, temporary-pond plant-communities show greater diversity in western territories thus following the same pattern that occurs on the regional scale of the Mediterranean basin. © 2005 Gebrüder Borntraeger.10aIsoetid vegetation10aNumerical ordination10aVernal pools10aWestern Mediterranean1 aMolina, J.A.  uhttp://www.scopus.com/inward/record.url?eid=2-s2.0-31344444941&partnerID=40&md5=1d0cd9578246354cb891004f5102f08c
