According to UPGMA cluster analysis division and NMDS ordination the relevés were classified into four major groups which gave rise to three sub-associations (Gargano) and a geographically impoverished variant (Alta Murgia). The new association <em>Stipo austroitalicae</em>-<em>Seslerietum juncifoliae</em> ass. <em>nova </em>was proposed. Due to the relict and scattered distribution of <em>Sesleria juncifolia</em> in Apulia region, the variances in species composition amongst the different subassociations are mainly influenced by local factors. The community <em>Stipo-Seslerietum</em> should be included in the south-eastern Italian alliance<em> Hippocrepido-Stipion austroitalicae</em> while at the rank of order it exhibits intermediate coenological features between the Central - South Apennine endemic suborder <em>Festuco-Seslerienalia nitidae</em> and the North-West Balkan order <em>Scorzonero-Chrysopogonetalia</em>.</span></p> ER -
