Abstract

Rocky pastures dominated by Stipa austroitalica in the south-east of Italy wereclassified within an endemic alliance, Hippocrepido glaucae-Stipion austroitalicae, originallyassigned to a Balkan order (Scorzoneretalia villosae). Actually, the distribution area of S.austroitalica extends further westwards and large patches are found on the south-east side ofthe Pollino Massif. This study aims to describe and characterise the plant communitiesdominated by S. austroitalica in this area and analyse their floristic and chorologicalrelationships with other associations of Hippocrepido-Stipion. Moreover, their syntaxonomyis discussed in the context of the Italian and south European dry grasslands biogeography. Thegrasslands were studied on the basis of 19 phytosociological relevés. A larger data set,including 185 relevés with S. austroitalica, was used to visualise the relationships among theassociations through nonmetric multi-dimensional scaling ordination. The results allowed thedescription of a new association, Bupleuro gussonei-Stipetum austroitalicae, classified withinHippocrepido-Stipion. As a consequence, the alliance synrange was extended up to thePollino Massif. Hippocrepido-Stipion, together with Cytiso spinescentis-Bromion erecti, wasarranged in Euphorbietalia myrsinitidis, an endemic order of the Italian peninsula. Theproposed scheme upgrades the syntaxonomy and nomenclature of the dry grasslandsvegetation of central and southern Italy.
