Contribution to knowledge of Apennine colline-submontane garigues on terrigenous rock types

This study provides new data and an in-depth syntaxonomic analysis of Apennine garigues in the Cisto cretici-Micromerietea julianae class, relative to terrigenous substrates in temperate bioclimates. In this context, it is proposed to elevate the suballiance Astragalenion monspessulani Biondi, Allegrezza & Zuccarello 2005 to the rank of alliance, with the name of Astragalion monspessulani, and to introduce the new Astragaletalia monspessulani order. The study also describes a number of new associations and subassociations belonging to the Astragalion monspessulani and Cisto cretici-Ericion manipuliflorae alliances.
