Abstract: In this paper a survey on the garrigue vegetation dominated by Satureja montana subsp. montana occurring in the Alta Murgia National Park is presented. These communities were compared with those of the Ionian Arc ravines. Syntaxonomic, structural, chorological and ecological analyses were performed in order to achieve a proper classification of this vegetation. A new association is here described, the Rhamno saxatilis-Saturejetum montanae, with two new subassociations, typicum and fumanetosum procumbentis. It is a garrigue vegetation dominated by Satureja montana subsp. montana occurring in the Murgian area, in sites characterized by rocky and stony soils and by a Mediterranean Pluviseasonal oceanic weak semicontinental phytoclimate, with thermotype upper meso-Mediterranean and ombrotype lower subhumid, and is here framed in the Cytiso spinescentis-Saturejion montanae alliance (order Cisto cretici-Ericetalia manipuliflorae, class Cisto cretici-Micromerietea julianae). The results contribute to add a further piece to the knowledge of the natural plant landscape of the territory of the Alta Murgia National Park.

Abstract: Artemisia eriantha Ten., also known as "Apennines genepì", is a valuable aromatic plant with several medicinal properties. Among the several phytoplasma symptoms to which this plant can be subjected, the fasciation is one of the less reported and studied. In natural environments this plant is a characteristic species of the association Artemisietum erianthae Brullo 1984. In this study, the first occurrence of fasciation in Artemisia eriantha is described. This phenomenon was observed during the ex vitro experimental cultivations, located in Assergi and Barisciano (L’Aquila, Italy), settled for the restocking of this endangered species. The fasciation occurred only in Assergi experimental field with a magnitude of 0.12%. Specific PCR analysis did not show the phytoplasma presence. This fist report allows to expand knowledge about fasciation in Apennines genepì.
