[ZG] EuropeMots-clés : plante invasive Résumé : "Arundo donax L. (Poaceae) isconsidered to be one of the worst invasive plants in the world, and here, we present a synthesis of ail aspects of its biology, ecology and management that are relevant to understanding its invasive behaviour. This report presents information on the taxonomy, morphology, distribution, history of introduction and spread, ecology, responses to abiotic and biotic factors, biology, negative impacts, management and uses within the framework of a series of Botany Letters on Monographs on invasive plants in Europe. Arundo donax (giant reed) originated in subtropical Asia and is invasive in other warm regions worldwide, especially in degraded riparian areas. Introduced for use in agriculture, erosion control and construction in the Mediterranean European region since ancient times, it has become naturalized in several freshwater habitats and in disturbed areas. In its introduced range, A. donax shows strong genetic uniformity and no seed production. This situation is reversed in Asia, where this taxon is fertile and orphologically and genetically polymorphie. This perennial grass combines rhizomatous clonai growth with a tolerance to a wide variety of ecological conditions, such as high salinity levels and long droughts. This tall reed can increase the risk of fire, alter the natural drainage of channels and invade very sensitive habitats, posing a serious threat to riparian habitats and freshwater ecosystems. Effective methods to control A. donax are tarps on a c1eared giant reed field to completely cover the affected zone, rhizome removal using a modified backhoe bucket adapted to separate soir from the rhizomes, and herbicide application on leaves. The combined technique of herbicide treatment plus stemcutting can be included in management programmes, and this technique needs to be monitored over the long term to assess its success and to ensure native species colonization and ecosystem recovery. Regarding biological control, A. donax is host to different insect species that have been released to control it in parts of its non-native range (North America) with some success. However, these different methods of control should continue to be studied, evaluating the risks posed to the environment and the control lever achieved. In this context, scientific, political and administrative efforts as weil as environmental education are effective assets to address the management of this invasive species."

Within section Dalycum, Melica ciliata sensu lato forms a taxonomic complex of several species and subspecies with clinal morphological variation causing conflicting identifications. To resolve taxonomic confusion, we employed three complementary approaches, through molecular, morphological and phytoecological analyses. The double‐digest restriction associated DNA markers significantly support the monophyly of three taxa: (i) the Mediterranean M. magnolii, (ii) the Eurasian M. transsilvanica subsp. transsilvanica and (iii) the west‐European M. ciliata subsp. glauca. This differentiation is corroborated by the analysis of 22 morphometric variables. Furthermore, phytoecological analysis of 221 floristic inventories revealed habitat distinctions among these taxa. Our approach of integrative taxonomy argues for a specific distinction for these three taxa, and we include a key to separate these forms. This new molecular data on the section Dalycum, subsection Ciliatae, calls for further phylogenetic analyses including samples of M. ciliata subsp. ciliata and other East‐Mediterranean and South African taxa.
