In Europe it usually occurs in two types of habitats, on lake shores and in greenings, flowerpots and flowerbeds. Few records are known so far from Slovakia, all from garden centers, greenhouses, flowerbeds and flowerpots, but we assume that this species is much more common, but overlooked or misidentified as C. flexuosa or C. hirsuta. In this paper, we review the current knowledge about this inconspicuous neophyte with regards to its origin and distribution in Europe and Slovakia. To the best of our knowledge, the first known occurrence of this species in Europe dates back to 1977, while the oldest known record from Slovakia is from 2002, which is currently the third oldest one from Europe. Particular attention is paid to summarize its cytological and morphological differences from C. flexuosa and C. hirsuta. These three species differ in ploidy levels and genome sizes, thus flow cytometry may be applied for identification of juvenile or phenotypically ambiguous individuals. Morphological differences among the species are presented, and detailed ink drawings and an identification key are provided."

First evidence for the presence of invasive Solidago altissima (Asteraceae) in Europe / Filip Verloove in Willdenowia, vol. 47, n°1 (Année 2017)

Public [article]  inWilldenowia > vol. 47, n°1 (Année 2017) . - pp. 69-75 Titre : First evidence for the presence of invasive Solidago altissima (Asteraceae) in Europe Type de document : texte imprimé Auteurs : Filip Verloove, Auteur ; Ben J. M. Zonneveld, Auteur ; John C. Semple, Auteur Année de publication : 2017 Article en page(s) : pp. 69-75 Langues : Anglais (eng) Catégories : [Espèces (in biblio)] Solidago [Espèces (in biblio)] Solidago altissima [Espèces (in biblio)] Solidago canadensis [ZG] Europe Mots-clés : Compositae  génétique  cytométrie en flux (CMF)  plante invasive Résumé : "The North American invasive species Solidago altissima L. (Asteraceae) is reliably recorded from a single locality in Belgium (Beveren, Waaslandhaven, Verrebroekse Plassen). Nuclear genome size, as measured by flow cytometry, showed this population to be distinct from the closely similar and widespread S. canadensis L. Plants were shown to be hexaploids, with an estimated chromosome number of 2n = 54, while only diploids (2n = 18) of S. canadensis are known from Europe. These findings were further supported by morphological traits. Solidago altissima has repeatedly been claimed from Europe but all these records may be referable to S. canadensis var. canadensis and, more likely, S. canadensis var. hargeri Fernald. To the best of our knowledge, the recently detected population in Belgium represents the first unequivocal record of S. altissima in Europe."
