“…During the last decades (>1950), other countries also act as remarkable gateways, such as Spain and Portugal for taxa alien to Europe. However, this should be related to recent findings in the Macaronesia area due to an intensified monitoring effort (e.g., Silva, Ojeda Land & Rodrıguez Luengo, 2008;Verloove et al, 2017a;Verloove et al, 2017b) and to several ''acclimatisation gardens'' (e.g., the Acclimatisation Gardens of La Orotava in the Canary Islands). Similarly, Denmark and Norway are reported as important gateways for alien taxa in Europe after 1950, which could also be the result of increased sampling effort and availability of information (e.g., via the NOBANIS database).…”

The Convention on Biological Diversity (CBD) pathways classification framework used in the implementation of the European Union’s (EU) Regulation 1143/2014 on invasive alien species (IAS Regulation) has recently been adopted by the European Alien Species Information Network (EASIN), the official information system supporting the implementation of the IAS Regulation. In the current paper, the result of an alignment of the primary introduction pathways of all alien plants in Europe included in the EASIN catalogue is presented, based on the CBD framework. In total, 6,250 alien plant taxa (marine plants excluded), both alien to Europe (native range outside Europe) and alien in Europe (native range partially in Europe) are reported. Altogether 5,175 plant taxa had their primary introduction pathway aligned based on the CBD framework, while for the rest the pathway remains unknown. In addition, the taxonomy, year and country of its first record in the wild are provided for each taxon. Our analyses reveal that the main primary introduction pathways of alien plants into Europe are linked to accidental escapes from ornamental and horticultural activities. Northwestern European countries seem to act as the main gateway areas of alien plants into Europe. Recent first observations of new alien taxa growing spontaneously exhibit a contemporary accelerating trend for plants alien to Europe, particularly linked to ornamental and horticultural activities. On the other hand, the number of new plants alien in Europe seems to have stabilized over the last few decades. The present work can assist in the prioritization of introduction pathways control, with the target of slowing down the rate of alien plants introductions into Europe, following also the requirements of the IAS Regulation.

“…Outside its native area it is planted as an ornamental, although perhaps not widely so. It is mentioned as naturalised only from the Canary Islands (see e.g., Verloove & Guiggi, 2013;Verloove et al, 2017;Korotkova & Raab-Straube, 2017+). The species is here reported for the first time in the flora of Tunisia and the Maghreb, second report in the flora of North Africa and for the third time for the flora of the whole Mediterranean area (Laguna Lumbreras et al, 2015;Korotkova & Raab-Straube, 2017+;Verloove & Guiggi, 2019;Aymerich & Sáez, 2019;APD, 2020).…”

Botanical surveys undertaken in Central and Northern Tunisia (North Africa), mostly between 2015 and 2020, have revealed three new allochthonous cacti. The reported taxa belong to the genus Cylindropuntia (Cactaceae, subfamily Opuntioideae, tribe Cylindropuntieae). C. leptocaulis, C. prolifera and C. spinosior are here reported for the first time from North Africa. Updated nomenclature, descriptions, general and national distributions are pointed out for each species. An analytical key and field photographs are also provided.
