New records of alien plants in the Canary Islands (ES)
New records and distributions are presented for species and hybrids that are either new to the Canary Islands as a whole or new to the island of Gran Canaria. The authors highlight that although several of the species are only ephemerals at present, almost all of them have the potential to naturalise and become invasive in the future as such behaviour has been observed in areas with similar climatic conditions.
