Abstract

Recent fieldwork by the author in Tenerife, mostly between 2014 and 2019, yielded new records of alien vascular plants.Fifteen taxa (Acacia decurrens,A. mearnsii,Caesalpinia pulcherrima,Ensete ventricosum, Eucalyptus camaldulensis subsp. arida,E. cladocalyx,Euryops chrysanthemoides,Ficus elastica,Lippia alba,Pavonia sepioides,Pittosporum tobira, Populus × canadensis,Pyrostegia venusta,Ruellia dipteracanthusandWigandia kunthii) are reported for the first time from the Canary Islands. All were initially introduced on purpose, mostly as ornamentals, and recently started to escape from cultivation. Most of them are ephemerals or only locally established, but nearly all have the potential to naturalise in the future. Thirteen additional species are reported for the first time from Tenerife:Atriplex nummularia,Bellis perennis,Chenopodium probstii,Coccoloba uvifera,Commelina benghalensis,Cuphea hyssopifolia,Eragrostis virescens,Lemna minuta,Malvastrum corchorifolium,Plerandra elegantissima,Psidium guajava,Thunbergia alataandUrochloa subquadripara. Finally, some miscellaneous notes are provided on the presence ofBalanites aegyptiaca,Callistemon viminalis,Grevillea robustaandPassiflora caeruleain Tenerife.
