Background Recent fieldwork by the author in Tenerife, mostly between 2014 and 2019, yielded new records of alien vascular plants. New information 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 dipteracanthus and Wigandia 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 alata and Urochloa subquadripara. Finally, some miscellaneous notes are provided on the presence of Balanites aegyptiaca, Callistemon viminalis, Grevillea robusta and Passiflora caerulea in Tenerife.

特内里费岛外来维管植物的新记录（西班牙，加那利群岛）

背景 作者最近在特内里费岛进行的实地考察，主要是在 2014 年至 2019 年之间，产生了外来维管植物的新记录。新信息 十五种分类群（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 venus Ruellia dipteracanthus 和 Wigandia kunthii) 首次在加那利群岛报道。所有最初都是故意引入的，主要是作为观赏植物，最近开始逃离种植。它们中的大多数是短暂的或仅在当地建立，但几乎所有这些都具有在未来归化的潜力。特内里费岛首次报道了另外 13 个物种：Atriplex nummularia，Bellis perennis, Chenopodium probstii, Coccoloba uvifera, Commelina benghalensis, Cuphea hyssopifolia, Eragrostis virescens, Lemna minuta, Malvastrum corchorifolium, Plerandra Elegantissima, Psidium guajava, Thunbergia alata and Urochloa subquadripara。最后，提供了一些关于在特内里费岛存在的 Balanites aegyptiaca、Callistemon viminalis、Grevillea robusta 和 Passiflora caerulea 的杂项说明。
