“…In the Canary Islands its presence was noted so far in La Palma (Otto & Verloove 2016) and Tenerife (Verloove, unpublished records). It is here reported for the first time from Gran Canaria where it doubtlessly is relatively frequent but confused with K. daigremontiana.…”

“…It has long been confused with the similar-looking C. aethiopica (L.) N.E. Brown, not only in the Canary Islands (see Otto & Verloove 2016 for details about their separation) but also elsewhere in Europe, for instance in Italy (Grandis 2016). It was shown that most Canarian populations are in fact referable to C. floribunda, not to C. aethiopica.…”

“…It rarely reproduces from seed which may explain why it has rarely been reported as an escape of cultivation there. It has been known from La Palma since 2013 and since 2014 from Tenerife (Otto & Verloove 2016;Verloove 2017).…”

Verloove, F., Salas-Pascual, M. & Marrero Rodríguez, Á.: New records of alien plants for the flora of Gran Canaria (Canary Islands, Spain). -Fl. Medit. 28: 119-135. 2018. -ISSN: 1120-4052 printed, 2240-4538 online.Recent field work by the authors in Gran Canaria (Canary Islands, Spain) yielded records of non-native vascular plants that were not previously reported in the wild. Acokanthera oblongifolia, Alstroemeria ligtu, Capsicum annuum, Chasmanthe bicolor, Cotyledon orbiculata var. spuria, Digitaria setigera, Phlomis purpurea, Setaria pumila subsp. pallide-fusca, Solanum betaceum, S. seaforthianum, Syzygium cumini, Tecoma ×smithii, and Tradescantia spathacea are newly recorded for the Canary Islands whereas Bauhinia variegata, Chasmanthe floribunda, Crassula multicava, Cupressus sempervirens, Ficus rubiginosa, Galinsoga quadriradiata, Jacaranda mimosifolia, Kalanchoe ×houghtonii, Merremia tuberosa, Nerium oleander, Passiflora morifolia, Phytolacca dioica and Salvia hispanica are new records for the flora of Gran Canaria. Although several of these taxa are considered mere ephemerals at present, nearly all of them have the potential to naturalize and/or become invasive.

“…Fora de la seua zona d'origen es cultiva com a ornamental en països de clima càlid. Com a escapada de cultiu, a Espanya ha sigut localitzada a l'illa de La Palma (Otto & Verloove, 2016) i a nivell peninsular sols es coneix una cita anterior per a Catalunya, publicada recentment per Gómez-Bellver et al (2019b). Dins del BDBCV s'ha detectat una cita de l'any 1993 referida a Ondara (Alacant), la qual es tracta d'una dada procedent d'un exemplar conreat en jardineria i no naturalitzat (J. X. Soler, com.…”

Con las observaciones de los últimos años en el este de la península ibérica (concretamente en Cataluña, País Valenciano y la provincia de Teruel), se aportan un conjunto de datos corológicos de 41 plantas alóctonas naturalizadas u ocasionales. Cabe destacar Annona cherimola y Manihot grahamii que se citan por primera vez en la flora ibérica; Echinopsis pachanoi y Hydrocotyle verticillata para Cataluña; Solandra maxima en el País Valenciano. Se tiene que excluir Opuntia pestifer de la flora valenciana, ya que se confirma que las citas anteriores corresponden a Opuntia aurantiaca. Además, se aportan nuevas localidades de Acacia karroo, Cylindropuntia kleiniae, Euphorbia tirucalli, Leucaena leucocephala, Lophocereus marginatus, Nicandra physalodes, Pelargonium inquinans, Physalis peruviana, Podranea ricasoliana, Sedum pachyphyllum, Senna corymbosa, Tradescantia pallida y Tradescantia sillamontana, táxones interesantes y poco conocidos en la flora alóctona del este ibérico.

“…Even the first, seemingly anecdotic, reproduction of an ornamental is worth reporting, since it may constitute the first (but essential) step in a future naturalization process (Böcker et al, 1995). This paper is a sequel to Otto & Verloove (2016). We present new records for species that are either new to the Canary Islands (and even Macaronesia as a whole) or new to the island of La Palma.…”
