“…The first escapees of this plant into the wild are likely to have originated from research centers or horticultural greenhouses. In recent years, however, domestic gardens are the most apparent source of incursions into the wild, particularly due to its popularity as a garden plant, at least in North America 7 , Australia 67 , and Europe 8,16 . For example, in Spain and Italy, K. × houghtonii has become a serious and invasive problem, likely stemming from its popularity as an ornamental plant owing to its low maintenance (C. Gómez-Bellver and A. Stinca, pers.…”

“…As far as we know, the present study is the first estimate of global range shifts under a scenario of climate change not only for a Crassulaceae species but also for CAM species. Studies carried out at local or regional levels have yielded equivocal results: some show a range expansion such as Kalanchoe × houghtonii in NW Spain 16 and Echinocereus reichenbachii (Terscheck ex Walp.) J. N. Haage in the United States 111 , whilst for others a range reduction was detected, e.g.…”

Invasive alien species are currently considered one of the main threats to global biodiversity. One of the most rapidly expanding invasive plants in recent times is Kalanchoe × houghtonii (Crassulaceae), an artificial hybrid created in the 1930s in the United States by experimental crossings between K. daigremontiana and K. tubiflora, two species endemic to Madagascar. Thanks to its large colonizing capacity (mainly derived from the production of asexual plantlets), K. × houghtonii soon escaped from cultivation and quickly spread in many parts of the world. However, its actual range is not well known due to the lack of a formal description until recent times (2006) and its strong morphological resemblance with one of its parentals (K. daigremontiana). The present study was aimed, in the first instance, to delimit the present distribution area of K. × houghtonii at the global scale by gathering and validating all its occurrences and to track its colonization history. Currently, K. × houghtonii can be found on all continents except Antarctica, although it did not reach a global distribution until the 2000s. Its potential distribution, estimated with MaxEnt modelling software, is mainly centered in subtropical regions, from 20° to 40° of both northern and southern latitudes, mostly in areas with a high anthropogenic activity. Unexpectedly, concomitant to a poleward migration, future niche models suggest a considerable reduction of its range by up to one-third compared to the present, which might be related with the Crassulaceaean Acid Metabolism (CAM) of K. × houghtonii. Further research may shed light as to whether a decrease in potential habitats constitutes a general pattern for crassulaceae and CAM plants.

“…It is also considered an invasive species in Florida and eastern Australia (Weber 2017 This species is morphologically similar to K. daigremontiana but distinguishable by the leaf base that is neither auriculate nor cordate (Ward 2006;Wang & al. 2016;Mesquida & al. 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.

“…Como consecuencia, muchas de ellas se han establecido fuera de su área de distribución natural (Mabberley, 1997). Algunos taxones han sido reportados como plenamente naturalizados e incluso invasores en regiones muy distantes (Randall, 2017), como Argentina (Hurrell et al, 2012), Australia (Palmer & Rafter, 2012), China (Wang et al, 2016), España (Mesquida et al, 2017) y Estados Unidos (Moran, 2009). En Cuba se han reportado varias especies del género teniendo en cuenta tanto las cultivadas como las que ya se han naturalizado.…”

Notas sobre las especies de <em>Kalanchoe (Crassulaceae)</em> ocasionales y naturalizadas en Cuba

Muchas especies del género Kalanchoe se cultivan ampliamente por su valor ornamental, hecho que junto a la alta capacidad de muchas de ellas a naturalizarse ha causado que algunas crezcan en zonas geográficas distantes de sus áreas de distribución natural. En los últimos 65 años el número de especies de Kalanchoe reportadas para Cuba ha ascendido de dos a cinco, según publicaciones recientes. La falta de un trabajo actualizado que recoja las especies naturalizadas de este género en Cuba y que aporte unas claves para su correcta identificación ha conducido a la existencia de discrepancias en cuanto a algunos de los nombres citados en estas publicaciones. A la vista de dichos precedentes creímos oportuno realizar la presente investigación que tuvo como objetivos definir el número real de especies de Kalanchoe que crecen de manera silvestre en Cuba, ofrecer una clave para su identificación, así como descripciones e información sobre las localidades donde han sido encontradas. Se estima que en Cuba crecen espontáneamente seis taxones de este género, de los que tres se reportan por primera vez, uno de los cuales, K. laetivirens, también es novedad mundial. Aportamos también imágenes y mapas que permiten una mejor comprensión de los resultados.
