Resumen

Durante un trabajo de campo reciente, en diciembre de 2023 y 2024, se descubrieron por primera vez en Gran Canaria (Islas Canarias, España) varias especies de plantas no autóctonas interesantes. Algunas también se citan por primera vez en todo el archipiélago canario. Casi todas las especies han escapado del cultivo ornamental y su estatus varía desde más o menos naturalizada hasta (para la mayoría de las especies) ocasional. Sin embargo, estas últimas especies tienen el potencial de naturalizarse con el tiempo o, en el peor de los casos, convertirse en invasoras, ya que todas son conocidas como malas hierbas o invasoras en otras partes del mundo con un clima similar. Se trata las siguientes especies: Cynodon nlemfuensis, Delonix regia, Euphorbia umbellata, Ficus lyrata, Helianthus annuus, Koelreuteria paniculata, Physalis peruviana, Psilotum nudum, Ruellia simplex, Solanum mauritianum, Tithonia diversifolia y Volkameria inermis. También se añaden notas diversas para otras especies de interés, como son Cyperus brevifolius, Digitaria setigera, Euphorbia cyathophora y Setaria geminata.
