Description
Summary:Patterns maritima is a small cushion-forming subshrub known from the Western Mediterranean region, extending to S. Portugal along the Atlantic Coast. It is reported here for the first time for California, being documented for the first time as growing outside of cultivation in North America. In Orange County, southern California, it has naturalized along the immediate coast on rocky shores and sea cliffs mostly within the salt-spray zone. Patterns marítima is cultivated in California and likely escaped from residential gardens, commercial landscapes, nurseries, or similar sources. We cite voucher specimens, describe the habitat, and comment on presumed mode of introduction. A review of the taxonomy and nomenclature of the Asteriscus alliance is provided. Patterns marítima is one of a growing number of salt-tolerant ornamental plants that have become naturalized recently in southern California. Pallenis maritima es un pequeño subarbusto pulviniforme, conocido en la región Mediterránea occidental y a lo largo de la costa atlántica hasta el sur de Portugal. Se reporta aquí de California, siendo documentada por primera vez como creciendo de forma silvestre en América del Norte. En el Condado de Orange, al sur de California, se ha naturalizado en las costas rocosas y acantilados a lo largo de la costa colindante, sobre todo en la zona de niebla salina. Pallenis marítima se cultiva en California y es probable que provenga de jardines residenciales, servicios comerciales de diseño de jardines o fuentes similares. Se citan especímenes, se describe el habitat y se comenta el probable modo de introducción. Se presenta una sinopsis de la taxonomía y la nomenclatura del complejo de Asteriscus. Pallenis marítima es una de las cada vez más numerosas plantas ornamentales tolerantes de la salinidad que se han naturalizado recientemente en el sur de California.
