J. Mario Salazar-Cesena Robert H. Webb 2011 <i>Agave turneri</i>, a new species of Agave from the Sierras Cucap&#225; and El Mayor in northeastern Baja California, Mexico, is a medium-sized species that does not produce offsets, has a relatively short and narrow panicle, and has a distinctive flower structure. The closest relatives to this new species are <i>Agave moranii</i>, which occurs approximately 200 km to the south of the type locality, and <i>A. deserti</i> var. <i>simplex</i>, which occurs in Arizona and California. This new species is a narrow endemic restricted to specific granodiorite and tonalite habitats in a hyperarid environment. <i>Agave turneri</i> appears to be a critically endangered owing to its habitat preference for specific types of granite in the Sierra Cucap&#225;, threats due to prolonged drought and global change, and its close proximity to the Mexicali metropolitan area. application/pdf 10.1007/s12228-010-9151-3 en New York Botanical Garden Press Agave turneri (Agavaceae), a new species from northeastern Baja California, Mexico article
