Zusammenfassung:Three new species of Eritrichium Schrad. ex Gaudin from boreal and arctic Alaska and Yukon are described: E. arenosum, E. boreale, and E. grandiflorum. These species are morphologically allied with the primarily Asiatic E. sericeum complex. Eritrichium arenosum is apparently restricted to sand dunes of the central Arctic Coastal Plain of Alaska. Eritrichium boreale and E. grandiflorum occur on mountain slopes and rocky summits from the western Brooks Range through the interior of Alaska, and east to Yukon, Canada. Se describen tres especies nuevas de Eritrichium Schrad. ex Gaudin de Alaska y Yukon boreal y árctico: E. arenosum, E. boreale, y E. grandiflorum. Estas especies están relacionadas morfológicamente con el complejo E. sericeum primariamente asiático. Eritrichium arenosum está aparentemente restringido a las dunas arenosas de la llanura central costera árctica de Alaska. Eritrichium boreale y E. grandiflorum aparecen en las laderas montañosas y cumbre rocosas de la Brooks Range occidental hacia el interior de Alaska, y por el este hasta Yukón, Canadá.
