A new species of Merremia Dennst. ex Endl. (Convolvulaceae) with tuberous roots from northern Peru named Merremia sagastegui-alvae E. Rodr., J. Briceño, B. Billman, A. Boswell is described and illustrated. The new species was identified close to the town of Collambay (Simbal District, Trujillo Province, La Libertad Region, Peru) between 950 and 1830 m a.s.l. The species is apparently endemic to this part of the country. We discuss the new species in relation to Merremia grandiflora Ooststr. and present additional data on its geographic location, ecological zone it inhabits, phenology, uses, common names and current conservation status.
