Abstract

Three new species of Valeriana from southern Ecuador are described and illustrated. Valeriana plateadensis is found near the highest peak of Cerro Plateado in Cordillera del Cóndor at 2900 m a.s.l. and is recognized by the shrubby habit and sessile, densely imbricate, spatulate leaves and 3-lobed corollas. V. yacuriensis is found near Lagunas Negras de Jimbura in the Parque Nacional Yacurí at 3500 m a.s.l. and is recognized by the shrubby habit, petiolate leaves and 3-lobed corollas. V. xenophylloides is found in the Páramo de Patococha at 3400 m a.s.l. and is recognized by its cushion growth form, the crown of trichomes at the leaf apex and 3-lobed corollas.
