Columnea puipuiense R.Rojas & Vásquez, sp. nov., and Columnea valenzuelai, R.Rojas & Vásquez, sp. nov., two new species of Gesneriaceae endemic to the Bosque de Protección Pui Pui, central Peru, are described and illustrated. Their morphological affinities with related species of the genus Columnea are discussed, and complete descriptions are provided, including diagnostic characters, ecological information, and geographic distribution. With the recent discovery of Columnea yanachagaensis R.Rojas, A.Monteagudo & J.Flores and C. cesarii R.Rojas, Vásquez & L. Valenz, along with the discovery of Columnea puipuiense and Columnea valenzuelai, the number of Columnea species recorded for Peru increases to 36. These findings raise the documented diversity of Peruvian Gesneriaceae to 227 species.
