Abstract

Based on studies of Piperaceae from Brazil, two new species are described that belong to Piper section Ottonia from the state of Espírito Santo. Piper bicorne is recognized by membranaceous, densely glandulosous leaves, and a bifid prophyll. Piper aghaense is recognized by lanceolate leaves with a cordate to lobate base with one side overlapping the petiole. We present descriptions, illustrations and comments about the ecology and conservation of these species.
