Taxonomic notes on Napeanthus (Gesneriaceae) in Ecuador: neotypification of two species and a new species from the eastern Andean slopes

Ongoing field expeditions in Ecuador and herbarium research have resulted in the discovery of a new species and the stabilization of two names in Napeanthus (Gesneriaceae). Napeanthus robustus Fritsch and Napeanthus ecuadorensis Fritsch were both described from specimens housed at the Berlin herbarium that were subsequently destroyed; therefore, neotypes are designated to stabilize the application of these names. A third taxon, Napeanthus decurrens J. L. Clark, sp. nov., is described as a narrow endemic from the eastern Andean slopes of the Ecuadorian province of Zamora-Chinchipe.
