Ceradenia Itatiaiensis, A New Species of Polypodiaceae from Southeastern Brazil

Recent collections of Polypodiaceae in Brazil reveal a new species of Ceradenia L. E. Bishop, C. itatiaiensis Labiak & Condack, that appears to be a narrow endemic to the Itatiaia National Park. It resembles C. albidula (Baker) L. E. Bishop, but differs mainly by having setae on the laminar margins. Descriptions and illustrations are provided, as well as comments on the most closely related species.
