Abstract

While working on the taxonomy of Ctenitis (Tectariaceae) from Brazil we detected two species that needed to have combinations in that genus: Ctenitis abyssi (Sehnem) Salino & Morais comb. nov. and Ctenitis laetevirens (Rosenst.) Salino & Morais comb. nov. The first species is similar to Ctenitis nigrovenia (H. Christ) Copel., but differs mainly by the short-creeping stem and ctenitoid hairs on the segment margins. Ctenitis laetevirens is related to C. submarginalis (Langsd. & Fisch) Ching, but differs by having pinnae long-petiolulate, ctenitoid hairs absent on the segment margins, the abaxial side of costae, costule and veins, and by having exindusiate sori.
