The Ferns of Brazilian Amazonia
No full textAbstract An annotated list of the pteridophytes of Brazilian Amazonia is presented, with the geographic occurrence of the species by States and Territories. The flora includes 12 families, 58 genera and 279 species, with only four species possibly endemic. Two new combinations are Arachnoides macrostegia (Hook.) Tryon & Conant and Thelypteris juruensis (C. Chr.) Tryon & Conant. Some general comments on the geography of Amazonian ferns are included as well as ecological studies presenting data on the local environmental preferences of six species.</jats:p

Further examination has proved this to be the case and it is here described as new.
