The shortage of reliable primary taxonomic data limits the description of biological taxa and the understanding of biodiver-sity patterns and processes, complicating biogeographical, ecological, and evolutionary studies. This deficit creates a significant taxo-nomic impediment to biodiversity research and conservation planning. The taxonomic impedi...

Plantas geralmente terrícolas, raramente rupícolas. Rizomas eretos, decumbentes ou curto a longo rasteiros, geralmente
revestido por escamas pilosas ou glabras. Frondes monomorfas, raramente subdimorfas, espaçadas a fasciculadas. Pecíolos não
articulados com o rizoma, nas bases com dois feixes vasculares em forma de cavalo marinho, que se unem em u...
The urge to organise the world around us is an essential part of human nature. Naming and categorising enable us to store and access information ef ciently. The need to name and categorise extends to the natural world and, in particular, to living organisms. The science underpinning this area of knowledge is called Taxonomy, and is as old as humani...
A new species, Serpocaulon australe, from the Yungas Montane Forest of Argentina and Bolivia, is described based on a re-interpretation of the name S. gilliesii. The new species is similar to S. lasiopus, but can be distinguished by its rhizome scales with entire margins and acute-acuminate apices, glabrous fronds with few axillary scales in the se...
Polypodium s.s. is currently a fern genus with about 40 species, and still with a controversial circumscription. The Flora of Brazil online reports just one Polypodium species in Brazil. Here we confirm the occurrence of a second species of the genus in Brazil, and present a taxonomic treatment of Polypodium from this country; this includes descrip...
The Global Strategy for Plant Conservation (GSPC) was established by the Conference of Parties in 2002 to decrease the loss of plant diversity, reduce poverty and contribute to sustainable development. To achieve this overarching goal, the GSPC has established a series of targets, one of which is to ensure that plant diversity is well understood, s...
This study adressed the Aspleniaceae taxa recorded in ferruginous formations of Serra dos Carajás, Pará state, bringing descriptions, illustrations, geographical distribution, and comments. In the study area one genus and four species were recorded: Asplenium formosum, Asplenium salicifolium, Asplenium serratum, and Asplenium stuebelianum.
This study addressed the Dryopteridaceae taxa recorded in ferruginous formations of Serra dos Carajás, Pará state, bringing descriptions, illustrations, geographical distribution, and comments. In the study area four genera and four species were recorded: Ctenitis nigrovenia, Dryopteris huberi, Elaphoglossum glabellum and Polybotrya sorbifolia.
This study addressed the Pteridaceae taxa recorded in ferruginous formations of the Serra dos Carajás, Pará state, with descriptions, illustrations, geographical distribution, and comments. In the study area nine genera and 10 species were recorded: Adiantopsis radiata, Adiantum deflectens, Ananthacorus angustifolius, Ceratopteris thalictroides, Do...
Two new species of Goniopteris endemic to the state of Espírito Santo (Brazil) are described and illustrated: Goniopteris bradei and G. salinoi. Morphological comparisons with similar species, as well as two identification keys, are presented. One key includes the Brazilian species most similar to G. bradei, and the other includes those Goniopteris...
Four new species of Goniopteris from Brazil are described and illustrated: Goniopteris smithii and G. windischii are narrowly endemic to southern Bahia, G. seidleri is restricted to the mountains of Espírito Santo and Rio de Janeiro states, and G. subdimorpha is endemic to semideciduous forests of Minas Gerais state.
