“…In these works, the author describes 17 species of Blechnum L. and eight of Loma-ria Willd. Nowadays, numerous regional works can be referred, e.g., Pietrobom & Rosário (2008), Dittrich et al (2007Dittrich et al ( , 2015Dittrich et al ( , 2018, Salino et al (2017) and, among them, the 'Flora Ilustrada Catarinense', published by Aloysio Sehnem. In his Blechnaceae treatment, Sehnem (1968) recognized three genera (Blechnum, Salpichlaena, and Stenochlaena) and described 29 taxa.…”

We reviewed the fern family Blechnaceae in Santa Catarina, southern Brazil, in order to update the work done by Sehnem in Flora Ilustrada Catarinense. Ten genera and 21 species in the family have been recognized. In this work, descriptions and identification keys for the species are presented, as well as comments and a comparative list of Sehnem’s nomenclature and the current state-of-the-art in Blechnaceae nomenclature.

Edaphic Endemism in the Amazon: Vascular Plants of the canga of Carajás, Brazil

et al. 2019

Amazonia is one of the most diverse biomes worldwide, and, as well as luxuriant forest, it includes mountain areas which, despite their small surface area, display fascinating endemism. In these regions, the specificity of edaphic factors is mirrored by a highly specialised, isolated flora adapted to survive adverse conditions. The Serra dos Carajás in the Brazilian state of Pará is one of world's largest iron ore reserves. Known locally as canga, this ironstone formation occupies an area of 115.9 km 2 , and supports campo rupestre of canga vegetation on outcrops that are mostly in the Floresta Nacional de Carajás (FLONA of Carajás) and Parque Nacional dos Campos Ferruginosos (PNCF). The recent publication of the Flora of the cangas of Carajás lists 856 species of seed plants and 186 species of ferns and lycophytes. This project assessed the canga endemic species growing in the region, and further expeditions guided by SDM were carried out in order to ascertain their distribution outisde the area. Departing from an initial list of 58 putative endemics, the final list comprises 38 species of vascular plants (c. 4% of the local flora). These are distributed in 31 genera and 22 families, including three monotypic genera: Carajasia (Rubiaceae), Monogereion and Parapiqueria (Asteraceae). From these, 24 are classified as Rare Species for Brazil and seven as Highly Restricted Endemic (EEO < 100 km 2). An illustrated account is provided, as well as further SDM to detect other possible areas of distribution based on the studied species. The knowledge generated is aimed at directing appropriate conservation plans for the area.

In the state of Pará (Brazil), until the beginning of last decade little was known about the composition of the fern and lycophyte flora. The ferruginous mountains of Carajás are located in Southeastern Pará, mostly inserted in the Floresta Nacional de Carajás. The objective of this work is to present a complete and updated list of fern and lycophyte species occurring in all vegetation types from Carajás ferruginous mountains as a contribution to the knowledge of these plant groups from the Brazilian Amazon. The species list was based on specimens collected between 2007 and 2013. About 1068 specimens deposited in the BHCB Herbarium were studied. A total of 186 species of pteridophytes were recorded, 175 species of ferns distributed in 22 families and 68 genera, and 11 species of lycophytes distributed in three families and four genera. The fern and lycophyte flora of Serra dos Carajás region corresponds to 64% of the Pará state flora of these groups and 34% of the Brazilian Amazon fern and lycophyte flora. Seven taxa are presented as new records for Pará state: Asplenium abscissum, A. otites, A. praemorsum, Blechnum lanceola, Elaphoglossum minutum, Doryopteris collina, and Hemionitis tomentosa. Three species are endemic to Serra dos Carajás, Isoetes cangae, I. serracarajensis, and Selaginella stomatoloma.
