The Brazilian Atlantic Forest presents high levels of richness and endemism of several taxonomic groups. Within this forest, the Orchidaceae may be highlighted as the richest family of Angiosperms found there, and is highly threatened due to collection and habitat destruction. The inselbergs of the Brazilian Atlantic Forest are mostly unknown regar...

... arachnoideum, which is widespread in rocky environments (Schwartsburd et al. 2017;Yañez et al. 2020). In this way, we highlight the rocky environments as a potential habitat for plants that develop in ruderal habitats (Ibisch et al. 1995) due to the intense disturbances that they have been suffering, such as mineral exploration, illegal extraction of their biological diversity components, opening of roads and fires, among others (Meirelles et al. 1999;Pessanha et al. 2014). Ecological and geographic distribution issues of fern species can be used in extinction risk assessment processes since the 32 out of 34 taxa we have listed for rocky environments were not evaluated enough to be included in any conservation category (CNCFlora 2019). ...
