“…As part of a broader study, whose objective is to study the diversity of ferns and lycophytes in the Paranaense forest with emphasis on the protected areas of northeastern Argentina (Marquez et al 2016(Marquez et al , 2020Kelly et al 2019;Yañez et al 2022), Pteris ensiformis is recorded for the first time in the country, growing in the province of Misiones. In the present work the populations found are documented, the species is illustrated, and a key is provided to distinguish it from the Pteris species from Argentina.…”

Pteris has numerous representatives of Asian and Oceanic origin naturalized in America, some of them recognized as invasive weeds. Pteris ensiformis was introduced in America in the middle of the 19th century and subsequently naturalized in USA and Central America, but the records of its distribution in South America are isolated and the establishment or naturalization of the populations is unclear. As part of a broader study whose objective is to review the diversity of ferns and lycophytes in the Paranaense forest P. ensiformis was found for the first time in Argentina. In addition to describing, illustrating, and distinguishing the species from other species of the genus in the country, we review the distribution of P. ensiformis in South America comparing herbarium collections and iNaturalist observations, a citizen science platform. Additionally, a status for the species is proposed or suggested in each country where it is registered according to its stage of the naturalization process.

The Yabotí Biosphere Reserve (Prov. Misiones, Argentina) with 221,155 ha, represents one of the southernmost relicts of the Paranaense forest. Currently, a project is being developed in the area to inventory and describe the ferns and lycophytes. As a result of these studies, we identify a new species of Amauropelta, A. yabotiensis. Within this genus, it belongs to the group of species with uncinate hairs and presents a unique combination of diagnostic features, including the type of pubescence on the rhizome scales, the shape of the fronds and segments and type of venation. Here, we described and illustrated the species and we analyzed its taxonomic affi nities and geographic distribution. Additionally, we provided a distribution map and a key to distinguish it from other Amauropelta species from Misiones province. With this new fi nding, we highlighted the importance of the Yabotí Reserve as a reservoir of biodiversity in the region.
