New approaches in the fern genus Pteris (Pteridaceae) from Brazil
Background and aims: Pteris is widely distributed with ca. 65 species in the Tropics. In Brazil, 24 species were recognized and five of them are endemic to the Atlantic Forest. The objective of the present paper is to re-evaluate the taxonomy of Pteris occurring in Brazil, based on new morphological...

Background and aims: Pteris is widely distributed with ca. 65 species in the Tropics. In Brazil, 24 species were recognized and five of them are endemic to the Atlantic Forest. The objective of the present paper is to re-evaluate the taxonomy of Pteris occurring in Brazil, based on new morphological evidence of old and recent specimens deposited in herbaria, analysis of types, and observations in the field.
M&M: The new approaches are based on morphological data such as SEM images of the spores and from the examination of herbarium collections mainly from SP and RB Herbaria.
Results: Four species are being recognized in the present paper (P. lata, P. organensis, P. praealta, and P. sericea). For two of them, two new combinations into Pteris are presented: P. organensis and P. praealta. A key to distinguishing the newly recognized species and its relative taxa, as well as descriptions, illustrations, and comments are presented in this paper.
Conclusions: By reviewing herbarium materials, mainly observing the morphology of the spores, and collecting more specimens in the field, it was possible to recognize three species (Pteris lata, P. organensis, and P. praealta) in Brazil and also verify the correct application of the name Pteris sericea to the Brazilian plants. All these names had been previously synonymized in previous studies. After this study, 27 species of Pteris are recognized in Brazil. |

Introducción y objetivos: Pteris está ampliamente distribuido con ca. 65 especies en los trópicos. En Brasil fueron reconocidas 24 especies y cinco de ellas son endémicas de la Mata Atlántica Brasileña. El objetivo del presente artículo es reevaluar la taxonomía de Pteris presentes en Brasil, con base en nueva evidencia morfológica obtenida de especímenes antiguos y recientes depositados en herbarios, análisis de tipos y observaciones de campo. M&M: Los nuevos enfoques se basan en datos morfológicos, como imágenes SEM de las esporas, y en el examen de colecciones de herbarios, principalmente de SP y RB Herbaria. Resultados: En el presente artículo se reconocen cuatro especies (P. lata, P. organensis, P. praealta y P. sericea). Para dos de ellos se presentan dos nuevas combinaciones en Pteris: P. organensis y P. praealta. En este artículo se presenta una clave para distinguir las especies recientemente reconocidas y sus taxones relacionados, así como descripciones, ilustraciones y comentarios. Conclusiones: Al revisar los materiales de los herbarios, observando principalmente la morfología de las esporas y recolectando más especímenes en el campo, fue posible reconocer tres especies (Pteris lata, P. organensis y P. praealta) en Brasil y también verificar la correcta aplicación del nombre Pteris sericea a las plantas brasileñas. Todos estos nombres habían sido previamente sinonimizados em estudios anteriores. Después de este estudio, se reconocen 27 especies de Pteris en Brasil.
