Abstract Background and Aims The dynamics of genome evolution caused by whole duplications other processes are hypothesized to shape the diversification plants thus contribute astonishing variation in species richness among main lineages land plants. Ferns, second most species-rich lineage plants, highly suitable test this hypothesis because several unique features that distinguish fern genomes from those seed In study, we tested diversity disparity recording parameters related size...
La construcción de la Represa Hidroeléctrica Yacyretá impactó manera notable en los ecosistemas aledaños. Para mitigar estos efectos, Entidad Binacional creó áreas protegidas, como Reserva Natural Rincón Santa María (RNRSM) y Mbaracayá (RNMb) Ituzaingó, Corrientes, Argentina. RNRSM alberga bosques secundarios restauración pinares abandonados, mientras que RNMb —más afectada por las obras represa— presenta vegetación secundaria recuperación. El objetivo este trabajo fue inventariar especies...
An ethnobotanical study was performed of the ferns and lycophytes used by Guaraní Misiones Province, Argentina. It determined that fifty species are used, details uses names nomenclature given discussed. Fern for medicines, crafts, in magic rituals, marketing plants. The most important traditional use is medicine modern commercialization horticulture.

The genus Ophioglossum has around 25 species with a nearly cosmopolitan distribution. It historically posed number of taxonomic problems due to the lack morphological characters upon which base delimitations. In order address this, we analyzed sculpture patterns spores from ten critical taxa southern South America. Palynological data was compared morphology sporophyte. sculpturing pattern most valuable and consistent character delimitation in Ophioglossum. Nomenclatural types studied were...
The genus Botrychium (Ophioglossaceae) is comprised of about 30 widely distributed species. Because their small size and few, yet variable, morphological characters, many questionable taxa have been described over the years. Since its description in 1906, B. dusenii has treated as both a distinct species variously divided into four taxa: lunaria var. dusenii, typicum, antarctica, ramosum patagonicum (B. matricariaefolium subsp. patagonicum). aim this study to evaluate validity these using...
The diversity of ferns and lycophytes Corrientes province, Argentina is not well understood.Our fi eld work in the Mburucuyá National Park province as a literature review nds 29 genera 48 infrageneric taxa for this Park.A comparison Park's species with other protected areas northeastern using Jaccard's similarity coeffi cient biodiversity index proposed by Squeo et al. (1998) are analized.A key to provided.
The name Isoetes pedersenii H.P. Fuchs (Lycophyta), a species known only from the Mburucuyá National Park, Corrientes, Argentina, is validated. Observations were carried out on herbarium material with stereoscopic, light and scanning electron microscopes. described typified. A diagnosis discussion about its distribution relationship morphology of other are provided.
Introducción y objetivos: Algunas especies de helechos cheilanthoideos son caracterizados por presentar adaptaciones a hábitats xéricos. Además, presentan la particularidad enrollar sus láminas frente condiciones stress hídrico. Sin embargo, al retornar las ambientales óptimas se vuelven expandir. El objetivo este trabajo es proporcionar información morfo-anatómica frondes asociar estructuras anatómicas estos movimientos foliares.M&M: Se estudiaron mediante microscopía óptica electrónica...
New Records of Ferns from Northeastern Argentina and Uruguay.-Fourrecords ferns are reported here for the first time, two species northeastern others Uruguay.In addition, occurrence other is documented with herbarium specimens both countries.

Lectotypificationof Asplenium sellowianun C. Presl ex Hieron.and lated Names.-During the development of Project "'Flérula del Parque Nacional Mburucuya'', subproject ''Flora Pteridofitica'', some nomenclatural problems were found, including need to lectotypify sellowianum and names which are included in synonymy.The name was first published by Pres] (Tent.Pterid.:107.1836).Pres] placed this taxon subgenus Asplenium, within species group ''frons herbacea''.In work, author mentions only...
