This work presented the inventory of ferns and lycophytes of Jaú, São Paulo state. Sixty-eight species of ferns and one of lycophyte were recorded, distributed in 16 families and 32 genera. The richest families were Pteridaceae and Thelypteridaceae with 15 species each, Polypodiaceae (7spp.), Blechnaceae and Dryopteridaceae (5 spp. each). The most common guild of life form was terrestrial herbs with 57 species, followed by epiphytes (6 spp.), arborescent, aquatic and lithophytes (2 spp. each) and hemiepiphytes and scandents with one species each. The analysis of the geographical distribution showed that 46% of the species (32 spp.) occur in the Neotropics, 20 species occurs in Southern America, eight are endemic of Brazil, five pantropical and four are exotic. This study can further collaborate in the protection and preservation of the few remnants which represent probably the last areas where some species of these groups of plants occurring in the municipality.

In 2016, municipal ordinances to expand the protected area of the MHRWS were issued with the aim of protecting and preserving the remaining biodiversity of the buffer zones and to strengthen the core zone. The municipal ordinances however, have limitations and do not guarantee legal promulgation. Hence, this study is on the gathering of complete and concrete floral data so that these expansion sites will become part of the protected area and encompassed in legal promulgations. Botanical fieldworks conducted from Oct to Dec 2017 were carried out in five study sites of the MHRWS expansion sites using 40 20 x 20 m sampling plot with a distance of 20 m between plots and opportunistic transect walk techniques. The study disclosed 228 taxa of plants, of these, 74 species were ferns and lycophytes, 6 species of gymnosperms, 30 species of herbs and vines and 118 species were trees and shrubs. There were three new records of ferns and lycophytes increasing the number of species to 155. There are 13 (5.7%) threatened species, 22 (9.6%) and endemic species. Findings suggest that species in each site are unique and maybe attributed to the vegetation present, elevation variations of the different sampling sites and anthropogenic activities. The proposed expansion sites harbor diverse threatened and plants deserving protection and conservation efforts. Results of this study support the contention that the expansion sites, which are included in the municipal ordinances, be part of the official protected area.

Abstract The Northeastern Atlantic Forest (NAF) has a historic of intense habitat loss and fragmentation. In this context, knowledge of the species from forest remnants is urgently needed and represents a key tool for future studies and conservation strategies. Here, we present the floristic inventory of ferns and lycophytes from the Private Natural Heritage Reserve - RPPN Pedra D'Antas, located in a NAF area. The study area associated with the RPPN Frei Caneca is the Serra do Urubu, which is a hotspot for the diversity of several biological groups in the NAF. We recorded 74 fern species, distributed in 17 families and 46 genera. The most diverse families were Pteridaceae (17 species), Polypodiaceae (14 spp.), Dryopteridaceae (nine spp.) and Thelypteridaceae (seven spp.). Lycophytes were represented by four species, two families and two genera. A new record for the Northeast of Brazil, Serpocaulon hirsutulum, is presented in this study. The area has a large number of species, some of which are restricted to the NAF (e.g. Megalastrum umbrinum). Based on the richness of the study area associated with another inventory held at the RPPN Frei Caneca (138 spp.), the Serra do Urubu is corroborated as a hot-spot for the diversity of ferns and lycophytes in the NAF.

The veracity of records of the 11 presumed Extinct or missing ferns and lycophytes from the Wet Tropics Bioregion of northern Queensland is investigated by examination of original materials and by intensive field searches of their recording sites. Two of the species, namely Hymenophyllum whitei and Oreogrammitis leonardii, were rediscovered. One of the species, Lastreopsis dissecta, is taxonomically problematic. Another taxon, Lindsaea pulchella var. blanda, is excluded as an erroneous record. The remaining seven species, namely Didymoglossum exiguum, Haplopteris dareicarpa, Huperzia serrata, Hymenophyllum lobbii, Lemmaphyllum accedens, Pseudodiphasium volubile and Tmesipteris lanceolata, all having been recorded by Karel Domin, appear to be questionable records and their presence in Australia requires ongoing consideration unless they are relocated or can be otherwise excluded.

We present the floristic survey of ferns and lycophytes from the “Parque Estadual Turístico do Alto Ribeira” (PETAR), a remnant of Atlantic Rain Forest of Southeastern Brazil, in São Paulo state. Besides a complete list of species, we also provide information on habit, geographic distribution, and conservation status. Among the 237 taxa, there are 235 species, one variety and one hybrid, distributed in 29 families and 74 genera. Ferns are represented by 223 taxa, whereas the lycophytes were represented by 14. The most representative families are Polypodiaceae (31 spp.), Pteridaceae (29 spp.) and Dryopteridaceae (28 spp.). The most diverse genera are Thelypteris (23 spp.), Asplenium (19 spp.), Elaphoglossum and Blechnum (10 spp. each). Noteworthy is the presence of Ctenitis anniesii, Dicksonia sellowiana, Elaphoglossum iguapense, E. prestonii, E. strictum, Thelypteris concinna, T. araucariensis and T. hatschbachii, all of them considered as endangered species in São Paulo state.
