Epiphytes are hyper‐diverse and one of the frequently undervalued life forms in plant surveys and biodiversity inventories. Epiphytes of the Atlantic Forest, one of the most endangered ecosystems in the world, have high endemism and radiated recently in the Pliocene. We aimed to (1) compile an extensive Atlantic Forest data set on vascular, non‐vascular plants (including hemiepiphytes), and lichen epiphyte species occurrence and abundance; (2) describe the epiphyte distribution in the Atlantic Forest, in order to indicate future sampling efforts. Our work presents the first epiphyte data set with information on abundance and occurrence of epiphyte phorophyte species. All data compiled here come from three main sources provided by the authors: published sources (comprising peer‐reviewed articles, books, and theses), unpublished data, and herbarium data. We compiled a data set composed of 2,095 species, from 89,270 holo/hemiepiphyte records, in the Atlantic Forest of Brazil, Argentina, Paraguay, and Uruguay, recorded from 1824 to early 2018. Most of the records were from qualitative data (occurrence only, 88%), well distributed throughout the Atlantic Forest. For quantitative records, the most common sampling method was individual trees (71%), followed by plot sampling (19%), and transect sampling (10%). Angiosperms (81%) were the most frequently registered group, and Bromeliaceae and Orchidaceae were the families with the greatest number of records (27,272 and 21,945, respectively). Ferns and Lycophytes presented fewer records than Angiosperms, and Polypodiaceae were the most recorded family, and more concentrated in the Southern and Southeastern regions. Data on non‐vascular plants and lichens were scarce, with a few disjunct records concentrated in the Northeastern region of the Atlantic Forest. For all non‐vascular plant records, Lejeuneaceae, a family of liverworts, was the most recorded family. We hope that our effort to organize scattered epiphyte data help advance the knowledge of epiphyte ecology, as well as our understanding of macroecological and biogeographical patterns in the Atlantic Forest.

ABSTRACT(Ferns and Fern allies from Santa Catarina State: a "look at the data" from Santa Catarina Floristic Forest Inventory, Brazil). Santa Catarina is the fi rst Brazilian state to complete its Forest and Floristic Inventory, and is considered one of the states with a well-known fl ora. Th is region is covered by evergreen tropical rain forest, Araucaria forest, seasonal deciduous forest and associated ecosystems, and shows high species richness. Th is paper presents a list of ferns collected in 563 sampling units. Altogether, 324 species were recorded (300 ferns and 24 lycophytes), which belong to 29 families and 94 genera. Th e most diverse families are Polypodiaceae (49 species), Pteridaceae (42), and Dryopteridaceae (38). Asplenium and Th elypteris are the most diverse genera, with 27 species each, followed by Blechnum (15). Of importance, too, are the 75 species considered endemic to the biome. Eighteen new records for the fl ora of Santa Catarina were made. Th e distribution of species according to the vegetation type is the following: 288 species occur in evergreen tropical rainforest (of which 128 are exclusive to this vegetation type); 177 species in Araucaria forest (30 exclusively) and 57 species in seasonal deciduous forest (3 exclusively). In addition, 17 species were recorded for restinga. A collection of Asplenium lacinulatum, from an area of intense development, is fi rst record for Santa Catarina, and another of Alansmia senilis is the fi rst record for the South Region of Brazil.
abstraCt. In 2013, Caetano and colleagues published two lists of the Orchidaceae of the Municipality of Benedito Novo, Santa Catarina, totalling 99 species. Between January 2014 and September 2016, additional field trips were made and new species were found in the region. Thus, in this paper an updated checklist of the Orchidaceae of Benedito Novo is presented based on herbarium collections and field surveys. A total of 184 species distributed in 66 genera are registered, comprising about 35% of the species and 60% of the genera cited for Santa Catarina. The richest genera are Acianthera Scheidw.
